Screw pump Series GRHigh performance pump series for industrial and marine applications Advantages The Parker screw pumps are dependable and economical low pressure pumps free from pulsations, ensuring a long service life and quiet operation. These rotary pumps with axial flow have only three moving parts and can be installed in any position, as well as above oil level. The secondary screws act as seals and are turned hydraulically by the fluid being pumped. There is only a rolling action between the main screw and the secondary screws, which eliminates noise and vibration Typical applications: - • Lube services (diesel engines, turbines, compressors, gears and gear boxes)
- • Seal oil services (compressors, generators)
- • Power hydraulics (presses, machine tools, working machines rolling mill, injection moulding machines, dumping equipment, elevators, variable pitch propellers, hydraulic winches)
- • Various and special applications for industrial and marine uses
