Pump Housing: The pump housing is made of high-strength cast iron or aluminum alloy, providing excellent durability and resistance to corrosion.
It houses all the internal components of the pump, ensuring proper alignment and support.
Rotor Assembly: The rotor assembly consists of a slotted rotor and vanes. The rotor is driven by a driveshaft connected to an external power source, such as an electric motor. The vanes slide in and out of the rotor slots, creating chambers of varying volumes to generate suction and discharge pressures.
Inlet Port: The pump features an inlet port through which the fluid enters the pump. The inlet port is designed to minimize flow losses and ensure smooth fluid intake.
Outlet Port: The outlet port is where the pressurized fluid is discharged from the pump. It is designed to handle high-pressure flows efficiently and reliably.
Vanes: The vanes are crucial components of the PVB pump. They slide in and out of the rotor slots, maintaining contact with the pump housing inner surface and creating pumping chambers. The vanes are typically made of a self-lubricating composite material, such as carbon or graphite-impregnated material, to reduce friction and wear.
Bearings: The PVB series incorporates high-quality bearings to support the rotor assembly and minimize shaft deflection. These bearings are typically made of hardened steel or bronze and are designed to withstand high loads and provide smooth operation.
Shaft Seal: To prevent fluid leakage, the PVB pump utilizes a shaft seal, such as a lip seal or mechanical seal, between the driveshaft and the pump housing. The shaft seal ensures that the pressurized fluid remains within the pump, maintaining system efficiency.
Control Options: Eaton Vickers PVB series pumps offer various control options to meet different application requirements.
These options include pressure compensators, pressure and flow control valves, and load sense control. These controls allow for precise adjustment of pump output and optimize system performance.
Mounting Options: The PVB series pumps are designed for easy integration into different systems. They can be mounted using standard SAE or ISO flanges, providing flexibility in installation and replacement.
Performance and Efficiency: The PVB series is known for its high volumetric efficiency, which results in excellent pump performance. These pumps can operate at a wide range of speeds and pressures, delivering reliable and consistent output. Additionally, the vane design minimizes internal leakage, improving overall efficiency.
Serviceability: Eaton Vickers PVB pumps are designed for easy maintenance and service. The modular design allows for quick replacement of worn-out parts, minimizing downtime and reducing maintenance costs. Service kits are available, containing all the necessary components for servicing the pump.
