KOS hydraulic piston pump is generally divided into single and double piston plunger, typical representatives of the four kinds of German Putzmeister solids pumps, which are: EKO single piston pump, KOS, KOV, HSP three kinds of double piston pump. The pump belongs to positive displacement pumps, especially for high solid content, long-distance pipeline conveying viscous material to repair the hydraulic motor, the advantage is to run very stable and reliable, but noisy, delivery pressures up 130Bar, the displacement of up to 0.5 to 500 cubic meters / hour. Widely used in sewage treatment, solid waste treatment, mining and metallurgy, dredging hydraulic motor for sale, dredging, petrochemical, power plants, cement industry and other fields. [Edit this paragraph] Piston - piston principle has been around for decades, its popularity depends on two main reasons: 1. They do not need external energy - the force of water they provide the The energy required. 2, their equipment is extremely simple, with only two moving parts. This design has more moving parts, but it can achieve the same functions of the hydraulic motor installation, and can be easily enlarged or reduced to any size. It can be seen from a long time ago the idea of ??the use of water energy! [Edit this paragraph] Piston - Advantages piston is reciprocated by the plunger seal volume caused by changes to achieve the pump suction and pressure oil, compared with gear pump and vane pump in the cylinder, this pump has many advantages.
