Some tips to make the right choice

Real flow rate of the water supply network

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

Temperature of the HP washer according to its use

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.
