Which Submersible Pump Do You Need? — Range Comparison Cosmos Pumps manufactures six submersible pump models across four ranges. Match your fluid type and site conditions to the right model:CDW — Dewatering (Standard): 450–8,500 LPM, up to 86.5 M head, 1.5–50 HP. Solids up to 12 mm. Best for construction, basements, tunnels, mines (clean water). CDW High Head — Dewatering: 350–2,200 LPM, up to 140 M head, 5–75 HP. Solids up to 12 mm. Best for deep tunnels, mines, hydro power plants. CDW Ultra High Head — Dewatering: 50–200 m³/h, up to 200 M head, 50–120 HP. Best for major tunnels, deep mines, large infra projects. CNC — Non-Clog / Vortex: 1,250–1,500 LPM, up to 30 M head, 6–20 HP. Solids up to 70 mm. Best for sewage bypass, manhole cleaning, thick sludge. CSW — Sewage: 775–33,000 LPM, up to 60 M head, 2–200 HP. Solids 20–100 mm, SG up to 1.7. Best for municipal, STP/ETP, residential sewage. CSL — Slurry (Hi-Chrome): 1,584–5,834 LPM, up to 52.5 M head, up to 100 HP. Solids up to 70% by weight, SG up to 2.1. Best for mining, ash transfer, harbour dredging, power plants. CSL-TV — Slurry Twin Volute: Same specs as CSL, with improved hydraulic balance for extended bearing life in continuous duty.Quick selector: Clean construction runoff / groundwater → CDW. Large solids or sewage → CNC or CSW. Heavy slurry (mines, ash, dredge) → CSL. High discharge head (deep tunnels / mines) → CDW High Head or CDW Ultra High Head. Frequently Asked Questions What is the difference between CDW and CNC submersible pumps?The CDW (Dewatering) pump handles dirty or muddy water with solids up to 12 mm — ideal for construction sites and tunnels. The CNC (Non-Clog) pump uses a vortex impeller and handles solids up to 70 mm including thick sludge — used for sewage bypass and manhole cleaning. Choose CDW for volume dewatering; choose CNC when solids or sludge concentration is high. What is the difference between a submersible dewatering pump and a sewage pump?A submersible dewatering pump (CDW series) handles dirty or muddy water with small suspended solids (4–12 mm) at SG up to 1.1. A sewage pump (CSW series) handles sewage and wastewater with larger solids (20–100 mm) at higher specific gravity (up to 1.7). Do not use a dewatering pump for raw sewage — it will clog or fail. Which submersible pump is best for mining dewatering?For mine dewatering with high discharge head requirements, choose CDW High Head (up to 140 M) or CDW Ultra High Head (up to 200 M). For mines with slurry, ash, or tailings, choose the CSL (SG up to 2.1). The CDW standard range is not suitable for slurry duty. What HP submersible pump do I need for a construction site?The CDW range spans 1.5–50 HP (450–8,500 LPM). Rule of thumb: small sumps / basement → 3–5 HP; open foundation excavation → 5–20 HP; large tunnels or quarries → 20–50 HP. Contact Cosmos for a free pump sizing assessment. Can Cosmos submersible pumps handle seawater or saline water?Yes. The CDW range is available with an SS316 variant and optional sacrificial zinc anode for seawater and high-salinity environments. Specify the SS316 variant at time of enquiry for coastal or offshore applications.
A submersible pump is a motor-pump unit sealed inside a waterproof housing, designed to operate fully submerged in the liquid being pumped — eliminating suction lift requirements, priming steps, and above-ground pipework to the unit. Our submersible range covers five series — CDW, CNC, CSW, CSL, and CSL-TV — spanning 1.5 HP to 200 HP and handling every liquid from clean construction runoff through to 70%-solids slurry at a specific gravity of 2.1.
The primary selection driver is liquid type: solids size and specific gravity determine which series fits your application, while duty flow rate and total dynamic head determine the HP rating and sub-variant within that series. For surface-mounted alternatives up to 1,550+ HP, see our CAP Auto-Prime pump range or the CSP Self-Priming surface pump.

Get Series Recommendation from iDEWAThe CDW Series is our core submersible dewatering pump line, engineered for construction sites, tunnels, mines, and infrastructure projects handling dirty or muddy water with suspended solids up to 12 mm and specific gravity up to 1.1. The range spans 1.5 HP to 120 HP across three head variants — Standard, High Head, and Ultra High Head — making it the most versatile dewatering series in the portfolio.
