Above ground solar pump
The HD50 centrifugal solar pump is made of stainless steel with a plastic impeller. Centrifugal pumps are good when pumping clean water or water with a little fine sand. The pump rotates at a variable speed so that all the power available from the solar panels is used. It is equipped with a flow switch, pipe fittings, and foot or check valve. The motor is a high tech DC step motor which has no brushes, no wireless interference, a permanent magnet rotor and a built-in control circuit. It should be housed under cover from the weather and ventilated. It operates on 36 volts DC and uses about 10-15 amps. Top speed is limited. Step motors are very efficient and normally supply more water from the solar panels than other motors. The HD50 pump is a shallow well pump which means it's maximum suction at sea level is about 6 meters.
