Product Overview
The Linde HPR series (including HPR55, HPR75, HPR105, HPR135, HPR165, and HPR210) is a high-pressure variable displacement axial piston pump platform known for its high torque density and extreme load capability. Operating under continuous high-pressure cycles, internal components—such as the cylinder block, piston shoes, valve plate, and swashplate—endure severe thermal and mechanical friction, leading to performance issues like hydraulic drift, pressure drops, system overheating, or reduced operation speed.
HYLINK manufactures high-precision complete rotary groups and individual replacement components for the entire Linde HPR pump range. Crafted from high-strength forged alloy steel and wear-resistant bronze alloys, every part undergoes precision CNC machining and CMM micron-level verification. This allows repair technicians to replace specific worn components instead of buying a whole new pump, significantly lowering repair costs and minimizing machine downtime.

Quality Assurance & Manufacturing
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.
