In this article, we will mainly introduce the Screw Pump that manufactured by GN Solids Control.
Screw Pump
As what showed in below picture, GN could manufacture and provide the Screw Pump from 4Kw to 22Kw, the pump flow is from 10m³/h to 90m³/h.

The GNG series Screw Pump is the ideal pump for feeding the decanter centrifuge.

As we know, the Decanter Centrifuge is usually used for separating the very fine solid particles in the drilling fluid, the drilling fluid will not be sheared and agitated by using the Screw Pump to feed the Decanter Centrifuge, so the separation effect could be better, which is related with the special structure and working principle.

Screw Pump

1.Working Principle of GNG series Screw Pump
The Screw Pump is mainly composed of 2 parts: the screw shaft (rotor) and shaft bushing (stator).
The motor drives the “rotor” to rotate, the drilling fluid flows along with the “rotor”. The rotation speed is low and the capacity of each helical cavity is same, which ensure the low flow speed and the fluid pressure is constant and there is no vortex and agitation with the drilling fluid. That is also why the Screw Pump is the ideal pump for feeding the Decanter Centrifuge.

2. Features & Advantages of GNG series Screw Pump
1). The Shaft Bushing (stator) is made of elastomeric material, so it has the particular advantage than other pumps to transfer the drilling fluids with high viscosity or hard suspended particles included.
2). As the wearing parts, the Screw Shaft (rotor) and “Shaft Bushing” is convenient for replacement;
3). Less accessories, compact structure, small volume, easy maintenance;
4). The Screw Pump could be driven by using the coupler, variable speed motor, V-belt, gearbox, etc.
5). There are different Explosion Standards with the motors & electrical control panel, such as EXdⅡBt4, IECEX, ATEX that could meet different customer options;
