Housing and Flange:
The pump's housing and flange are made of high-quality cast iron or steel, ensuring robustness and resistance to external stresses.
They provide a rigid structure for the internal components and ensure proper alignment during operation.
The cylinder block houses the pistons and swash plate mechanism. It is precision-machined to tight tolerances for smooth piston movement and efficient hydraulic flow. The cylinder block is typically made of high-strength steel to withstand high-pressure operation.
The SAUER PV Series features multiple pistons that reciprocate within the cylinder block. These pistons are designed to provide precise displacement and smooth operation. They are often made of high-strength materials with advanced surface coatings to reduce friction and wear.
The swash plate converts the rotating motion of the drive shaft into reciprocating motion of the pistons. It is mounted at an angle to control the piston stroke and displacement volume. The swash plate is typically made of hardened steel or cast iron for durability.
The valve plate is responsible for controlling the flow of hydraulic fluid into and out of the pistons. It contains a series of valves and ports that direct the fluid according to the pump's operational mode. The valve plate is precisely machined and often made of hardened steel to ensure reliable sealing and minimize internal leakage.
The drive shaft transmits the rotational force from an external power source to the swash plate. It is usually made of hardened steel to handle the torque and stress generated during operation. The drive shaft is supported by bearings to reduce friction and ensure smooth rotation.
Bearings play a crucial role in the pump's performance and longevity. They support the rotating components such as the drive shaft and swash plate, minimizing friction and enabling smooth operation. High-quality, precision bearings are used in the SAUER PV Series to ensure reliability and extend the pump's service life.
The shaft seal prevents hydraulic fluid leakage along the drive shaft.
It is typically a combination of seals, O-rings, and gaskets that create a reliable barrier between the internal and external environments. The shaft seal is designed to withstand high pressures and temperatures, ensuring a tight seal throughout the pump's operational range.
The SAUER PV Series pumps can be equipped with various control systems, including manual, hydraulic, or electronic control options. These systems allow precise control of the pump's displacement, pressure, and operational modes, making them suitable for a wide range of applications.
The SAUER PV Series offers versatile mounting options to accommodate different installation requirements. The pumps can be flange-mounted, foot-mounted, or directly mounted to the power source or hydraulic system, providing flexibility for integration into various equipment and machinery.
