45VQ High‑Speed High‑Pressure Vane Pump
Product Overview
45VQ is a single‑stage fixed‑displacement high‑speed high‑pressure Hydraulic Vane pump, a robust heavy‑duty hydraulic pump designed for stable oil supply in industrial hydraulic system and various heavy‑load hydraulic‑driven Machine.
This high‑performance Hydraulic Vane pump adopts balanced vane structure with floating side‑plate automatic clearance compensation. It supports continuous high‑speed and high‑pressure operation, delivering low flow pulsation and low‑noise performance. The modular cartridge‑kit design enables convenient on‑site maintenance without removing the whole pump housing from the Machine. It is an ideal power‑source component for die‑casting machinery, large hydraulic presses, injection‑molding equipment and other heavy‑duty industrial Machine.

Working Principle
45VQ Hydraulic Vane pump consists of rotor, vanes, cam ring, floating side plates and cast‑iron pump housing. Driven by the input shaft, the rotor rotates and centrifugal force pushes vanes tightly against the inner surface of cam ring. Periodic volume variation between vanes realizes oil suction and pressure delivery to supply the whole hydraulic system. Floating side plates conduct automatic axial clearance compensation under hydraulic pressure, maintaining high volumetric efficiency under long‑term high‑speed and high‑pressure working conditions of the Machine.
Worn vanes, cam ring or side plates will cause internal leakage, pressure drop, abnormal noise and insufficient flow output of the hydraulic pump. Installing matching VQ Series Cartridge Kit can quickly restore full performance of your hydraulic system.
Core Advantages
1. Balanced vane design reduces radial bearing load, extends service life under heavy‑duty cyclic operation of the Machine.
2. Floating side‑plate automatic clearance compensation, keeps high volumetric efficiency at high‑pressure and high‑speed working conditions of hydraulic system.
3. Modular replaceable cartridge‑kit structure, maintenance can be completed without detaching the whole pump from Machine, greatly reducing downtime of hydraulic system.
4. Low flow pulsation and low‑noise operation, improves running stability of hydraulic‑driven equipment.
5. Standard flange mounting dimension, good interchangeability for original replacement and retrofitting existing hydraulic system.
Application Range
45VQ single‑stage Hydraulic Vane pump is a key power‑supply hydraulic pump for heavy‑duty industrial hydraulic system. It is widely applied to die‑casting machines, large hydraulic presses, injection‑molding equipment, metallurgical machinery, heavy‑duty machine tools and other hydraulic‑driven industrial Machine. Suitable for hydraulic‑system integrators, equipment manufacturers, maintenance workshops and global spare‑parts distributors.
