The Hydraulic Piston Pump
The hydraulic piston pump or solid pump is driven by the hydraulic power pack, and the hydraulic cylinder pushes the conveying cylinder to output the material in the conveying cylinder to the pipeline. It is generally divided into single plunger and double plunger. Typical representatives include four solid pumps of German putzmeister company, which are EKO single plunger pump, KOS, KOV and HSP double plunger pump. This pump is a volumetric pump, which is especially suitable for long distance pipeline transportation of viscous materials with high solidity. Its advantages are very stable and reliable operation, but large noise, the conveying pressure can be up to 130Bar, and the discharge capacity can be up to 0.5-500 cubic meters per hour. It is widely used in sewage treatment, solid waste treatment, mine metallurgy, dredging, petrochemical, power plant, cement industry and other fields.
