Chemical pumps are widely used in industry, city water supply, drainage, can be used for farmland, orchard irrigation, for the transport of water or similar physical and chemical properties of water and other liquids used. Chemical pump and operation pressure head, vice impeller produced by high pressure liquid balance exports the main impeller, so as to realize the sealing. When parking, the Deputy impeller does not work, must therefore may produce chemical pump equipped with parking sealing device to solve the parking when leakage.
Vice impeller seal has the advantages of simple structure, reliable sealing, long service life, can be realized leak chemical pump operation, therefore the chemical pump is often used with impurity medium pump.
On the basis of chemical pumps for different purposes, there are several classification:
1) process: including feeding pump, pump reflux pump, circulating pump, flushing pump, sewage pump, pump, pump output of.
2) utility: pump including boiler pump, cooling tower, water pump, fire pump for deep well pump.
3) use auxiliary pump: including lubricating oil pump, seal oil pump, hydraulic transmission pump etc..
4) pipeline pump: oil pipeline pumps, pump trucks.
