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
The overall system conforms with the requirements of
- DIN 1988 Part 5
- DIN 1988 Part 6* (**)
* The specifications in DIN 1988 (EN 806) and of the water-supply companies are to be observed. Regarding the electrical components, the system conforms with the requirements of
- VDE 0100 Part 430/Part 540
- VDE 0110 Part 1/Part 2
- VDE 0660 Part 101/Part 107 and
- DIN 40719/IEC 754
Always observe the specifications in DIN 1988 (EN 806) when using and operating the pressure boosting system.(**) That does not apply to fire extinguishing systems in accordance with DIN 14462. Please request these separately.
