Housing: The housing of the PV90R Series is constructed from high-strength cast iron or aluminum alloy, ensuring durability and resistance to harsh operating conditions.
The housing encloses and protects the internal components of the pump.
Cylinder Block: The cylinder block is a critical component responsible for converting hydraulic energy into mechanical energy. It contains multiple pistons arranged in a circular pattern. As the pistons reciprocate, they create a pumping action.
Pistons: The PV90R Series features precision-machined pistons that move back and forth within the cylinder block. These pistons are designed to withstand high pressures and provide efficient fluid displacement.
Valve Plate: The valve plate is positioned between the cylinder block and the swashplate assembly. It contains a series of valves that control the flow of hydraulic fluid to and from the pistons. The valve plate plays a crucial role in regulating the direction and magnitude of fluid flow.
Swashplate Assembly: The swashplate assembly consists of a swashplate and a control mechanism. The swashplate is mounted at an angle to the driveshaft and converts the linear motion of the pistons into a rotating motion. The control mechanism adjusts the swashplate angle, allowing for variable displacement and flow control.
Drive Shaft: The drive shaft transmits torque from the pump to the driven equipment. It connects the swashplate assembly to the external load and ensures the transfer of rotational power.
Bearings: The PV90R Series incorporates high-quality bearings to support the rotating components and minimize frictional losses. These bearings provide smooth operation and extend the overall lifespan of the pump.
Shaft Seal: The shaft seal prevents hydraulic fluid from leaking along the driveshaft.
It ensures that the internal components are properly lubricated and protected from external contaminants.
Port Plate: The port plate contains inlet and outlet ports for hydraulic fluid. It connects the pump to the hydraulic system, allowing for the intake of fluid and the discharge of pressurized fluid.
Control Options: The PV90R Series offers various control options, including manual, hydraulic, and electronic control. These options enable precise speed and torque control, making the pump suitable for a wide range of applications.
Accessories: SAUER provides a range of accessories and optional features for the PV90R Series, including pressure relief valves, case drains, and auxiliary flushing valves. These accessories enhance the performance, safety, and reliability of the pump.