The CDW Standard is the highest-volume site dewatering pump, handling flows from 450 LPM to 8,500 LPM at shut-off heads up to 86.5 M. Built with an aluminium alloy stator casing for superior heat dissipation over cast iron, Class H insulation rated to 180°C, and twin stainless steel mechanical seals (TC vs TC), the CDW Standard is designed for continuous duty in abrasive, muddy water without surface drying. An adjustable wear plate gap (±5 mm at site, no disassembly required) maintains hydraulic efficiency across the pump's service life.
Key features: 15 m waterproof PVC power cable · SS-304 hardware and strainer · Nitride-hardened SS-410 impellers (HRC 52–55) · Sacrificial zinc anode option for saline or seawater applications · Lightweight modular design with Al alloy top bracket. Available in SS-316 wetted-parts variant for coastal and marine deployments.
Where standard head is insufficient — deep tunnels, underground mines, multi-stage hydro projects, and high-rise construction sumps — the CDW High Head variant extends shut-off head to 140 M with flow rates from 350 LPM to 2,200 LPM. HP range 5–75 HP covers mid- to large-scale drainage duties at elevated discharge pressures. The same Class H insulation, twin TC/TC mechanical seal, and aluminium alloy casing apply, with upgraded impeller stage geometry tuned for high-head performance.
The CDW Ultra High Head variant addresses the most demanding underground dewatering requirements: shut-off heads up to 200 M, flow rates up to 200 m³/h, and HP ratings from 50 to 120. A 2-stage SS-316 impeller, CI FG300 motor body, dual SiC vs SiC mechanical seal with oil seal, Viton rubber parts for saline and high-abrasive tolerance, and an SS-431 high-torsional-strength shaft deliver the hydraulic robustness required for deep mine, hydro power, and major tunneling projects. The motor incorporates a thermal sensor and a naturally cooled design that operates effectively in submerged or partially submerged conditions.
| CDW Variant | HP Range | Flow Rate | Max Shut-Off Head | Best For |
|---|---|---|---|---|
| CDW Standard | 1.5–50 HP | 450–8,500 LPM | 86.5 M | Construction sites, highways, basements |
| CDW High Head | 5–75 HP | 350–2,200 LPM | 140 M | Deep tunnels, mines, hydro power plants |
| CDW Ultra High Head | 50–120 HP | Up to 200 m³/h | 200 M | Major tunneling, deep mine drainage |
All CDW variants handle dirty/muddy water with solids up to 12 mm and SG up to 1.1, pH 5–8. For slurry above SG 1.1 or solids above 12 mm, move to the CSL Series. For higher surface-pump capacity up to 1,550+ HP, see the CAP Auto-Prime range.
The CNC Series is a compact, bottom-discharge non-clog submersible pump built to handle thick sludge, viscous mixes, and fibrous solids up to 70 mm in diameter — the category of liquid that blocks standard dewatering impellers within minutes. With a specific gravity rating up to 1.2, the CNC covers drainage applications where the liquid is heavier than clean water but not yet at true slurry densities: construction site sump desilting, manhole and stormwater pit cleaning, sewage bypass during STP maintenance, and trench drainage in clay-heavy soils.
The CNC's bottom-discharge configuration is critical for handling 70 mm solids — standard top-discharge submersibles cannot pass this particle size without clogging. The 14-inch compact body diameter fits directly into standard 14" manholes, making it the default choice for municipal contractors and EPC teams performing sewer bypass and stormwater rehabilitation.
Specifications: 6–20 HP · Flow rate 1,250–1,500 LPM · Shut-off head 22–30 M · 50 sq mm H07RNF heavy-duty cable (10 m) · SS-304 volute · Nitride-hardened SS-410 impellers (HRC 52–55) · Twin SS mechanical seals · Class H insulation (180°C) · Aluminium alloy lightweight design · Sacrificial zinc anode option for saline conditions.
For full technical specifications and discharge configurations, see the CNC Non-Clog Pump page.
The CSW Series is our high-capacity sewage submersible pump range, designed for municipal corporations, residential complexes, and industrial sewage networks handling liquid at specific gravity up to 1.7 with solids up to 100 mm. Spanning 2 HP to 200 HP and flow rates from 775 LPM to 33,000 LPM, the CSW covers the complete range from single-building sump applications through to main city sewage lift stations.
Municipal sewage imposes conditions that general-purpose dewatering pumps are not rated for: high SG liquids loaded with rag, fibrous material, and solids up to 100 mm that cause wrap-around and clogging in standard impeller designs. The CSW uses a channel or vortex impeller configuration optimised to pass these solids without hydraulic bridging, paired with F-class insulation (155°C) with a thermal sensor, dual TC vs TC mechanical seal and oil seal, and an SS-410 high-torsional-strength shaft that withstands shock loads from large solid impacts.
