HydroForce Pumps Ltd has developed a clean water pump for rainwater harvesting tanks.
The pump features an alloy bulkhead, pressure release gap and patent-pending twin chamber design which prevents ingress of water to motor, electrical components and to bearing oil.
The Hydroforce pump is pressure sensitive, and turns itself off until there is a demand for water. If no water is detected for eight seconds the pump is turned off by a printed circuit board (PCB) to protect the motor and pump from burning out. There is an automatic re-set after a period of 30 minutes. If water is still not detected, the subsequent re-set periods are one and a half, three, seven, twelve and twenty-four hours and then back to the beginning of the cycle. Additionally, a thermal switch not connected to the PCB turns the pump off if the motor should overheat and re-sets when it’s cool again.
The pump comes with factory fitted filter, connectors and non-return valve.
The new pump can be fully immersed in tank water or it can be externally connected to the tank above ground. The pump will deliver up to 3.5 bar and delivers more than 2,500 litres per hour using a one-inch connector. Rated at 800w, on a 220v to 240v power supply, the pump is electronically controlled and features logic processors in the PCB.
