Properties:
The pump is suitable for pumping large volumes of groundwater and surface water seepage in conjunction with large heads of polluted water from seepage wells. |
Thanks to its compact design, the pump is suitable for both mobile use and permanent installation. |
Made of grey cast iron, the pump has a vertical discharge and an integrated, fully enclosed three-phase submersible motor of thermal class F (155 °C). |
The pump is equipped with a riser, a cooling jacket for continuous cooling of the motor by the pumped liquid and a closed impeller to achieve high efficiency. |
The pump has a double mechanical seal and also a lip seal that protects the shaft and mechanical seal from abrasive components. |
The pump has a bimetallic temperature sensor to protect the motor from overheating and an electrode sensor to detect water ingress into the motor housing. |
The cable seal consists of a rubber bushing and a cover made of rubber and epoxy, thus preventing water from entering the motor. |