Key technical features: SS-316 lifting hook · Angular/radial/tapper ball bearings with high-temperature grease · Optional Class H insulation upgrade · Optional moisture and temperature sensor for remote monitoring. The CSW integrates directly with CosmoSmart™ IoT monitoring for remote running-data access, alarm management, and service scheduling.
For flow curves, auto-coupling options, and STP/ETP bypass configurations, see the CSW Sewage Pump page. For rental deployments during sewage rehabilitation, see our pump rental division.
The CSL Series is a dedicated submersible slurry pump engineered for the most abrasive pumping duties in the industrial and mining sectors: ash transfer at thermal power stations, silt and sand removal, coal runoff sump drainage, mine waste pumping, harbour and dredging construction, and any application where fluid solids content exceeds 70% by weight at specific gravities up to 2.1.
Standard pump components are destroyed by high-abrasion slurry in days. The CSL uses 27% hi-chrome white cast iron (WCI) construction for all wetted parts — a material with a surface hardness 4–5× greater than standard grey cast iron, rated specifically for abrasive mineral slurries. Flow rates range from 1,584 LPM to 5,834 LPM at shut-off heads of 27.5 M to 52.5 M, with HP ratings up to 100 HP.
The CSL-TV adds a twin-volute casing to the CSL hydraulic, which cancels the radial thrust force generated at off-BEP operating points. In continuous slurry duty — mine tailings sumps, flyash sluicing lines — radial thrust is the primary bearing-failure mechanism. The CSL-TV's twin-volute design extends bearing life significantly, reducing unplanned downtime on duty-critical slurry transfers where pump replacement mid-operation carries high project cost.
For full CSL and CSL-TV specifications including hi-chrome material certifications and slurry particle size compatibility charts, see the CSL Slurry Pump page.
The table below maps the six primary industrial sectors served by the submersible range to the recommended series, with the engineering rationale for each selection:
| Application Sector | Recommended Series | Engineering Rationale |
|---|---|---|
| Construction site dewatering | CDW Standard (1.5–50 HP) | Clean to muddy water, 12 mm solids, fast site setup; modular design repositions across sumps without crane |
| Mining & tunnel drainage | CDW High Head / Ultra High Head | High TDH requirements (40–200 M) for deep mine levels; CDW Ultra HH to 200 M for major tunneling contracts |
| Municipal sewage lifting | CSW (2–200 HP) | SG 1.7, 100 mm solids, continuous-duty rated; auto-coupling installation for permanent lift station mounting |
| Slurry, ash & mining process | CSL / CSL-TV | 27% hi-chrome WCI withstands SG 2.1 and high mineral abrasion; CSL-TV for duty-critical continuous operations |
| Non-clog drainage & bypass | CNC (6–20 HP) | 70 mm fibrous solids, bottom-discharge, 14" manhole-fit body; the standard for sewage bypass and stormwater pit desilting |
| Defence, border infrastructure & remote critical projects | CDW High Head | Compact sealed unit, no surface installation; reliable restart in power-restore cycles; sacrificial zinc anode for marine/high-humidity environments |
Follow these three steps to identify the correct submersible pump series, HP rating, and CDW sub-variant for any new application. For complex multi-pump systems or unusual liquid characteristics, use the iDEWA AI Advisor for an instant engineering-grade recommendation.
Measure or estimate the two critical liquid parameters:
Map your SG and solids to a series using this rule:
Once the series is selected, calculate the Total Dynamic Head (TDH) to determine HP and variant:
TDH (M) = (Hs + Hf + Hv) × 1.20
Once TDH is known, cross-reference with the required flow rate (LPM or m³/h) on the pump curve. For CDW, also use TDH to select the sub-variant: Standard (head ≤ 86.5 M), High Head (head 40–140 M), Ultra High Head (head 90–200 M).
Use the HP quick-reference table below. Select the row matching your confirmed series, then pick the HP rating whose duty-point flow (at your calculated TDH) meets or exceeds the required site flow rate. Always size to the duty point, not shut-off head — a pump operating at shut-off wastes energy and creates hydraulic heat.
| Series / Variant | HP Range | Max Flow Rate | Max Shut-Off Head | Liquid SG | Max Solids |
|---|---|---|---|---|---|
| CDW Standard | 1.5–50 HP | 8,500 LPM | 86.5 M | 1.1 | 12 mm |
| CDW High Head | 5–75 HP | 2,200 LPM | 140 M | 1.1 | 12 mm |
| CDW Ultra High Head | 50–120 HP | 200 m³/h | 200 M | 1.1 | 12 mm |
| CNC Non-Clog | 6–20 HP | 1,500 LPM | 30 M | 1.2 | 70 mm |
| CSW Sewage | 2–200 HP | 33,000 LPM | 60 M | 1.7 | 100 mm |
| CSL / CSL-TV Slurry | Up to 100 HP | 5,834 LPM | 52.5 M | 2.1 | 70 mm by wt. |
If your required flow rate or TDH falls outside the submersible envelope, consider the CAP Auto-Prime surface pump (up to 1,550+ HP, 74,483 LPM) or explore short-term rental options for peak-demand or monsoon-season dewatering.

