BMSY400 Gerotor Motor: Replaces Eaton/Danfoss/White; High Torque, Fast Delivery,

Product Specification

Product Overview

The BMSY400-E2-D-S-B is a heavy-duty, Low-Speed ​​High-Torque (LSHT) gerotor hydraulic motor with a displacement of 400cc (24.04 in³/rev). It features an advanced disc valve design and Geroler technology, renowned for high efficiency, reliability, and superior torque output. This product serves as a direct replacement for mainstream Western 400cc-class gerotor motors and is suitable for heavy-duty applications requiring robust power output, such as agricultural machinery, construction equipment, and material handling systems.

Compatible Brands and Models
The BMSY400 series is a direct replacement for corresponding models from the following Western brands:

Eaton Char-Lynn: Replaces 4000 Series (e.g., models 104-1383, 109-1236-006, 110-1082-006)

Danfoss: Replaces OMP400 and OMS400 Series (e.g., models 151-0318, 151F0605)

White: Replaces OMP-X 400 Series

M+S Hydraulic: Replaces MS400 Series

HydroTorq: Replaces HMS400 Series

The BMSY series utilizes industry-standard mounting interfaces (2-bolt/4-bolt flanges and various shaft options), ensuring direct drop-in replacement without the need to modify existing systems.

Key Advantages Over Western Brands
1. Significant Cost Advantage
While maintaining equivalent quality, the BMSY400 is priced 30%–50% lower than Western brands. With the market price of the Eaton Char-Lynn 109-1236-006 reaching as high as $2,945.57, the BMSY400 offers significant procurement cost savings for both distributors and end-users.

2. Faster delivery and more responsive service
Unlike European and American brands that often require weeks for delivery, the BMSY400 offers rapid delivery within 25–35 working days, effectively shortening project timelines and preventing equipment downtime caused by waiting for spare parts.

3. Equivalent performance, meeting international standards
Displacement: 400 cm³/rev (24.04 in³/rev)

Continuous Torque: 7,786 in-lb (approx. 880 N·m)

Continuous Pressure: 2,320 PSI (160 bar)

Continuous Speed: 185 RPM

Continuous Flow: 19.8 GPM (75 L/min)

Continuous Power Output: Approx. 11 kW

4. Structural design advantages
The BMSY series features an advanced design with the following characteristics:

Disc valve distribution structure: Automatically compensates for high-pressure conditions, ensuring high volumetric efficiency and long service life.

Geroler gear set design: Ensures smooth and reliable operation.

Optional tapered roller bearings: Capable of withstanding high axial and radial loads, suitable for harsh operating conditions.

Smooth low-speed startup: Low startup pressure ensures smooth and efficient operation.

Solutions for distributors and users

Solutions for users
1. Challenges in spare parts procurement
400cc-class gerotor motors from European and American brands are expensive (e.g., the Eaton 109-1236-006 sells for $2,945.57) and have long lead times, resulting in high costs associated with equipment downtime while waiting for parts. The BMSY400 provides a readily available alternative, significantly reducing equipment downtime.

2. Cost control pressure
Amidst fierce market competition, equipment manufacturers and end-users face constant pressure to reduce costs. The BMSY400 delivers equivalent performance at a more competitive price, helping users enhance their market competitiveness.

3. Demand for Low-Speed, High-Torque Performance
Equipment requiring low-speed, high-torque (LSHT) drive capabilities—such as agricultural and construction machinery—demands exceptional low-speed stability and torque output from the motor. The BMSY400 utilizes a Geroler gear set and disc valve design to meet the heavy-load requirements of such equipment.

Solutions for Distributors
1. Enhanced Customer Loyalty
Offering a cost-effective alternative helps build customer trust and reliance, particularly when customers are frustrated by the long lead times and high prices associated with OEM spare parts.

2. Optimized Inventory Turnover
Reasonable pricing and rapid delivery capabilities enable distributors to achieve higher inventory turnover rates for the same amount of capital invested.
