Liaocheng Yiheng Machinery Co.,Ltd

The rubber piston of the pump truck is the core sealing element of the concrete pumping system. The rubber piston has the dual functions of sealing and wear resistance. The rubber piston reciprocates in the concrete cylinder, withstands the high pressure environment of 5MPa, and resists the cutting wear of sand and stone in the concrete. Its lip structure needs to maintain elastic sealing to prevent slurry from penetrating into the hydraulic system. In terms of materials, we provide: rubber piston, cloth-reinforced rubber piston and polyurethane material piston. In terms of piston types, we provide split piston and integral piston
