Inlet pressure

The maximum inlet pressure (see Technical data) is to be observed for the system configuration. The maximum permissible inlet pressure is calculated from the maximum operating pressure of the system minus the maximum pump delivery head at Q = 0

Pressure reducer

Should the inlet pressure be too high or fluctuate too greatly, a pressure reducer must be installed to guarantee a constant minimum inlet pressure. The inlet pressure may fluctuate no more than 1.0 bar

Volume flow

Up to 240 m³/h (66 l/s) system configuration according to DIN 1988 (EN 806); with standby pump up to 320 m³/h (88 l/s) in the event of operation of the pump as an additional peak-load unit

Residual-current devices

When installing residual-current-operated protection switches in conjunction with frequency converters, bear in mind that only universal-current-sensitive residual-current-operated protection switches in accordance with DIN/VDE 0664 are to be fitted.

Wilo-WMS low-water cut-out switchgear

According to DIN 1988 (EN 806), the installation of a low-water cut-out switchgear is required if the pressure boosting systems are connected directly to a public mains power supply; this prevents the inlet pressure in the mains supply line from dropping to values below 1.0 bar. Please order directly when ordering the pressure boosting system. The WMS will then be installed in the pressure boosting system, electrically wired and fully tested by Wilo during the final functional test.

Standards/directives
