Clarke's ISP14A submersible water pump is powered by a heavy duty 1460 Watt electric motor, has a massive 410 litres per minute (maximum) water flow rate, & a float switch too! This automatically turns the pump on or off as the water level rises & falls. Perfect for industrial use, it drains not only clean water but brackish & dirty water too. & it's even powerful enough to pump sewage water as well, handling water containing solid bodies up to a maximum size of 50mm. It also benefits from many features for long term reliable service including having a stainless steel drive shaft, motor case, top cap & handle & base support with feet, also made from stainless steel. The pump body itself made from cast iron.
