On the basis to refer to characteristics of foreign advanced centrifugal pump, combined with the development requirement of concerned industries in the country, NJB serial consistency pump is the centrifugal pump to transport the media with a certain of impurities which is co-developed by our company and domestic famous experts of fluidics. All parts of the pump contacting with materials have corrosiveness and are made of stainless steel and are in conformity with conditions of foodstuff hygiene therefore the pump can be widely used in alcohol, starch, paper-making, foodstuff and chemical industries. It has main characteristics as follows:

1. Adopted open-style vane to avoid blockage, both front and rear doors make maintenance easily;
2. Adopted splash lubricating and circulated water cooling so service life of bearings are largely extended;
3. Adopted ceramic/mechanical sealing and combined with circulated water cooling, the pump can operate successively without leakage;
4. Adopted sub-vane to reduce pressure of axle sealing and prevent leakage due to invasion of impurities.
