25 Wire clamps Two units are needed per loop. This means per installation 4 wire clamps are recommended. Filters 1. Motor side (only for 3”WPS®-CP): When the drop cable between the controller and the pump exceeds more than 100m, an extra filter to protect the motor from burning is required. 2. Supply side (for both 3”WPS®-CP and 3”WPS® pumps) : Radio frequency interference is the radiation or conduction of radio frequency energy (or electronic noise) produced by electrical and electronic devices at levels that interfere with the operation of adjacent equipment. In case you experience phenomena, please install the WPS® RFI Power Line Filter. Cooling Shrouds The cooling shrouds are designed to ensure a sufficient flow velocity past the motor in order to provide sufficient cooling. For the following cases a cooling shroud is recommended: • horizontal or vertical installation in a tank • installation of the pump in the screen from the well • installation in big sized well not ensuring enough cooling velocity. See table. To the shroud itself, a screen can be added. In case of horizontal installation a set of supports are available. The screen can be changed by an adaptor with floating screen ensuring water intake about 20cm under the water level and prevent clogging of the pump due to sand or other sediments on the bottom of the tank, lake, … Material Diameter Reference Stainless steel DIN W.-Nr. 1.4401, Aisi 316 Ø 3 mm 71103 Description Max. length drop cable Reference WPS® 200MF Filter 200 m 7200 WPS® 400MF Filter 400 m 7210 Description Reference WPS® RFI Power Line Filter 7220 Minimum flow required for motor cooling in water up to 20°C.
