Sany plunger cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and makes swinging motion. It has simple structure and reliable operation, and it is important parts for concrete pump.
Sany plunger cylinder is made of #45 Steel, which have higher strength and deformation resistance.
