The Sauer Danfoss 90 series 90R 90L hydraulic pump (English keyword: Sauer Danfoss 90 series 90R 90L hydraulic pump) is a heavy-duty axial piston platform engineered for high flow, high pressure and continuous industrial duty. Models covered include 90R042, 90R055, 90R075, 90R100, 90R130, 90R180, 90R250 axial piston pumps and the corresponding 90L042, 90L055, 90L075, 90L100, 90L130, 90L180, 90L250 piston pump. These pumps are designed for robust service in tractors, excavators, wheel loaders, mining trucks and stationary drive units where system reliability and low life-cycle cost are critical.
Design strengths & operating envelope
90R/90L pumps combine high volumetric efficiency with reinforced housings and high-integrity swashplate assemblies. They tolerate frequent pressure transients and are available with options for explosion-protected installations and corrosion-resistant finishes. Typical system applications run at elevated pressures and long duty cycles; these pumps are built to minimize internal leakage and thermal build-up, extending service intervals and reducing downtime. All units carry a one-year warranty.

FAQ
Q1: What differentiates 90R vs 90L variants?
A1: 90R and 90L denote flange/shaft and mounting configurations and internal porting suited to different system layouts; performance envelopes are comparable.
Q2: Are these pumps suitable for explosive or offshore environments?
A2: Yes — explosion-protected options and special coatings are available; specify environmental options at order.
Q3: How to maximize service life?
A3: Maintain ISO-grade fluid cleanliness, proper cooling, and monitor transient pressure spikes with accumulators or dampeners.
Q4: Is OEM interchange supported?
A4: BAOLILAI offers OEM-compatible replacements and customization; request exact PDF drawings via www.baolilai-pump.com/contact_us/.
