Usage Guide

Dear consumer,

In order to make the hydraulic motor work in optimal situations, we sincerely recommend the following:

1. A simultaneous max speed and max pressure is not recommended.

2. The motor can be used in parallel or series. But the installation of a drain line is necessary when back pressure is over 5 Mpa (72 PSI).

3. Filtering and oil cleanliness: a return filter should be installed in the system with a rating in the range of 10~30 um. The ISO level of the oil is to be no more than 19/16.

4. The optimum operating situation should be at the 1/3~2/3 of the continuous operation.

5. Make sure the motor is always filled with oil before operating.

6. In order to obtain longer life of the motor, we recommend to operate the motor at first for 30 minutes under 30% of rated pressure.

7. Maximum operating temperature: 80°C.

8. Recommended fluid: Anti-wear type of hydraulic oil. Viscosity: 37-73cst. Filtration: ISO19/16

1 Nm = [8.851 lbf.in] 1 cm3 = [0.061 in3] 1 N = [0.2248 lbf ] 1 L = [61 in3] 1MPa = [10 bar] 1 L = [0.22 UK gal] 1 bar = [14.50 psi] 1 L = [0.264 US gal] 1 mm = [0.0394 in] °F = [1.8 °C + 32]

HMM series motor is a mini-motor with high speed capabilities, very compact design, spool valve, economical type motor.

CHaraCTeriSTiC FeaTureS

• Compact design of spool and gear set, which provide mini volume, high power and low weight.

• Credible design for shaft seal , which can bear high pressure and be used in parallel or in series.

• Direction of shaft rotation and speed can be controlled easily and smoothly.

Notes 1. Continuous data: The Max. Value of operating motor continuously. 2. Intermittent Data: The Max. Value of operating motor is 10 % per minute. 3. A simultaneous max. RPM and max. pressure is not recommended. 4. The Conversion Factors are on page 4. 5. Optimum operating situation should be at the 1/3~2/3 of the continuous operation.

BM2 series motor is a medium, spool valve type motor, that can bear higher pressure than BM1.


• It adopts the gerolor design. Has higher efficiency than our BM1 series.

• Credible design for shaft seal, which can bear high pressure and can be used in parallel or in series application.

• Direction of shaft speed can be controlled easily and smoothly.• Best efficiency and economy in medium load applications.

The BM3 is a spool valve with 2 radial ball-bearing type motor that can bear bigger radial force.


• Supported by double ball-bearing, the shaft can carry bigger radial force than our BM2 motor.

• Credible design for shaft seal, which can bear high pressure and be used in parallel or in series.


• Best combination of efficiency and economy in medium duty applications.

BM3 Motor

Notes 1. Continuous data: The Max. Value of operating motor continuously. 2. Intermittent Data: The Max. Value of operating motor is 10 % per minute. 3. Simultaneous max. RPM and max. pressure are not recommended. 4. The Conversion Factors are on page 4. 5. Optimum operating situation should be at the 1/3~2/3 of the continuous operation.

The BM5 is a large volume, disc valve, high pressure motor with radial bearings design and can bear greater load.


• Advanced design in disc distribution flow, which can provide better performance at low speed.

• The valve can automatically compensate for the wear, so the volumetric efficiency is higher.

• Double taper roller bearings permit high radial loads. The motors can be used on heavier vehicles in traction drive applications.

4K Motor

The 4K is a large volume that is between our BM5 and BM6, disc valve, high pressure motor with radial ball-bearings design and can bear greater load.



• Advanced design in disc distribution flow,which can provide improved performance at low speed.

• The valve can automatically compensate for wear, so the volumetric efficiency is higher.


Notes 1. Continuous data: The Max. Value of operating motor continuously. 2. Intermittent Data: The Max. Value of operating motor is 10 % per minute. 3. A simultaneous max. RPM and max. pressure is not recommended. 4. The Conversion Factors is on page 4. 5. Optimum operating situation should be at the 1/3~2/3 of the continuous operation.

BM6 Motor

The BM6 is a large volume, disc valve, high pressure motor with a radial ball-bearings design and can bear greater load and has higher torque rating than our BM5.


• The motor can be used in high pressure, so it’s max. torque is higher than our BM5 motor.

• Advanced design in disc distribution flow, which provides improved performance at low speed.

BMV Motor

The BMV is a disc valve, high pressure motor, with radial ball-bearings design and efficient performance that can bear greater load than BMT. Its volume is bigger than BMT.


• The motor can be used in high pressure and high torque.• Advanced design in disc distribution flow,which can

provide improved performance at lower speeds.• The valve can automatically compensate for wear, so the

volumetric efficiency is high.• Double taper roller bearings permit high radial loads.

The motors can be used on heavier vehicles in traction drive applications.

Main Specification

Notes 1. Continuous data: The Max. Value of operating motor continuously. 2. Intermittent Data: The Max. Value of operating motor is 10 % per minute. 3. A simultaneous max. RPM and max. pressure is not recommended. 4. The Conversion Factors is on page 4. Please consult it. 5. Optimum operating situation should be at the 1/3~2/3 of the continuous operation.
