JOHNTECH CPM & CPW Series – Single Stage Centrifugal Pump

Non self-priming pumps
The JOHNTECH CPM and CPW Series – Peripheral Pumps are non-self-priming units and the suction point of the pumps must always be installed below the water level of the tank. The pump must be installed on a flat surface that would not flood in heavy rain. The JOHNTECH CPM and CPW Series – Peripheral Pumps are especially designed for domestic use on rainwater harvest tanks, small to medium garden irrigation systems, long distance water transfers, heating ventilation and air-conditioning systems, pressure boosting water pipe systems and urban water supply systems.
