4535VQ High‑Speed High‑Pressure Vane Pump
Product Overview
4535VQ is a double‑pump fixed‑displacement high‑speed high‑pressure Hydraulic Vane pump, a heavy‑duty hydraulic pump designed to deliver dual independent flow outputs for complex industrial hydraulic system and heavy‑load hydraulic‑driven Machine .
This robust Hydraulic Vane pump adopts balanced intra‑vane structure with floating side‑plate clearance compensation. It supports high rotating speed and continuous high‑pressure operation, featuring low flow pulsation and low noise performance. The modular cartridge‑kit design facilitates quick maintenance on site, making it an ideal power source for die‑casting equipment, heavy‑duty hydraulic presses, engineering machinery and other high‑demand industrial Machine.

Working Principle
4535VQ Hydraulic Vane pump integrates two sets of independent vane pumping assemblies inside one pump housing. Driven by the driving shaft, the rotor pushes vanes outward against the cam‑ring inner wall by centrifugal force. Periodic volume variation formed between vanes realizes oil suction and pressure delivery. Two pump units output independent flow to satisfy multi‑circuit demands of the hydraulic system. Floating side plates perform automatic axial clearance compensation under hydraulic pressure, maintaining high volumetric efficiency under long‑term high‑speed and high‑pressure operation of the Machine .
Excessive wear of vanes, cam ring or side plates will cause internal leakage, pressure drop, abnormal noise and insufficient flow of the hydraulic pump. Replacing with matched VQ series cartridge kit can rapidly restore full performance of your hydraulic system.
Core Advantages
1. Double‑pump integrated structure, two separate flow outputs, perfectly meets multi‑loop power‑supply requirements of complex hydraulic system.
2. High‑speed and high‑pressure resistance, balanced vane design reduces radial load, extends service life under heavy‑duty working cycles of the Machine.
3. Modular replaceable cartridge kit, no need to remove whole pump body from Machine during overhaul, greatly shortens downtime of hydraulic system .
4. Low flow pulsation and low noise, improves running stability of complete hydraulic equipment.
5. Standard installation dimension, good interchangeability for original replacement and retrofitting existing hydraulic system.
Application Range
4535VQ double‑unit Hydraulic Vane pump is a core power‑supply hydraulic pump for heavy‑duty hydraulic system. Widely applied for die‑casting machines, large hydraulic presses, injection molding equipment, metallurgical machinery, construction machinery and other heavy‑duty hydraulic‑driven industrial Machine. Popular among equipment manufacturers, hydraulic station integrators, repair workshops and global spare‑parts distributors.