A submersible pump is a centrifugal pump with a hermetically sealed motor, designed to operate while fully immersed in the liquid it is pumping. The sealed motor prevents water ingress, and the pump pushes fluid upward through a riser pipe or hose to the discharge point at the surface. Because the pump is submerged, it requires no priming, no foot valve, and no suction lift — the static head of the liquid above the pump inlet provides positive suction, eliminating vapour lock. Submersible pumps are used across construction, tunneling, mining, municipal, and industrial applications where the pump unit must be positioned at or below the liquid surface.
The CDW is a dewatering pump rated for dirty or muddy water with solids up to 12 mm and SG up to 1.1 — it is the correct choice for construction site drainage, mine sump dewatering, tunnel drainage, and foundation excavation pits. The CNC is a non-clog pump with a bottom-discharge design and a vortex/channel impeller that passes solids up to 70 mm at SG up to 1.2 — it is the correct choice for thick sludge, fibrous slurry, manhole and stormwater pit cleaning, and sewage bypass pumping during STP/ETP maintenance. Using a CDW in a 70 mm solids application will result in rapid impeller clogging; using a CNC for clean construction drainage introduces unnecessary cost. Match the series to the liquid type, not the project type.
A submersible pump must be positioned at or below the water surface and requires a constant electricity supply — it cannot run dry. A surface auto-prime pump is positioned above ground, requires suction lift (typically ≤8.5 M), can be engine-driven (suitable for sites with no grid power or intermittent supply), and can run dry without damage. Choose a submersible pump when the pump must be placed inside the sump, when multiple small sumps must be served simultaneously, or when the application involves sewage or slurry that cannot be lifted via suction. Choose the CAP Auto-Prime surface pump when suction lift is available, when a diesel engine is required, when portability across multiple site moves is needed, or when very high flow rates (above 8,500 LPM) are required from a single unit.
The operating depth of a submersible pump is limited by the motor cable length and the cable's pressure rating, not by the pump hydraulics. Standard CDW units ship with a 15 M waterproof PVC cable; the CDW Ultra High Head ships with a 20 M cable. These cable lengths cover the vast majority of construction sump and mine sump applications. For deployment at greater depths — deep shaft mining, hydro tunnels — extended cable options or in-sump electrical junction boxes with cable extensions are used. The maximum submersion depth is always specified per unit; confirm with the engineering team before deploying beyond the standard cable length.
Standard submersible dewatering pumps (CDW series) are not rated for slurry: the grey cast iron and aluminium alloy wetted parts are rapidly abraded by high-mineral-content fluids above SG 1.1. For true slurry applications — mine tailings, ash transfer, silt removal, sand and gravel pumping — the CSL Slurry Series uses 27% hi-chrome white cast iron (WCI) construction throughout the wetted path, which has surface hardness 4–5× greater than standard grey cast iron. For transitional sludge and thick viscous mixes (SG up to 1.2, 70 mm solids), the CNC Non-Clog is the intermediate option. Deploying a CDW in a CSL application will result in early wear-part failure and high total cost of ownership.
For standard construction dewatering duty (CDW series, clean to muddy water), inspect the mechanical seal, wear plate gap, and impeller clearance every 500 operating hours or at the end of each major project phase, whichever comes first. For non-clog (CNC) and sewage (CSW) applications handling fibrous and coarse solids, inspect every 250–350 hours due to higher wear rates on seals and impeller channels. For slurry duty (CSL), replace hi-chrome wear parts every 150–300 hours depending on particle hardness and SG — maintain a wear-part kit on site at all times. The CDW's adjustable wear plate gap (±5 mm) can restore hydraulic efficiency without removing the pump from service. For all series, motor winding insulation and cable integrity should be tested with a megger every 12 months or after any major submersion incident.
Cosmos Pumps is a trusted dewatering pump manufacturer in India with ISO & CE certification, manufacturing submersible dewatering pumps since 2021.
