Single-phase induction electric motor
The single-phase induction electric motor with thermal protection releases a power of up to 2.5 kW , with a maximum flow rate of 500 l/h and a maximum pressure of 150 bar .
HPV-O pump

3-piston pump in tempered stainless steel with ceramic coating, connecting rod/crank system and brass head . Safety valve with pump head pressure reset , single-phase induction electric motor with thermal protection and remote total shutdown system of the pressure washer. Water intake from tank with self-priming function.


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.
