Vickers PVQ Series Variable Axial Piston Pump
Guangdong Haozheng Hydraulic Equipment Co., Ltd. specializes in manufacturing high-efficiency, quiet-running Vickers PVQ series variable displacement axial piston pumps. Engineered specifically to meet the stringent low-noise requirements of modern industrial factory floors, the PVQ series features an optimized timing plate and acoustic dampening stroke configuration that significantly reduces fluid-borne and mechanical noise sound pressure levels.
As your professional global B2B hydraulic partner, Haozheng delivers complete PVQ pump assemblies and high-precision replacement components with 100% dimensional and operational interchangeability with original Eaton Vickers units. To ensure immediate drop-in reliability on your production line, every single pump undergoes comprehensive volumetric efficiency and pressure limits calibration on our advanced hydraulic test benches before international dispatch.

Plastic Injection Molding Machines (注塑机): Maintaining quiet and high-repetition clamping, holding, and injection fluid circuits on busy factory floors.
-
Die-Casting Machinery (压铸机械): Delivering highly responsive and precise pressure adjustments for commercial non-ferrous metal molding systems.
-
Industrial Press Stations (油压机/液压机系统): Powering automated metal forming, stamping, stamping molds, and scrap metal bailing systems.
-
Port & Marine Hydraulic Controls (港口船舶机械): Serving as auxiliary hydraulic power units for marine deck winches, lift gates, and steering gears.
-
Automated Machine Tool Power Packs (机床动力单元): Supplying uniform oil flow to heavy-duty industrial CNC tooling systems, broaching machines, and factory production lines.

Frequently Asked Questions (FAQ)
Q1: Can I use Haozheng PVQ internal parts to rebuild an original original Vickers PVQ pump? A: Yes, absolutely. Our full line of PVQ internal replacement parts—including pistons, cylinder blocks, valve plates, swashplate cradles, and shaft extensions—are machined to precise micron tolerances that completely align with original Vickers specifications.
Q2: Why is the PVQ series noticeably quieter than the standard PVB series? A: The PVQ series incorporates advanced sound-dampening modifications, including an altered internal timing mechanism and a stiffer casting envelope. These engineering updates reduce pressure pulsations and absorb operational vibrations, dropping decibel levels down to comfortable indoor-factory standards.
Q3: What causes pressure instabilities or erratic responses in a PVQ pump? A: Erratic pressure response is typically caused by contamination or varnish accumulation inside the pilot control valve spool (such as the DR or LRDS block), which restricts free movement. We recommend cleaning the compensator spool or inspecting your system’s main filtration circuit. If the control block is damaged, Haozheng supplies standalone, 100% interchangeable PVQ compensator valves for quick restoration.
