3" ZEHNDER BOREHOLE PUMPS

The "TM" series submersible bore hole pumps from Zehnder are the ideal, perfect pump for water supplies from your well or cistern.
Being fully submersible, these electrical, multistage deep well pumps were specially developed for pumping to depths of 8.5 metres, where conventional garden pumps are not able to produce very high pressures at sufficient flow rate volumes and are most suitable for garden irrigation and domestic water supplies
Once installed frost-proof in the well our submersible water pumps are quiet in operation and require a mains electricity supply of 230V, single phase 50Hz only.
All parts of the pumps which come into contact with water are manufactured from non-corrosive materials. This guarantees a long service life without compromising water quality.
All pumps are supplied with 20 metre drop cable and starter panel which also contains the capacitor, the peak load controller (overload switch) and line switch.
Should you require longer cable lengths, we can supply individually suited and tested underwater cables as required.
The pumps can be supplied as a complete package with automatic controls and all necessary equipment pertaining to it.
