Product Overview
The BMP-100P1AIIY10/T10 is the mid-displacement flagship model in the OMER BMP Series of geroler hydraulic motors, featuring a geometric displacement of 100 cm³/rev with roller-stator and disc valve distribution. The BMP Series is OMER’s core general-purpose low-speed high-torque orbit motor line, spanning 11 displacements from 36 cm³/rev to 500 cm³/rev, specifically engineered for medium-duty applications in agricultural machinery, construction equipment, municipal vehicles, and industrial drives.
The BMP-100P1AIIY10/T10 employs spool valve distribution with the valve integrated into the output shaft and driven by a cardan shaft, transmitting mechanical energy from the rotor set to the output shaft. This structure provides high axial and radial load capacity for continuous operation under heavy-duty conditions. This model is a direct drop-in replacement for Danfoss OMP 100, Eaton Char-Lynn equivalents, and M+S MP 100 models, with fully interchangeable mounting flange, shaft, and port locations — no hydraulic circuit or mechanical interface modifications required.
Every unit undergoes 100% simulated load-condition bench testing before shipment, covering continuous pressure, intermittent pressure, and the full speed range to ensure volumetric efficiency and output torque meet OEM standards.

Key Technical Advantages
1. Spool Valve Distribution with Integrated Design
The BMP-100P1AIIY10/T10 employs spool valve distribution with the valve integrated directly into the output shaft, driven rotationally by a cardan shaft. This integrated structure reduces part count and potential leakage paths compared to conventional separate valve plate designs, while improving distribution precision. The symmetry of spool valve distribution ensures identical performance in forward and reverse rotation, with no pronounced pressure shock or torque fluctuation during direction changes.
2. Tapered Roller Bearings for High Radial and Axial Load Capacity
The BMP Series output shaft is supported by tapered roller bearings capable of simultaneously withstanding significant radial and axial loads. This bearing configuration allows the motor to directly drive chain sprockets, gears, and other mechanisms subject to radial forces without additional bearing housings. The 25 mm cylindrical shaft with A8 × 7 × 32 mm parallel key (DIN 6885 standard) offers high shaft-end compatibility for easy interface matching with existing equipment.
3. Disc Valve Distribution with Automatic Wear Compensation
The BMP Series distribution structure features automatic wear compensation — even after extended operation, the distribution interface maintains tight contact, ensuring long-term volumetric efficiency stability. Advanced manufacturing processes guarantee Geroler roller-stator fit precision, enabling smooth operation at low starting pressure with high volumetric efficiency and long service life.
4. Compact Cast Iron Housing with High Power Density
The BMP-100P1AIIY10/T10 features a cast iron housing, achieving 100 cm³/rev displacement in a compact package with 10 kW maximum output power. The BMP Series covers 36–500 cm³/rev, and standardized flange and shaft options facilitate easy integration into existing hydraulic systems — an ideal replacement for OMP/MP Series OEM motors.

Expert Maintenance Tips
Installation Guidelines:
Before installation, verify system oil cleanliness meets NAS Class 9 or better. While spool valve distribution is more contamination-tolerant than disc valve designs, clean oil remains essential for long-term reliability. Install a 10μm filter upstream of the motor inlet.
The BMP-100P1AIIY10/T10 uses a 25 mm cylindrical keyed shaft (A8 × 7 × 32 mm). Ensure proper fit precision between the key and equipment-side keyway. Shaft alignment must be within 0.05mm using a flexible coupling.
The standard 2-bolt mounting flange pilot and equipment interface surfaces must be clean and flat. During initial commissioning, run at no more than 30% of maximum working pressure for at least 30 minutes of no-load break-in.
Note port orientation compatibility with hydraulic line connections during installation.
Operational Maintenance:
Normal operating oil temperature should not exceed 80°C. Monitor case temperature regularly; if abnormally high, prioritize checking internal wear or system internal leakage.
Use premium anti-wear hydraulic oil with viscosity maintained at 20–43 cSt at operating temperature.
Inspect volumetric efficiency every 2,000 hours or every 12 months. If efficiency drops by more than 10% of rated value, disassemble and inspect the spool valve assembly and rotor-stator set.
