Working Principle

The PVP pump operates on the axial piston principle. A rotating cylinder block contains pistons that reciprocate against a swashplate. The angle of the swashplate determines the piston stroke and thus the pump's displacement. A sophisticated control piston automatically adjusts the swashplate angle based on the selected control method (e.g., pressure, load signal, or electrical input), varying the output flow to precisely meet system requirements without excess energy loss.

Industry Applications

PVP pumps are engineered for a wide range of mobile and industrial applications, including:

· Construction Machinery: Excavators, wheel loaders, backhoes, telehandlers
· Agricultural Equipment: Tractors, combines, forage harvesters
· Material Handling: Forklifts, reach stackers, empty container handlers
· Municipal Vehicles: Street sweepers, refuse trucks
· Industrial Machinery: Presses, winches, test stands

How to Select the Right PVP Pump

Selecting the correct pump requires analyzing your system needs:

1. Flow Requirements: Determine maximum and minimum flow needs (L/min) based on actuator speeds.
2. Pressure Rating: Identify the system's maximum operating and peak pressures.
3. Control Strategy: Choose the right control type (e.g., pressure compensation for constant pressure, load sensing for flow-on-demand) based on your machine's function.
4. Drive Specifications: Match the pump's displacement and speed range to your prime mover (diesel engine or electric motor).
5. Mounting and Interfaces: Confirm SAE mounting flange type and port sizes.

Frequently Asked Questions (FAQ)

· Q: What is the difference between pressure compensation and load sensing control?
  · A: A pressure compensator adjusts flow to maintain a set pressure. Load Sensing (LS) adjusts both flow and pressure to meet the demand of the actuator with the highest load, only providing the necessary pressure plus a small margin, making it highly efficient for systems with multiple functions.
· Q: Can I get the PVP pump with an integrated charge pump?
  · A: Yes, many PVP models are available with a built-in gear-type charge pump for closed-loop circuit replenishment or to supply pilot pressure.
· Q: Where can I find a detailed technical document for the PVP series?
  · A: Full datasheets, dimensional drawings, Contact us to request these documents directly.
· Q: Do you provide repair services for PVP pumps?
