M32-A-D1-Q1-M2-0-0-VB-F Hydro Leduc Bent Axis Motor 400 bar

Product Overview

M32-A-D1-Q1-M2-0-0-VB-F is a fixed-displacement bent-axis piston hydraulic motor in the HYDRO LEDUC M series (ISO / CETOP version), frame size 32, with a geometric displacement of 32.1 cc/rev. Machined to the original M32 interface envelope, ISO 3019-2 flange, DIN 6885 keyed shaft, and SAE flange ports, it serves as a drop-in interchangeable replacement for the original M32 motor without modifying brackets or piping.

The M-series motor uses a 40-degree bent-axis, 7-piston design that converts flow into speed and pressure into torque. It combines high power density with a compact envelope, delivers global efficiency above 90% in most applications, and runs in both directions, making it suitable for continuous heavy-duty service in open or closed circuits. Our positioning is high-pressure hydraulic manufacturing with emphasis on original-position interchangeability and 100% simulated operating-condition testing before shipment, reducing field failures and unplanned downtime.

Key Technical Advantages

• Original-position interchangeability: Built to the original M32 ISO 3019-2 flange, DIN 6885 keyed shaft, and SAE flange-port envelope, so it drops into the existing installation without bracket or piping changes.

• 40-degree bent axis with 7 pistons: High power density and a compact envelope, with global efficiency above 90% and about 200 N·m output at 400 bar continuous for space-limited heavy-duty ends.

• 100% simulated operating-condition testing: Each unit is run at rated pressure and speed under full-load simulation to verify volumetric efficiency, seal reliability, and bearing condition before shipment.

• Bi-directional operation and low noise: Gear-free internal design runs smoothly in both directions with low noise, suited to winch, swing, and fan drives with frequent direction changes.

• Cleanliness and seal control: Precision machining and contamination control protect volumetric efficiency and bearing life; case drain and shaft seal follow the series specification for long-term reliability.

Application Areas

• Construction machinery: Excavators, crawler cranes, truck-mounted cranes, hook-loaders (winch and swing drives)

• Industrial hydraulics: Injection molding machines, presses, hydraulic test benches

• Heavy and marine: Winches, deck machinery, marine auxiliaries

• Mining and forestry: Breakers, drills, harvester heads, mulchers

• Mobile equipment: Fan drives, conveyors, mixers

Expert Maintenance Tips

• Fluid cleanliness: Bent-axis motors are contamination sensitive. Maintain ISO 4406 cleanliness (suggest 18/16/13 or better; confirm with the official manual) because particles accelerate bearing and valve-plate wear.

• Case drain and back pressure: The case drain must return to tank, and case pressure (back pressure) must stay within the manual limit. Keep it as low as practical to avoid shaft-seal failure.

• Start-up bleeding: After first start or long shutdown, bleed slowly from the case drain or highest point to avoid cavitation and start-up dry friction.

• Shaft alignment: Align the motor shaft with the load shaft precisely. Do not exceed the allowable radial / axial shaft forces listed in the official “Acceptable forces applied to motor shaft” data.

• Rotation check: The M series is bi-directional, but actual direction follows porting. Confirm system flow direction against the required rotation before installation.

• Flushing valve (if specified): The Q1 port supports an external flushing valve (VBS 091180, for M32 to M108). In closed circuits, fit it to reduce return-oil temperature and contamination.

• Bolt torque: Tighten flange bolts in a cross pattern to the specified torque in stages to prevent flange misalignment, leakage, or bearing brinelling.
