AutoPrime Surface Pumps

The AutoPrime pump line is designed to provide excellent performance under all circumstances. To provide automatic 100% dry priming, the system consists of a vacuum pump and a priming tank unit. removes air from the suction pipe and initiates pumping, even at suction heights of up to 9.8 meters. The pump ranges for surface dewatering are intended for use in mining and construction, in the removal of floodwater, and in other municipal applications. These also include diesel dewatering pumps.

    Waste water and Unwanted water

  • Cosmos Pump manufactures which type of Pump?

    Centrifugal Pumps

  • What is Pump Head?

    A pump’s head is the maximum height in meters that the pump can achieve pumping against gravity. If a pump can produce more pressure, it can discharge the water higher and is said to have a “higher head”.

  • What is Delivery Head?

    Vertical Height from the Discharge point of the pump up to the final discharge point.

  • What is Pump Flow rate?

    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).

  • What is the relation between Head and Flow?

    The head of a pump is inversely proportional to the flow rate. It means as the Head increases the flow decreases and at one point it becomes zero – called shutoff head.

  • Can I get more than 1000 m3/hr flow rate in any of your pumps?

    Ofcourse, you can get more than 1000 m3/hr flow rate with cosmos pump.

  • What’s the warranty for the pumps?

    We offer warranty for 1 year period against manufacturing defect.

  • How will you carry out after sales support?

    Our technician will visit directly to your site/warehouse.

  • What is Suction head?

    Height between suction points of pump and water source level from where water is to be sucked.

  • What is Total Head?

    The sum of the Suction Head and Discharge Head.

  • What is Shut-off Head?

    It is the maximum head at which the pump will shut to perform.

  • What type of drive source is used in Auto-Prime/Self-prime pumps?

    Engine Coupled and Motor Coupled pumps

  • How often we need to drain the auto prime tank?
