The A4VSO250DRG/30R-PPB25U99 is a high-performance pump manufactured by Kawasaki, a renowned company specializing in hydraulic systems and components.
This particular model is part of their A4VSO series, known for its reliability, efficiency, and versatility.
The pump's displacement is variable, meaning it can adjust the flow rate according to the system requirements. The displacement range for this model is 250 cc/rev, allowing it to handle a wide range of hydraulic applications with varying flow demands.
The pump operates based on axial piston principles. It features a cylinder block with several pistons arranged in an axial configuration. These pistons are driven by a swashplate mechanism, allowing them to reciprocate within their respective cylinders. As the pistons move back and forth, they generate hydraulic pressure and deliver fluid to the system.
The A4VSO250DRG/30R-PPB25U99 has a maximum operating pressure of 350 bar (5,075 psi). This robust pressure capability makes it suitable for demanding applications that require high-pressure hydraulic power. It can effectively handle tasks such as heavy-duty lifting, pressing, and powering hydraulic motors.
To ensure reliable and efficient operation, the pump incorporates various design features. It employs a pressure compensator system that automatically adjusts the swashplate angle to maintain a constant outlet pressure. This feature helps optimize energy consumption and system performance by matching the pump output to the load requirements.
Additionally, the pump is equipped with a built-in pressure relief valve that protects the system from excessive pressure.
This safety feature prevents damage to the pump and the connected hydraulic components by diverting excess fluid back to the reservoir when the pressure exceeds the specified limit.
The A4VSO250DRG/30R-PPB25U99 pump has a nominal speed range of 1500 to 2700 RPM (revolutions per minute). This flexibility allows it to accommodate different operating conditions and adapt to various industrial environments.
In terms of construction, the pump features a robust housing made of high-quality materials to withstand demanding operating conditions. It is designed to provide long service life and reliable performance, minimizing downtime and maintenance costs.
The pump's model code, A4VSO250DRG/30R-PPB25U99, indicates specific details about its configuration and options. For instance, the "30R" refers to the pump's control type, which in this case is the DRG electronic control with proportional pressure compensator. The "PPB25U99" part indicates the shaft end, mounting flange, and porting specifications.
