1. Usage and Application  Range

JSB 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 equipments work efficiently.

The JSB10×8×14 centrifugal sand pump applies to over 3000-meter-long drilling rigs,，with big viscosity and specific gravity drilling fluid.The JSB8×6×14 centrifugal sand pmp applies to over 3000-meter-long drilling rigs.The JSB8×6×11 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 JSB6×5×11 centrifugal sand pump applies to truck-mounted drilling rigs or pocket drilling rigs.The JSB4×3 centrifugal sand pump is usually used as measuring pump or replenishment pump.The JSB3×2 centrifugal sand pump is usually used as clean water pump.

2. Main Structure ,Feature

Its main parts are pump shell, impellers, bearing block, pump axle, bearing, shaft coupling,wearing plate, seal apparatus, oil seal, motor and base.

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
