Mud Sand Pump/Centrifugal Pump
 
LFSB  series  centrifugal  sand  pump  mainly  supplies  to  solids  control  circulating system of oilfield drill rig,and be used to provide drilling liquid with a certain discharge capacity and pressure to sand, desilter and mud mixer, to assure these equipment work efficiently.
 
Centrifugal Sand Pump Features:
Open impeller,apply to transport high viscosity drilling liquid.
Combination seal for a long service life.
Use universal bearing houses and bearings,convenient to maintain and cut the costs.
The major parts are made from anti-wear nodular iron,and long service life.
 
The principle is that under the motor, the impellers of the pump rotate at high speed, the drilling fluid is sucked into the suction pipe. After the drilling fluid flows through the suction pipe and gets enough energy and velocity under the centrifugal force, the drilling fluid is expelled continuously out of the pump.
