HRM pump

Three-piston swashplate pump in stainless steel with hardened stainless steel pistons. Double gasket sealing system. Pump head in stamped brass. Automatic bypass valve with pump head pressure relief. Single-phase induction electric motor.
Self-priming function
A self-priming pump is designed to draw water from an external source (such as a tank, drum, or container) without requiring water to be forced into the pump by initial pressure. This makes the pressure washer more versatile, allowing it to operate even without a direct connection to a pressurized water supply, such as when a tap isn't available, or to use alternative water sources such as tanks and wells.
