Centrifugal Pump for Drilling Fluid

1. Usage and Application Range

SB 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.

The SB10×8×14 centrifugal sand pump applies to over 3000-meter-long drilling rigs，with big viscosity and specific gravity drilling fluid.The SB8×6×14 centrifugal sand pmp applies to over 3000-meter-long drilling rigs.The SB8×6×11 centrifugal sand pump applies to under 3000-meter-long drilling rigs,also can be can be used to supply mud to triplex mud pump as a filling pump.The SB6×5×11 centrifugal sand pump applies to truck-mounted drilling rigs or pocket drilling rigs.The SB4×3 centrifugal sand pump is usually used as measuring pump or replenishment pump.The SB3×2 centrifugal sand pump is usually used as clean water pump.

2. Pump Features 

The Series Centrifugal Sand Pump has these features:

(1) Open impeller,apply to transport high viscosity drilling liquid.

(2) Combination seal for a long service life.

(3) Use universal bearing houses and bearings,convenient to maintain and cut the costs.

(4) The major parts are made from antiwear nodular iron,and long service life.

The prinple is that under the motor, the impellers of the pump rotate at high speed, the dring 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.
