One of the notable features of the Eaton Vickers PVE19, PVE21, and PVE21R pumps is their axial piston design.
These pumps utilize a swashplate mechanism to convert mechanical power into hydraulic energy. This design ensures smooth operation, reduced noise levels, and improved efficiency compared to other types of hydraulic pumps.
The displacement of these pumps varies depending on the model. The PVE19 pump has a displacement range of 19 cm³/rev, while the PVE21 and PVE21R pumps offer a displacement range of 21 cm³/rev. This displacement determines the volume of fluid delivered by the pump per revolution, allowing for precise control of hydraulic systems.
The Eaton Vickers PVE19, PVE21, and PVE21R pumps are capable of operating at high pressures. They can handle pressures up to 350 bar (5,075 psi), ensuring reliable performance even in demanding applications. These pumps also feature a wide speed range, allowing for flexibility in system design and operation.
To ensure durability and longevity, these pumps are constructed with high-quality materials.
The pump body is made of robust cast iron, providing excellent resistance to wear and corrosion. Additionally, the swashplate mechanism and pistons are made from high-strength steel, enabling them to withstand high pressures and continuous use.
These hydraulic pumps are designed for easy installation and maintenance. They are equipped with SAE mounting flanges, allowing for straightforward integration into hydraulic systems. The pumps also feature a cartridge-style design, which facilitates quick and easy replacement of internal components, reducing downtime and maintenance costs.
The PVE21R model includes a built-in pressure relief valve. This feature ensures system safety by limiting the maximum pressure and protecting against overloading. It eliminates the need for an external relief valve, simplifying system design and reducing installation complexity.
In terms of control options, these pumps offer various choices to meet specific application requirements. They can be operated with either manual or electro-proportional control, allowing for precise flow and pressure regulation. This flexibility makes the Eaton Vickers PVE19, PVE21, and PVE21R pumps suitable for a wide range of applications, from simple hydraulic systems to advanced control systems.
