Product Overview
The Sauer Danfoss 90 Series (including PV90R variable pumps and 90M fixed/variable motors) is a widely recognized standard in high-pressure closed-circuit hydrostatic transmissions. Operating under demanding high-torque and high-pressure duty cycles (up to 420 bar working pressure), internal components—such as the cylinder block, piston shoes, valve plate, swashplate, and charge pump—undergo continuous friction and thermal degradation over prolonged use, leading to reduced propulsion power, oil temperature elevation, pressure instability, or excessive noise.
HYLINK manufactures high-precision complete rotary groups and individual replacement components across all Sauer Danfoss 90 Series displacements, from 90R030 to 90R250. Engineered from high-strength forged alloy steel and high-leaded wear-resistant bronze alloys, each part is CNC-machined to micron-level tolerance and verified via CMM inspection. This allows maintenance personnel to perform targeted replacement of worn components rather than substituting the entire pump/motor assembly, drastically cutting overhaul expenses 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.
