Flow Range: The PVH series covers a wide flow range, typically from 7 to 140 liters per minute (LPM).
This variety allows for the selection of a pump that matches the specific application's flow requirements.
Pressure Ratings: PVH pumps are capable of delivering high pressure, with some models capable of reaching up to 350 bar (5,000 psi). This makes them suitable for demanding applications where high pressures are essential.
Speed Range: These pumps are designed to work at various speeds, usually between 600 and 1800 RPM, enabling adaptability to different operational needs.
Fluid Compatibility: PVH piston pumps are compatible with a range of hydraulic fluids, including mineral oils, synthetic fluids, and biodegradable fluids, depending on the model.
Construction: The pump housing is typically made from high-strength materials like cast iron or aluminum to ensure durability. The components are precision-engineered to reduce wear and enhance pump life.
Control Options: PVH pumps are available with multiple control options, including pressure compensators, load-sensing controls, and manual displacement control, allowing for fine-tuning to the specific application.
Cylinder Block: The heart of the piston pump, it houses the piston assemblies and is responsible for creating the high-pressure hydraulic flow.
The cylinder block is precision-machined to ensure efficiency and reliability.
Pistons: The PVH series uses axial pistons that reciprocate within the cylinder block. These pistons are precisely manufactured to maintain a tight seal and reduce internal leakage.
Valve Plate: The valve plate controls the flow of hydraulic fluid into and out of the cylinder block, regulating the pump's displacement and pressure output.
Shaft: The drive shaft connects to the pump's prime mover, typically an electric motor or an engine, and transfers the rotational motion to the cylinder block.
Housing: The pump housing encases all the internal components and provides support and protection. It is designed to withstand high pressures and harsh operating conditions.
Control Mechanisms: Depending on the model, PVH pumps can incorporate various control mechanisms to adjust flow and pressure as needed. These may include swashplates, servo pistons, and load-sensing valves.
