 Part I :GNG Centrifuge Feed Pump

  ( Positive Displacement Pump)

GNG Series Centrifuge feed pump is a positive displacement pump, also called screw pump. The GNG positive displacement pump is an ideal pump for feeding to decanter centrifuge without shearing or agitating the drilling mud. The main parts are screw shaft (rotor) and screw shaft bushing (stator). Because of the special geometry shape of the two parts, they form pressurize capacity separately. The fluids flow along with the shaft, inner flow speed is slow, capacity remains, pressure is steady, so it will not generate vortex and agitating.The shaft of the pump is made from Stainless steel, GNG series pump is available for option with complete stainless steel body.

Features of GNG Centrifuge Feed Pump

GNG centrifuge feed pump can drive by coupler, or adjust the speed by using variable speed motor, Triangle V-belt, gear box,etc G series positive displacement pump iswith less accessories, compact structure, small volume, easy maintenance, rotor and stator are wear parts of this pump, it is convenient to replace. The stator is madeof elastomeric material, so it has particular advantages than other pump to transfer the fluids With high viscosity and hard suspended particles included.

Other Centrifuge feed pump

GNG Series Positive Displacement Pump is the most popular centrifuge feeding pump, but for some applications, drilling industry also use the horizontal centrifugal pump and submersible slurry pump to feed drilling mud to the decanter centrifuge.

 Part II:YZ Centrifuge Feed Pump

  ( Submersible Slurry Pump)

YZ Submersible slurry pump is with structure of vertical single stage and single suction system overhung centrifugal pump,it is made of abrasion-resistant alloy,it canconvey medium with high concentration particle.There is no bearing and Gland Seal between impeller and pump body,so the slurry pump is maintenance-free and high temperature resistance,the slurry pump is the ideal centrifugal pump for

Slurry Pump Model Meaning: 80-YZ80-20A
YZ  - Vertical Submersislbe slurry pump
80 – Pump outlet diameter (mm)
80–Pump design flow rate (m ³ / h)
20 –Pump design head (m)
A –Impeller first to be cut less

Pump's drive type: The slurry pump is connecting through the flexible coupling and the electric motor, the pump direction of rotation is clockwise from the prime move

YZ Submersible slurry pump structure

YZ Slurry  Pump is the cantilever pump structure of single stage and single suction, with the bearing housing, supporting, intermediate pipe connecting the  pump hydraulic components, the water is discharged out from the drain pipe parts, pump impeller is for semi-shrouded with the agitating vane on the vane extended, the main characteristic of this pump is the underwater pump shaft parts have enough rigidity, the impeller and pump shell have no bearings, no shaft seal, which can transport the greater medium of solid particles. The length of inserting the water by slurry pump is between 800 and 2000, the suction pipe can be matched in case of need. The shaft seal runs into the underwater pump without setting up the shaft seal, drive should be installed the vertical motor on the supporting seat connecting with coupling and pump.
