Shop PM Putzmeister Concrete Pump Hydraulic Main Piston Pump A4VG125 Replace Parts Rotating Group | Tonkee®

The rotating group in the A4VG125 pump is comprised of various components working in tandem to ensure the smooth and consistent operation of the hydraulic system.

These components include the swashplate, pistons, cylinder block, valve plate, and bearings. Each element within the rotating group is carefully engineered to withstand the demanding conditions encountered in concrete pumping applications.

The swashplate is a fundamental part of the rotating group, responsible for controlling the axial movement of the pistons. It adjusts the displacement of the pump, regulating the flow of hydraulic fluid based on the system's requirements. The design of the swashplate in the A4VG125 pump is precision-engineered to provide optimal control and responsiveness, contributing to the pump's overall efficiency.

Pistons are another critical component within the rotating group, as they are directly responsible for pressurizing the hydraulic fluid. The A4VG125 pump is equipped with high-quality pistons that are durable and capable of withstanding the repetitive and intense forces associated with concrete pumping. These pistons ensure a reliable and consistent flow of hydraulic fluid, contributing to the pump's ability to handle the demanding nature of concrete pumping applications.

The cylinder block in the rotating group is designed to house the pistons and facilitate their reciprocating motion.

It is crafted from materials that offer both strength and durability, ensuring longevity even in challenging operational environments. The precision machining of the cylinder block in the A4VG125 pump contributes to the overall efficiency and reliability of the hydraulic system.

The valve plate is a critical element that controls the flow of hydraulic fluid to and from the pistons. It is designed with precision to maintain proper timing and synchronization of the pumping process. The A4VG125 pump's valve plate is engineered to minimize friction and wear, ensuring consistent performance over an extended operational lifespan.

Bearings within the rotating group play a vital role in supporting the moving parts, reducing friction, and enhancing the overall efficiency of the pump. The A4VG125 pump incorporates high-quality bearings that are selected for their durability and ability to withstand the dynamic forces present in concrete pumping applications.
