Basic Parameters & Introduction
This high-precision heavy-duty closed hydraulic main pump assembly is derived from the Sauer Danfoss industrial grade star 90R series variable displacement axial piston pump. This series covers the entire generation of core displacements such as 042, 055, 075, 100, 130, 180, 250, etc. The specific long code configuration of this product is 90R100HF1NN80R3C7D03GBA424224 (a classic electronic control model with a displacement of 100cc). As the fluid power heart of the closed transmission system, it is widely matched with the walking and operation circuits of road machinery, large tonnage rollers, rotary drilling rigs, concrete mixers, and heavy engineering machinery. The product is based on first principles optimization of electro-hydraulic control response, ensuring absolute certainty of high-pressure and high flow output. Taking 100 displacement as an example, the physical dimensions of the packaging are approximately 490mm × 290mm × 310mm, and the overall net weight is about 49kg. The original factory standard hole positions are precisely aligned.

Maintenance Tips
Daily inspection (every 10 hours): Before starting work every day, it is mandatory to inspect the pump body shaft seal, the differential pressure indicator of the oil replenishment pump, and the interface of the electric proportional valve to prevent negative pressure suction and trace leakage hazards.

First break in oil change (50 hours of operation): After the new pump or major overhaul component has been running online for 50 hours, it must be forcibly replaced with a high-precision oil replenishment filter specifically designed for the closed circuit to thoroughly remove the initial hard particles.

Regular mandatory replacement (every 500/2000 hours): Replace the high-precision closed filter element of the entire vehicle every 500 hours; Thoroughly clean the hydraulic oil tank every 2000 hours (or up to 1 year) and replace it with high-quality anti-wear/high viscosity hydraulic oil from the original factory. When the working conditions are harsh, the cycle needs to be forcibly halved.

Installation Tips
Extreme cleaning and torque tightening: Before installation, the environment needs to be treated with dust removal. Tightening bolts and high-pressure pipeline flanges must be done using torque wrenches, strictly following the factory's specified torque for symmetrical and phased cross tightening, to prevent slight deformation of the aluminum control valve block or main housing due to stress concentration.

Forced oil filling and replenishment (core pit avoidance): Before starting the engine, clean hydraulic oil must be filled from the housing drain port at the top of the main pump, while ensuring that the suction pipeline of the closed circuit charge pump is unobstructed. It is strictly prohibited to start dry grinding, otherwise the internal rotating components will undergo irreversible physical erosion within 3 seconds of ignition.

Low pressure exhaust and pressure monitoring: After the first ignition, force the engine to idle at low pressure for 10-15 minutes for full system exhaust and thermodynamic adaptation, and closely monitor the charge pressure. After the oil temperature and replenishment pressure are stable and the bubbles are cleared, the workload can be gradually applied.

Key Features and Buyer Benefits

  • Part-number-led identification: 90R100HF1NN80R3C7D03GBA424224 is used as the starting point for fitment review.
  • Machine-specific matching: the Sauer Danfoss 90R100 application is checked against serial number, nameplate and physical interface before dispatch.
  • Condition transparency: request new OEM-replacement, aftermarket-replacement, remanufactured or tested used status as separate quotation options.
  • Inspection evidence: ask for actual product, nameplate, shaft, ports and mounting photos before shipment.
  • Export packing: request moisture protection, internal padding, crate dimensions and final gross weight for international transport.
  • Purchasing support: XINYA can combine part-number checking, availability review, warranty terms and freight options in one quotation.

Compatibility and Fitment Confirmation

Fitment for the Sauer Danfoss 90R100 application should be confirmed by more than the product title. The same machine family can use different hydraulic pump configurations across serial ranges, production years or attachment packages. Send the following information for a reliable check:

  • Machine brand, full model and serial number
  • Engine model and operating hours, where available
  • Old pump part number, including 90R100HF1NN80R3C7D03GBA424224 if shown on the nameplate
  • Nameplate, connector, shaft, flange and mounting photos
  • Required quantity, preferred condition and delivery country
  • Any known symptoms such as low pressure, overheating, noise or leakage

Installation and Maintenance Guidance

  • Flush the hydraulic tank and connected piping before installation and remove metallic debris, sealant fragments and other contamination.
  • Keep hoses, ports, fittings and the pump housing sealed and clean during handling.
  • Fill the pump housing with clean anti-wear hydraulic oil before startup; dry running can damage internal components.
  • Check alignment, coupling, flange bolts, oil level, filters and pressure settings against the machine service manual.
  • Bleed trapped air, run at idle without load, inspect for leakage and abnormal noise, then increase load gradually.
  • Record the installed pump part number and initial operating readings for future maintenance tracking.

These are general replacement-pump precautions. Final installation, oil grade, filter interval and pressure settings must follow the equipment manufacturer manual and the documentation supplied with the selected pump.

Condition, Warranty and Shipping

The current product page should be used as the commercial reference for MOQ, price terms, packaging, availability and delivery. Because these fields can vary by condition and stock location, request a written quotation that identifies the exact pump, condition, inspection scope, warranty period, processing time and transit time. Ask whether the quoted delivery period is working days before dispatch or total door-to-door lead time.

For export orders, confirm wooden-case or equivalent protective packaging, moisture protection, packing-list details, gross weight, case dimensions and shipping marks. Sea freight, air freight and express delivery can be compared according to urgency, destination and shipment weight.

Frequently Asked Questions

Is this pump suitable for Sauer Danfoss 90R100?

The listing identifies Sauer Danfoss 90R100 as the target application, but final fitment should be checked by part number, machine serial number and physical interface before purchase.

Can I choose a new or used pump?

Ask XINYA to quote each available condition separately. The quotation should state whether the unit is OEM-replacement, aftermarket-replacement, remanufactured or tested used, together with the applicable warranty.

What technical data should be confirmed?

Confirm displacement, rated pressure, flow, rotation, shaft, mounting pattern, port dimensions and final weight from the nameplate or technical drawing.

What photos are needed for matching?

Send the old pump nameplate, front and rear views, shaft, flange, ports, connectors and mounting points, together with the machine serial plate.

How do I request a quotation?

Send the part number, machine model and serial number, required quantity, preferred condition, destination country and delivery target. XINYA can then return a fitment and commercial quotation.
