Some tips to make the right choice

For a 20 l/mn flow rate, i.e 1 200 l/h, it is advisable to have a real flow rate 20 to 30 % higher than the pump’s flow rate.

Section of the low pressure water supply hose :

For flow rates of 20 litres -> ø 19 inner diameter, 20 to 25 metres max.

For flow rates from 25 to 30 litres -> ø 25 inner diameter, 20 to 25 metres max.

*The thermal magnetic circuit breaker of your electrical installation must have a D type instantaneous tripping current.

Use of an extension cable : always completely uncoil the cable

For 13 usable amperes : 2,5 mm2 max. 35 metres < 4 mm2 < 4 mm2

For 16 usable amperes : 4 mm2 max. 35 metres < 6 mm2

For 20 usable amperes : 4 mm2 max. 25 metres < 6 mm2

For 23-25 usable amperes : 6 mm2 max. 35 metres < 10 mm2

After releasing the trigger of the HP washer, the water temperature increases quickly, which can lead to overheating of the pump.

All our HP washers accept water at a maximum temperature of 60°C.
