BOSCH AQUATAK

With the pressure washer connected to the mains supply water enters the inlet

The motor drives a swash plate, which is connected to pistons in the pump housing

Note: This diagram shows an induction motor which rotates at 2800 rpm approx (fitted to Aquatak 1200 plus/1250/1350/1500)
The Series motor which rotates at 17,000 rpm has a reduction gear which reduces the rpm, not shown (fitted to Aquatak100/100 plus/110/110plus/115)


Stage 2 : Water being pumped created - pressure
The rotation of the swash plate causes the the pistons to move back and forth.
This causes the pistons to draw the water from the inlet into the chambers, and to create high pressure within the chambers

The inlet valve onlys allows the water to travel in one direction
Note : This diagram only shows one piston and one chamber, the pump head has three pistons and three chambers

Stage 3 : Water out at high pressure

The pressure produced by the three pistons forces the water out of the chamber and past the outlet valve

The water then travels through the high pressure hose towards the lance (not shown)
