The purpose of a water pump is to move water not containing suspended solids or particulates. Water pumps handle ground water, potable and salt water. High Pressure water pumps are widely used in water jetting applications.
Water jetting and water blasting equipment using high pressure water pumps is used to direct high pressure water streams against material to clean or cut it. The streams of water released by water jetting and water blasting equipment is normally 344 pressure to 2750 (5,000 psi to 40,000 psi). In an efficient water jetting system, pressure is vital consideration. Typically, hardened deposits respond better with high pressure water pumps, and softer materials are best removed with lower flows.
Water jetting and water blasting equipment is used for cleaning or demolition of products made of metal, wood, concrete, stone, plastic, glass or other building materials.
Specific components within a water jetting system include abrasive injectors, pressure generators, blast cabinets or booths, water guns, and water tanks. Abrasive injectors can convert a water jetting system into an abrasive blaster. The injection or metering system controls the amount of abrasive pushed into the air stream. In large systems, the delivery system and injection system may be separate components. Pressure generators increase the pressure of the carrier fluid (water or air). Plunger-type intensifier pumps are commonly used to generate high pressure water for water jet cutting, wet or water abrasive blasting and non-abrasive pressure washing or rinsing.
