Water pumps move water that does not contain suspended solids or particulates. These pumps are not so much a type of pump as they are a classification based on the media being transferred. Nearly every pump type that is defined by either a complementary application (fountain water pumps, submersible water pumps) or by motive type (such as centrifugal, cantilever, or hand water pumps) can be used in water service applications. See the main Pumps page for links to pumps classified by motive force.

 

 

Applications

While slurries and the like are best handled by wastewater or sewage pumps, water pumps can handle ground water, potable water and salt water. Water pump applications include:

 

  • Water supply distribution
  • Irrigation
  • Land and mine drainage
  • Sea water desalination
  • Condensate transport
  • Sump and bilge pumping

Selection criteria Water Pumps

  • Specific application
  • Discharge flow and discharge pressure
  • Size of the inlet and outlets to which the pump connects
  • Temperature of the water to be pumped
  • Need to maintain some form of sterility
  • Power source
    • Electric pumps are available in AC and DC models.
    • Fuel-driven (gas, oil, diesel, etc.) pumps can generate high degrees of lift.
    • Solar pumps are useful in small flow situations, especially in applications that require remote placement, or in places where regular supervision is not available

Related Products & Services

  • Dosing Pumps

    Dosing pumps are low-volume fluid pumps with controllable discharge rates used to inject additives into the mixing or pumping system.

  • Gear Pumps

    Gear pumps use intermeshing gears to pump various types of liquids. Typically, one gear is the driver and the other is free wheeling. The gears have very tight tolerances so that the fluid being pumped cannot pass through them. Common uses for gear pumps include high pressure, metering, and flow control applications.

  • Magnetic Drive Pumps

    Magnetic drive pumps are sealless pumps that use a coaxial magnetic coupling to transmit torque to an impeller. A standard electric motor drives a set of permanent magnets that are mounted on a carrier or drive assembly.

  • Plastic Pumps

    Plastic pumps are designed to move fluids that would corrode or damage other types of pumps. They provide broad chemical resistance and are less costly and lighter in weight than metal pumps.

  • Positive Displacement Pumps

    Positive displacement pumps use a mechanical force such as gears, bladders, pistons, plungers or diaphragms to push liquid through and out of the pump.

  • Sanitary Pumps

    Sanitary pumps are used to transport and meter solutions, slurries, and colloids of food and agricultural materials in operations such as food processing that require cleanliness. There are four basic types of sanitary pumps: centrifugal, positive displacement, jet, and airlift.

  • Syringe Pumps

    Infusion or withdrawal syringe pumps provide high pressure and high accuracy for applications such as high performance liquid chromatography (HPLC).  Used to deliver precise amounts of fluid at specific time intervals.
