SHD-R 3000

Pressure-relief valve

Function

„The pressure-relief valve is an integrated solenoid valve.

„The pressure-relief valve is only active during the start-up phase when the system is configured for star-delta starting.

„When the pressure-relief valve is opened, the liquid delivered by the pump flows back to the suction side. As a result, no pressure is built up, and the load on the motor is reduced during the start-up phase.

Detergent metering at the suction side of the pump

Danger!

If the detergent reservoir is empty and the metering valve is open, the pump takes in air. This can lead to damage to the pump, therefore:

„check detergent reservoir regularly,

„do not open metering valve until actual work commences,

„close metering valve as soon as work has ended.

Function

„A diaphragm has been inserted into the pump intake connection,

„detergent is taken in from an external reservoir,

„the amount taken in is determined by a metering valve,

„metering is switched on or off by a solenoid valve.

Detergent metering at the pressure side of the pump

Function

„Detergents are taken in from an external reservoir and fed to the output from the pump,

„an injector mixes the detergent with the high-pressure jet (double spray lance required for detergent metering),

„detergents can also be metered by means of a high-pressure metering pump.
