GN Solids control presents its Positive Displacement Pumps with the GNG Screw Pump series in its different presentations, depending on the work flow, we have them from 10 to 90 m3 / h and 4kW to 22kW. These positive displacement pumps are hydrostatic equipment. They pump a defined volume regardless of engine revolutions, but virtually independent of pressure. A positive displacement pump is one that displaces (delivers) the same amount of fluid for each rotation cycle of the pumping element.
These pumps are ideal for feeding centrifugal decanters without agitating the drilling mud. The main parts are the screw shaft (rotor) and the screw shaft bushing (stator). Due to the special geometric shape of the two parts, they form the pressurizing capacity separately. The fluids flow along with the shaft, the internal flow speed is slow, the capacity remains, the pressure is constant, so it will not generate vortices or agitation. The pump shaft is made of stainless steel, the GNG series pump is available for options with a full stainless steel body.
The GNG centrifugal feed pump can be driven by the coupler or adjust the speed using a variable speed motor, triangle V-belt, gearbox, etc. G series positive displacement pump with fewer accessories, compact structure, small volume, easy maintenance, rotor and Stator are wear parts of this pump, it is convenient to replace. The stator is made of elastomeric material, so it has particular advantages over other pumps for transferring fluids with high viscosity and included hard suspended particles.
Positive displacement pumps have multiple applications within the oil and gas industry, for the shipbuilding industry, beer industry, urban and wastewater treatment, paper industry, chemical industry, pharmaceutical industry, food industry, etc.
