20VQ High‑Speed High‑Pressure Vane Pump
Product Overview
20VQ is a single‑stage fixed‑displacement high‑speed high‑pressure Hydraulic Vane pump, a compact lightweight hydraulic pump designed for stable oil supply in small‑to‑medium industrial hydraulic system and various hydraulic‑driven Machine.
This compact Hydraulic Vane pump adopts balanced vane structure with floating side‑plate automatic clearance compensation. It features low flow pulsation and low‑noise operation, and supports continuous high‑speed and high‑pressure working conditions. The modular cartridge‑kit design enables convenient on‑site maintenance without removing the entire pump housing from the Machine. It is an ideal power‑supply component for small hydraulic stations, packaging machinery, auxiliary injection‑molding equipment and light‑to‑medium‑load industrial Machine.

Working Principle
20VQ 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. Compact size with balanced vane design, reduces radial bearing load and extends service life under cyclic operation of the Machine.
2. Floating side‑plate automatic clearance compensation, keeps high volumetric efficiency under high‑pressure and high‑speed operation 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
20VQ single‑stage Hydraulic Vane pump is a key power‑supply hydraulic pump for light‑to‑medium‑load industrial hydraulic system. It is widely applied to small hydraulic stations, packaging machinery, injection‑molding auxiliary equipment, small‑size machine tools and other hydraulic‑driven industrial Machine. Suitable for hydraulic‑system integrators, equipment manufacturers, maintenance workshops and global spare‑parts distributors.
