Low Speed High Torque Hydraulic Motor BMER-2-200-FS-RW

Hello, we are Shijiazhuang Hanjiu Technology Group, a professional manufacturer of hydraulic motors in China. Our products cover a full range of hydraulic motors, including orbit motors, gerotor motors, gerotor motors, low-speed high-torque motors, disc valve motors, and spool valve motors.

Our motors, under the Hanjiu brand, can completely replace or match mainstream international brands such as Danfoss, White, Parker, Eaton Char-Lynn, M+S, DANA, and BREVIINI. They are suitable for various applications including agricultural machinery, construction machinery, aerial work platforms, forestry machinery, and industrial automation equipment.

I. Why can distributors, equipment manufacturers, and repair shops purchase from us?

1. Distributors: High Profit Margins, Fast Inventory Turnover

Our motors are priced at only 30%–50% of European and American brands, leaving ample profit margins for distributors. Meanwhile, we offer a wide range of displacements (e.g., the BMER series 80-500cc/rev), providing a one-stop solution for various needs from light agricultural machinery to heavy-duty construction machinery. We also offer OEM customization services, supporting the creation of independent brands and helping distributors build long-term customer loyalty.

2. Equipment Manufacturers (OEMs): Reduced Procurement Costs, Optimized Supply Chain

Equipment manufacturers prioritize reliable, consistent, and timely core components. Our motors are fully compatible with European and American brands in terms of dimensions, mounting flanges, shaft extension types, torque curves, and pressure ratings, allowing direct replacement of existing configurations without modifying the main unit design. We support customization based on provided drawings—non-standard shaft diameters, special oil port locations, high-pressure seals, corrosion-resistant coatings, and alternative flange designs can all be adjusted as needed, helping you reduce procurement costs and shorten supply chain response time.

3. Repair Service Provider: Complete Parts Supply, Fast Delivery

The biggest concerns in the repair market are unavailability of parts, long lead times, and opaque pricing. We provide a complete range of easily worn parts, such as sealing kits and friction plate assemblies. Standard motors are shipped within 25 days, and some items are readily available with rapid response, helping repairers significantly reduce equipment downtime. Compared to the lengthy after-sales cycles (60-90 days) of European and American brands, we have a significant advantage in timeliness.

II. What are our advantages compared to European and American brands?

Advantage 1: Significant Price Advantage, Leading Cost-Effectiveness

Through the industrial cluster effect and vertically integrated supply chain (casting, CNC precision machining, gear grinding, and integrated sealing parts), our production costs are significantly lower than those of European and American manufacturers. Hydraulic motors with equivalent performance are priced at 30%-50% of European and American brands, without compromising quality.

Advantage Two: Comprehensive Technical Parameter Comparison, Seamless Interchangeability

Our motors are fully compatible with international brands in terms of size, displacement, torque curve, and pressure rating, and can directly replace corresponding models from brands such as Danfoss, Eaton Char-Lynn, Parker, White, and M+S. A complete cross-reference table between different brands is available, eliminating the need for complex technical adjustments during procurement and replacement.

Advantage Three: Comprehensive Product Range, Wide Application

Our product range covers the full series including OMM, OMP, OMR, OMS, OMT, OMV, BM3, BMR, BMRS, BMS, BMP, BMH, BMT, BMV, BME2, BMER, BMK2, BMK4, BMK6, and BMK10, with displacements ranging from 8cc/rev to 975cc/rev. Equipped with DIN or SAE standard shaft extensions and flanges, they can flexibly adapt to different working conditions. Both gerotor (internal gear ring type) and geroler (roller type) structures are available. The geroler structure, by using rollers instead of direct tooth surface contact, transforms sliding friction into rolling friction, resulting in superior low-speed stability and service life, making it particularly suitable for heavy-duty continuous operation.

Advantage Four: Short Lead Time and Stable Supply

European and American brands often have supply cycles of 60-90 days, significantly affected by global supply chain fluctuations. Leveraging China's well-developed hydraulic component manufacturing ecosystem and our own stable production capacity, we offer standard models with 25-day delivery, and bulk orders can be arranged for rapid production upon negotiation. For OEM manufacturers, this translates to shorter production wait times and faster market response.

Advantage Five: Complete Certifications, Seamless Export

Our products are ISO 9001 quality management system certified and meet international standards such as CE, allowing for smooth export to global markets including Europe, North America, Southeast Asia, South America, the Middle East, and Africa. We have accumulated extensive export experience, and our documentation, packaging, and logistics can accommodate the procurement processes of international clients.

III. Main Application Areas of Cycloidal Hydraulic Motors Cycloidal hydraulic motors, characterized by low speed and high torque, are widely used in the following areas:

Agricultural Machinery: Combine harvesters, tractors, sprayers, seeders, fertilizer spreaders, balers, corn header drives, disc harrows, rotary tillers, etc.

Construction Machinery: Concrete mixers, road rollers, cranes, mini excavators, loaders, material handling equipment, vibratory compactors, graders, drilling rigs, etc.

Aerial Work Platforms: Scissor lifts, articulated boom lifts, etc. Self-propelled drive for aerial work platforms

Forestry machinery: logging machines, timber harvesters, brush cutters, wood chippers

Industrial equipment: conveyors, mixers, winches, hoists, injection molding machine mold adjustment, textile machinery, printing machinery, commercial washing machines, sweepers/floor scrubbers

Marine vessels: ship deck machinery, winch drives, steering gear systems, anchor winches

Vehicle propulsion: off-highway dump trucks, special vehicle drives, tracked chassis walking systems

IV. Correct Use of Motors

1. Selection Considerations

Before selecting a motor, please confirm that the following parameters match: displacement (cc/rev), rated pressure (MPa), maximum pressure, torque requirement (N·m), speed range (rpm), mounting flange type, output shaft type (DIN/SAE standard, flat key, spline), and oil port specification (G thread/UNF thread/SAE flange). Larger displacement generally results in higher torque, but also a lower maximum speed. For example, the BMR-50 (51.7cc/rev) has a torque of approximately 93 N·m, while the BMR-400 (401.9cc/rev) has a torque of approximately 380 N·m. The appropriate displacement must be selected based on the actual load requirements of the equipment.

2. Installation Requirements

Before installation, ensure the piping and system are clean, and prevent foreign objects from entering the motor. During installation, tighten the connecting bolts to the specified torque value and apply an appropriate amount of thread-locking adhesive to prevent loosening due to vibration. The output shaft and the load coupling should be concentric to avoid uneven loading that could lead to premature wear of the shaft seal or bearings. The oil drain port must return to the oil tank separately, and the back pressure of the drain oil must not exceed 0.5 MPa (requirements may vary slightly depending on the model); otherwise, the shaft seal may be damaged.

3. Initial Use and Bleeding

Before starting a newly installed motor for the first time, fill the motor cavity with hydraulic oil through the oil port to avoid dry running. After starting, run the motor under low load for several minutes to allow the system to fully bleed and reach operating temperature. Before restarting after a long period of shutdown, bleed air should also be performed.

4. Daily Operation and Maintenance

Regularly check the oil level and cleanliness. It is recommended to use hydraulic oil that meets ISO 4406 standard grade 18/16/13 or higher (NAS 9 grade or better). Change the hydraulic oil and filter every 500-1000 hours depending on equipment operating conditions. When not in use for extended periods, it is recommended to periodically start the equipment and run the motor for a few minutes to prevent aging of internal seals or valve core jamming.