A submersible dewatering pump is an electrically-powered pump that operates fully submerged in water. Unlike surface pumps that draw water upward (losing energy to suction lift), a submersible dewatering pump pushes water upward from below — eliminating suction lift losses and allowing efficient pumping from deep sumps, tunnels, and flooded excavations.
Submersible dewatering pumps are the standard choice for construction site dewatering, mine water management, tunnel drainage, basement water removal, and emergency flood control in India. They are preferred over surface pumps when the pump must operate in water (no access to dry ground), when multiple sump locations are needed on a large site, or when grid power is available but space on the surface is constrained.
Cosmos Pumps manufactures the CDW series of submersible dewatering pumps in Faridabad, NCR — covering flow rates from 450 LPM to 8,500 LPM and heads from 15.5 M to 86.5 M. The CDW range is available from 1.5 HP to 50 HP and handles dirty/muddy water with suspended solids up to 12 mm.
A submersible dewatering pump works by drawing water into the pump body through a strainer, accelerating it through a rotating impeller, and discharging it upward through a delivery column or flexible hose to the surface. The motor and pump assembly are sealed as one waterproof unit — the motor is cooled by the water it is submerged in, which is why these pumps can run continuously without overheating.

| CDW Ultra High Head | 200 M | 50–200 m³/h | 50–120 HP | 12 mm | Major tunnel TBM drives, deep mines, large infra projects |
Water type handled: Dirty or muddy groundwater, construction runoff, and waterlogged soils with suspended solids up to 12 mm. Specific gravity up to 1.1. pH 5–8. Not suitable for raw sewage (use CSW) or slurry/ash (use CSL).
Saline/coastal applications: The CDW range is available with SS316 wetted parts and a sacrificial zinc anode option for seawater, brackish water, and coastal site groundwater. Specify SS316 variant at the time of enquiry.
At Cosmos Pumps, we understand that reliable pumping solutions are at the heart of smooth operations across industries. Water management, whether for construction sites, mining areas, municipal needs, or emergency situations, demands equipment that is not only efficient but also easy to handle. That is why we have engineered our range of portable submersible pumps to combine performance with convenience. Unlike traditional pumping systems, an electric submersible pump is designed to be placed directly in the fluid, eliminating priming issues and reducing energy loss. This makes them the preferred choice for dewatering and draining tasks where time and efficiency are critical.
Our submersible dewatering pump is designed to provide outstanding performance under challenging conditions. Our emphasis has been on the development of compact, portable yet powerful pumps that can be utilised in a broad spectrum of applications. Our product differentiation is also the attention to detail that can make our products durable and efficient.
Cosmos Pumps do not simply sell you a machine. You receive someone who is an expert in providing solutions to your pumping problems. Get to know our CDW Series and find out how our innovation will make a difference.
At Cosmos Pumps, we offer quality and all forms of submersible mud pumps. Our durable, efficient and portable solutions ensure high performance by focusing on industrial, municipal and construction applications.
The pump flow rate is the volume of fluid that a pump can move in a given time period. The Flow rate (Q) can be measured in various units like – cubic meter/hour (m3/h), litre/minute (l/m), or gallons per minute (GPM).
A submersible dewatering pump is a pump that operates entirely underwater to remove groundwater, rainwater, or floodwater from construction sites, mines, municipal sites, infrastructure projects, and basements. Unlike surface pumps, it works while fully submerged, making it efficient for rapid water evacuation without the need for priming.
The motor and pump are sealed in a single waterproof housing. When switched on, the motor drives an impeller that creates centrifugal force, drawing water in through the bottom inlet and pushing it upward through a discharge pipe to the surface. Because the pump is already surrounded by the fluid it is moving, there is no suction lift requirement and no risk of cavitation from a dry start — provided the motor has thermal protection.
Not all submersible pumps handle the same fluid. Cosmos Pumps manufactures four distinct ranges of submersible dewatering pumps to cover the full spectrum of site conditions:

Submersible sewage pumps handle soft solids and sludge in sewage water. It is perfect as far as municipal sewage systems, treatment plants and drainage systems are concerned.
The Pump head refers to the height that a pump can lift water. As the head increases, more water will reach a greater vertical distance because the pump can push it up. It is essential when choosing a submersible pump to consider applications in bottomless pits or high-rise buildings.
Delivery head refers to the vertical height between the pump outlet and the point of discharge. It can assist in acquiring the necessary pump capacity and energy consumption.
The pump flow rate is the quantity of water within a specific period; the rate is quantified in m 3 /hr, L/min, or GPM. Dewatering and mud pumps made and installed by us are available in several flow capacities.
It is an inverse relationship. When the flow increases, the head tends to decrease. The correct proportion would provide you with the best results with your pumping application.
