3525VQ High‑Speed High‑Pressure Vane Pump
Product Overview
3525VQ is a double fixed‑displacement high‑speed high‑pressure Hydraulic Vane pump, a compact heavy‑duty hydraulic pump built to supply two independent flow outputs for complex industrial hydraulic system and various hydraulic‑driven Machine.
This robust Hydraulic Vane pump adopts balanced intra‑vane design together with floating side‑plate automatic clearance compensation. It supports stable high‑speed continuous operation with low flow pulsation and low noise. Thanks to the modular replaceable cartridge kit structure, on‑site maintenance becomes simple and efficient. It serves as reliable power source for injection‑molding machinery, hydraulic presses, machine tools and medium‑heavy‑load industrial Machine.

Working Principle
3525VQ Hydraulic Vane pump contains two independent vane pumping assemblies inside one cast‑iron housing. Driven by input shaft, rotors spin and centrifugal force pushes vanes tightly against cam‑ring inner surface. Periodic volume change between vanes finishes oil suction and oil delivery. Two pumping sections deliver separate flow to satisfy multi‑circuit requirements of your hydraulic system. Floating side plates perform automatic axial clearance compensation under hydraulic pressure, preserving high volumetric efficiency under long‑term high‑speed, high‑pressure operation of the Machine.
Severe wear on vanes, cam ring or side plates will trigger internal leakage, pressure loss, abnormal noise and insufficient output flow of the hydraulic pump. Installing matched VQ series cartridge kit can quickly restore full performance of the whole hydraulic system.
Core Advantages
1. Compact double‑pump integrated construction, two separate flow outputs, perfectly meets multi‑loop power‑supply demand of complex hydraulic system.
2. Balanced intra‑vane structure lowers radial load on bearings, improves service life under cyclic heavy‑load operation of Machine.
3. Modular cartridge‑kit design. Overhaul can be finished without removing the whole pump body from Machine, cutting downtime of hydraulic system.
4. Low flow pulsation and low‑noise performance, improving overall running stability of hydraulic‑driven equipment.
5. Standard installation dimension, great interchangeability for original replacement and retrofitting existing hydraulic system.
Application Range
3525VQ dual‑unit Hydraulic Vane pump is an essential power‑supply hydraulic pump for heavy‑duty hydraulic system. It is widely used in injection molding machines, hydraulic presses, die‑casting equipment, metal‑cutting machine tools, light engineering machinery and other hydraulic‑driven industrial Machine. Popular for hydraulic system integrators, equipment manufacturers, maintenance workshops and global spare‑parts distributors.
