Housing: The pump's housing is made from high-quality cast iron or aluminum alloy, providing durability and resistance to wear.
It is designed to withstand high-pressure conditions and offers excellent heat dissipation.
Drive Shaft: The drive shaft connects the pump to the power source and transfers rotational motion. It is precision machined and made from hardened steel to ensure reliable performance and long service life.
Piston Assembly: The A20VO series utilizes an axial piston design. It consists of several pistons that move in and out within the cylinder block to generate hydraulic flow. These pistons are made from high-strength steel and are precision-ground for smooth operation and minimal friction.
Cylinder Block: The cylinder block houses the pistons and guides their movement. It is made from high-grade cast iron or steel and is designed to withstand high-pressure conditions. The block is precisely honed to ensure close tolerances and optimal sealing.
Swashplate: The swashplate is a crucial component that converts the rotary motion of the drive shaft into axial movement of the pistons. It is made from hardened steel and can be adjusted to vary the displacement of the pump, allowing for variable flow output.
Valve Plate: The valve plate regulates the flow of hydraulic fluid into and out of the pistons. It contains various control valves and passages that direct the pressurized fluid. The valve plate is precisely machined and has excellent sealing properties to ensure efficient pump operation.
Port Plate: The port plate provides the necessary connections for hydraulic lines, allowing fluid to enter and exit the pump. It is made from durable materials and is designed for easy installation and maintenance.
Shaft Seal: The shaft seal prevents hydraulic fluid from leaking along the drive shaft. It is typically a high-quality radial lip seal or mechanical seal, ensuring reliable sealing and preventing contamination of the system.
Control Options: The A20VO series pumps offer different control options to meet specific application requirements. These include manual control, hydraulic control, and electro-proportional control, allowing for precise flow regulation and system optimization.
Mounting Options: The pumps are available in various mounting configurations, such as flange or foot mounting.
This versatility allows for easy integration into different hydraulic systems.
Maintenance and Service: The A20VO series is designed for easy maintenance and serviceability. Critical parts can be accessed and replaced quickly, reducing downtime and maintenance costs.
Performance and Efficiency: Rexroth A20VO pumps are known for their high performance and efficiency. They offer precise control of hydraulic flow, allowing for optimal system operation. The pumps are designed to minimize energy losses and maximize overall efficiency.
