About CAT pumps

CAT Pumps make high pressure plunger and piston pumps with flows from about 4 to 900 litres per minute and pressures from about 7 to 690 bar (1 to 240 US gallons per minute, 100 to 10,000 psi). They are built to be serviced, so worn seals, valves and plungers can be replaced to keep a pump running for many years.

Where CAT pumps are used

  • Pressure washing and commercial cleaning
  • Vehicle cleaning
  • Agriculture
  • Food processing and manufacturing
  • Misting, cooling and fogging
  • Reverse osmosis
  • Hydro excavation
  • Oil and gas
