the series pump is wet runner motor pump integrated the pump and motor, the impeller and the rotor is canned by cartridge and isolated from the stator. No mechanical seal used and only sealed by two gaskets. Bearings are lubricated by transferring liquid and motor is cooled by transferring liquid too. No leakage and low noise are two distinctive advantages for wet runner canned motor pump.


The circulation pumps are characterised by

1. Ceramic shaft and radical ceramic bearings
2. Carbon thrust bearing
3. Stainless steel rotor cartridge and bearing flange
4. Corrosion-resistant plastic impeller
5. Cataphoresis cast iron or engineering plastic pump housing

Motor insulation class H and integrated with thermal protector; Three speed selection motor; Terminal box position: 3h/6h/9h/12h easy for different installation ways. Easy-open terminal box with cable gland for easy electrical connection and keep sealing.
