Tips: Advantages of electric operated diaphragm pump
- There is no need for water filling or diversion, and itself-priming capacity is above 5m.
- lts traffic ability is good, and those grains, slurry or others with a diameter less than 5mm can all be passed easily.
- The diaphragm will be separated by the working medium and the transmission machinery, so the medium can by no means leak outwards. Besides, the pump itself has no shaft seal, so its service life is extended greatly. According to different medium types, the diaphragm can be divided into neoprene, fluorine rubber, and so on, which can meet requirements of different users completely.
- Compact and light: with a planetary cycloid transmission structure, the pump can be small-size, and compared with similar pump types, both of its volume and weight are half or so.
1 inch electric operated diaphragm pump can be used for pumping high viscosity fluids and slurry, driven by 380V motor, 1.5kW, speed ratio 1:17, selectable body material of polypropylene, aluminum alloy, stainless steel and cast iron, working temperature up to 100℃.
