A piston pump rotary group refers to the key component of a piston pump that is responsible for generating hydraulic pressure. It consists of a set of pistons (also known as plungers) arranged in a circular pattern within a cylinder block or barrel. These pistons are connected to a drive shaft and move in a reciprocating motion as the shaft rotates, creating pressure and pumping the hydraulic fluid.
The piston pump rotary group typically includes other important components such as valves, seals, and a swash plate. The valves control the flow of hydraulic fluid into and out of the pistons, while the seals prevent any leakage. The swash plate is an inclined disc that allows the pistons to move in and out as it tilts, adjusting the displacement and regulating the pump's output flow.
The rotary group is known as the heart of a piston pump as it is responsible for generating the hydraulic power required for various industrial and mobile applications. The design and arrangement of the pistons, valves, and swash plate can vary depending on the specific type and model of the piston pump.
We offer a wide range of Rotary groups especially for REXROTH pumps, some of them are listed bellow
