DP4 Hydraulic Vane Pump

Product Overview

DP4 Hydraulic Vane Pump is a fixed‑displacement single Hydraulic Vane pump. This heavy‑duty hydraulic pump delivers stable pressure and flow output for medium‑high‑pressure industrial hydraulic system and medium‑heavy‑load hydraulic‑driven Machine.

This Hydraulic Vane pump adopts mature balanced vane structure, which brings low pressure pulsation and quiet operation. It features cartridge‑in‑housing construction, with interchangeable DP4 cartridge kit for convenient on‑site maintenance without full pump disassembly. It is widely applied to medium‑size injection molding machines, hydraulic presses and general industrial equipment, serving as reliable power source for the whole hydraulic system.

Working Principle

As a single‑unit Hydraulic Vane pump, this hydraulic pump works by periodic volume change. Driven by input shaft, rotor and vanes rotate inside the cam ring. Centrifugal force pushes vanes tightly against inner surface of the cam ring. Volume expansion draws in hydraulic oil, while volume compression outputs high‑pressure oil to supply power for the complete hydraulic system. The balanced‑vane structure offsets radial hydraulic force, lowering vibration and wear during long‑time running of the Machine.

When vanes, cam ring or side plates suffer wear, the hydraulic pump will generate internal leakage, pressure drop, insufficient flow and abnormal noise. Installing matched DP4 cartridge kit can rapidly restore full working performance of your hydraulic system.

Core Advantages

1. Proven balanced vane structure, reduces pressure pulsation and vibration, delivers steady pressure‑flow output for medium‑heavy‑load industrial Machine.

2. Modular cartridge‑in‑housing design, supports quick field overhaul without removing the whole hydraulic pump from the Machine, greatly reduces downtime of hydraulic system.

3. Standard mounting and port dimensions, good interchangeability for original replacement and hydraulic system retrofitting.

4. High volumetric efficiency under continuous medium‑high‑pressure operation, stable performance for long‑time continuous production.

5. Robust single‑pump housing, suitable for heavy‑load working conditions in industrial Machine.

Application Range

DP4 Hydraulic Vane pump is a key power‑supply hydraulic pump for industrial hydraulic system. Widely used in medium‑sized injection‑molding machinery, hydraulic presses, machine tools, packaging equipment and other hydraulic‑driven industrial Machine. Popular among hydraulic repair workshops, equipment integrators and global spare‑parts distributors.
