Product Overview
The Oilgear PMP12, PVP (PVP90/110), and PVWH (PVWH110) axial piston pump series are built for extreme continuous duty in high-pressure industrial environments. Operating under high fluid pressures and heavy shock loads, critical internal components—such as the cylinder block, piston shoes, wear plate/valve plate, and yoke swashplate assembly—face intense surface friction and fluid shear over prolonged operation. This wear can result in internal bypass, system pressure drops, elevated hydraulic oil temperatures, or excessive vibration and noise.
HYLINK manufactures high-precision complete rotary groups and individual replacement spare parts across the Oilgear PMP12, PVP90, PVP110, and PVWH110 model lines. Engineered from high-strength forged alloy steel and specialized wear-resistant bronze alloys, each part undergoes precision CNC machining and CMM dimensional inspection. This allows technical teams to execute targeted internal component rebuilds without incurring the high cost and long lead time of replacing the entire pump assembly, significantly reducing overhaul expenses and minimizing plant downtime.

Every HYLINK pump and replacement part undergoes strict quality control before shipment:
l Dimensional accuracy — checked with high-precision CMM (Coordinate Measuring Machines) to guarantee an exact fit with original pump housings.
l Material metallurgy — manufactured from premium forged steel and high-wear-resistant alloys to prevent premature fatigue.
l 100% performance test — every complete pump assembly is tested on our dynamic hydraulic test rig for pressure, flow rate and efficiency under full working load.
Packing, Shipping & Warranty
l Packaging — anti-rust protective film + heavy-duty foam cushioning + standard export fumigation-free wooden case (reinforced carton for small spare parts).
l Shipping — express courier (DHL / FedEx) for urgent repair orders; sea or air cargo for bulk orders.
l Warranty — 6 months quality assurance against manufacturing and material defects from the delivery date. In the event of a confirmed quality defect, HYLINK provides hassle-free replacement.
