WORKING PRINCIPLE
8This SINGLE VANE pump is designed fo automatic use (single phase). The principle is pump with a single vane impeller, which is mounted at the end of the drive shaft and enclosed in a large ring chamber, formed by the pump body and the base. The suction opening is in direct with th liquid to be pumped. The rotating impeller transmits kinetic energy to the liquid, which is centrifuged in the ring chamber, where part of the kinetic energy is transformed into pressure engergy. The particular shape of the impeller makes the optimized efficiency.

MAIN FEATURES
8Using Single(three) phase power source, it's complete stainless steel structure, rust free and anti corrosion vortex type or double-vane impeller features powerful sewage disposal capability.The maximum solid diameter of passage up to 50mm on request. It can be made of standard AISI SS 304 for common acid or alcali (PH value 4-10) or 316L for sea water or chemical industry (PH value 0-12).
