The concept of hydraulic piston pump

hydraulic piston pump or solids pumps, hydraulic power pack to drive the hydraulic cylinders, hydraulic cylinders advance the delivery cylinder, the delivery of materials to pipe the output of the cylinder. Generally divided into single and double piston plunger, typical representatives of the four kinds of German Putzmeister solids pumps, which are: EKO single piston, KOS, KOV, HSP three kinds of double-piston pump. The pump belongs to positive displacement pumps, especially for high solid content, long distance pipeline viscous material, the advantage is to run very stable and reliable, but noisy, delivery pressures up 130Bar, displacement of up to 0.5 to 500 cubic meters / hour. Widely used in sewage treatment, solid waste treatment, mining and metallurgy, dredging, dredging, petrochemical, power plants, cement industry and other fields.
manual gas pump: The engine crankshaft via two belt-driven air pump, which drives the piston pump, hit the gas through a pipeline to import gas cylinder.
