Housing: The pump's housing is made of high-strength cast iron or ductile iron, providing durability and resistance to wear and corrosion.
It is designed to withstand high pressure and ensure the integrity of the internal components.
Rotor: The PVH Series pumps feature a balanced, double-ended rotor with vanes that slide in and out of the rotor slots. The rotor is precision-machined to ensure smooth operation and minimize internal leakage.
Vanes: The vanes are typically made of a composite material that offers excellent wear resistance and low friction. They are self-adjusting and provide consistent performance over time. The vanes maintain contact with the housing and create chambers that trap and move the fluid during operation.
Inlet and Outlet Ports: The pump is equipped with inlet and outlet ports for fluid intake and discharge. These ports are designed to minimize pressure losses and ensure efficient fluid flow throughout the system.
Shaft Seal: The PVH Series pumps feature a shaft seal that prevents fluid leakage along the shaft. This seal is typically a combination of lip seals and O-rings that provide reliable sealing and prevent contamination of the hydraulic fluid.
Pressure Compensator: The pumps are often equipped with a pressure compensator that adjusts the displacement of the pump in response to system pressure. This feature allows the pump to maintain a constant pressure and flow rate, enhancing system performance and efficiency.
Control Options: The PVH Series pumps offer various control options to meet specific application requirements. These options include manual, hydraulic, or electro-hydraulic controls for adjusting the displacement, pressure, or flow rate of the pump.
Mounting Flange: The pumps are designed with a mounting flange that allows for easy installation and integration into hydraulic systems.
The flange provides a secure connection between the pump and the mounting surface.
Bearing System: The PVH Series pumps incorporate a robust bearing system that supports the rotor and ensures smooth and reliable operation. The bearings are designed to withstand high loads and provide long service life.
Serviceability: Eaton Vickers pumps are designed with serviceability in mind. The PVH Series pumps feature a cartridge kit design, which allows for easy replacement of worn or damaged components without disassembling the entire pump. This reduces downtime and maintenance costs.
