ZM 44 – The lightest of the market!
The ZM range piston pumps has 5 sizes in the range. The smallest pump will operate at minimum flow of 2l/sec and push a head of 30m. These pumps delivery will be determined by the size of the wheel, the water flow driving the wheel and the head that needs to be pushed. Pumps can push up to 12km and do a head of up to 200 meter. The wheel comes in 1m, 1.4m, 1.8m and 2meter.
Production base on the RPM and the stroke of the pump
