General Plunger Pump

These include de-scaling, quenching, water-blasting, concrete demolition, chemical dosing, hydrostatic testing, boiler feed, CO2 injection, abrasive wet blasting, and descalination by reverse osmosis.

The robust and popular Crown 350HP plunger pump is widely used in stope-washing applications and as a micro-power source for water rockdrills. This particular range of pumps is available in either the dry-shutoff variant to deliver very large water savings, or as a conventional dumping variant. Models are available with pressures of up to 20 MPa and flows of 220 litres per minute.
