Centrifugal Pump

SB series centrifugal pump is the ideal equipment to provide impetus for Desander 、Desilter and Jet Mud Mixer for solids control equipment . Centrifugal pump is also called sand pump .DC produce the pump with reliability 、 heat-resistant 、large flow 、long life 、low- energy consumption 、easy maintenance and other advantages .

DC centrifugal Pump DC centrifugal Pump

The pump adopts the axial suction structure, horizontal or vertical structure, composed of a motor, a pump seat, a pump shell, an impeller etc., using shear coupling (horizontal pump) or plum coupling (vertical) connection, mechanical or combined sealing structure, the main vice impeller combination.

DC production of centrifugal pump is for oil field drilling fluid new supporting pump . The impeller is specially designed to have a wider flow pass and smooth vanes , with larger flow area and smooth fluid pass , making the pump efficiency and energy saving , 10 % higher than similar products .

1. Adopt international advanced level of high wear - resistant hard alloy mechanical seal , has a long service life . And auxiliary seal use packing seal , to prevent accidents .
2. Imported bearing ensure the centrifugal pump running time is long and stable running .
3. Bearing used lubricating oil and lubricating grease two lubricating ways , the service life is greatly lengthened .
4. Use more thick pump shell , passage shape is more reasonable , the turbulence is reduced to the minimum than conventional .
5. Pump body with open structure , installation , repair and maintenance more convenient .
6. Impeller 、flow components adopt high wear resistant cast iron , guarantee the abrasion , corrosion resistance , life is improves by 50% .
