For information on pumps and details on pump terminology go to the bottom of this page.


  • TRANSFER PUMP – designed for movement of water from one source or location to another

  • TRASH PUMP – for moving water or slurry with debris in solution – for example stones, gravel, slurry, shells etc

  • DIAPHRAGM PUMP – for pumping of liquids where the pump may run dry without damage to the pump

  • CHEMICAL PUMP – for pumping chemicals, diesel fuels etc

  • FIRE FIGHTER PUMP – higher pressure pumps for greater head of pressure or for portable fire fighter units

  • SUCTION HEAD – is the vertical distance between the surface of the water & the water inlet point on the pump.

  • DISCHARGE HEAD – is the vertical distance from the pump outlet to the surface of the water at its discharge point

  • TOTAL HEAD – is suction head + discharge head

  • OUTPUT (max.) – the maximum discharged output of water (this is affected by length of hoses, total head, size of hoses)


Helpful Tips: 

  • Make sure you match the size of the pump you purchase to the size of the job and the size of the hosing. You can't run a 2" pump, for example with 1" hosing.

  • Use a strainer of filter or nylon stocking over the end of the pump hose inlet to reduce/prevent contaminated material from entering the pump

  • Never run a pump dry of water - this can damage or ruin the pump housing/impellor
