China PV90R130 SAUER 90 Hydraulic Replacement Spare Parts | Partsdic®

The PV90R130 belongs to the Sauer 90 series of axial piston pumps.

It is renowned for its robust design and high-performance capabilities. This pump is known for its exceptional efficiency, reliability, and longevity, making it a preferred choice in demanding hydraulic systems.

One of the key specifications of the PV90R130 is its displacement. It is essential to know the displacement value to select the appropriate replacement spare parts. Displacement refers to the volume of hydraulic fluid the pump can deliver per revolution. In the case of the PV90R130, it typically has a displacement of 130 cc (cubic centimeters) per revolution. However, it's crucial to check the specific model and version to confirm this value, as variations might exist.

The PV90R130 operates on the axial piston principle, where a set of pistons within the pump's housing reciprocate in response to the rotation of the drive shaft. These pistons are arranged in a radial pattern, and their movement generates the flow of hydraulic fluid. Each piston is fitted with a swashplate mechanism, allowing for variable displacement, which means it can adapt to the system's demand for flow and pressure.

Piston and Cylinder Block Assembly: The heart of the hydraulic pump, comprising the pistons, cylinder block, and swashplate. Over time, these components may wear out and require replacement.

Bearings and Seals: Bearings support the rotating components within the pump, ensuring smooth operation.

Seals are critical for preventing leaks and maintaining the pump's efficiency.

Valve Plates: Valve plates control the flow of hydraulic fluid within the pump. They can wear down due to constant movement and pressure, necessitating replacement.

Shaft and Drive Components: The drive shaft transmits power from the prime mover to the pump. Replacement shafts and drive components may be necessary if these parts become damaged.

Housing and Casings: The outer housing and casings protect the internal components of the pump. Damage or corrosion may require their replacement.

Control Mechanisms: The PV90R130 may have control mechanisms like pressure compensators or load-sensing devices. These components may also require replacement or adjustment.

Hydraulic Fluid Filters: Proper filtration is crucial to maintain the cleanliness of the hydraulic fluid. Regularly replacing filters is essential to prevent contamination.
