Notices:

Proper Installation: Ensure that the motor is properly installed according to the manufacturer's guidelines. This includes making sure all hoses are connected securely, that the motor is aligned correctly, and that the system pressure is within the recommended range.

Regular Maintenance: Regular maintenance is essential to keep your hydraulic motor running smoothly. This includes checking fluid levels, inspecting hoses and connections for leaks or damage, and cleaning the motor regularly.

Application:

Mixer truck: concrete mixer truck, cement mixer truck;

Coal mining machinery: scraper;

Industry: pharmaceutical machinery;

Transport vehicles: road rollers, concrete pump trucks, stabilized soil mixers

HMF70 Engineering Drawing

The HMF70-21 shares the HMF70/90 series motor drawing. Its output shaft is an involute spline at a 16/32 radial pitch and 30° pressure angle with 21 teeth and a dividing circle diameter of 33.34 mm. Four M12 bolts, 25 mm deep, fix the SAE flange. The leakage ports are L1 and L2; the speed-sensor port is 7/8-14 UNF-2B; and the flushing pressure measuring port and relief-valve taps are 9/16-18 at 15 mm depth. Both CW and CCW rotation are offered.

HMF70 Factory Production & Inspection Evidence

For every HMF70-21 that ships, the factory keeps a documented production and inspection record; the machine is photographed on the shop floor and the evidence is listed below.

Factory Evidence

• Hydraulic motor photographed on the factory floor
• Housing and drive shaft given a visual inspection before shipment
• Port and mounting configuration checked to the HMF70 model specification
• Closing inspection completed against the product technical requirements

Evidence Type: Factory Production / Visual Inspection

Application: Mobile crusher hydraulic drive

Product Status: Production / Pre-shipment Inspection

HMF70 Factory Performance Testing

Each HMF70-21 is bench-tested on the closed-loop rig before it is dispatched. Component No. 02604110203003 ran on 2026/4/11 10:23 at 36.2 ℃ at a rated displacement of 70 mL/rev, a maximum speed of 3200 r/min and a maximum pressure of 38 MPa (rated 35 MPa). The power-recovery ratio recorded is 40 %.

HMF70 Recorded Test Data

Factory bench results for the HMF70-21 motor, as recorded (component No. 02604110203003; 2026/4/11 10:23; 36.2 ℃; charge pressure 1.1 MPa):

These numbers are copied unchanged from the factory test report; charge pressure is held at 1.1 MPa.

HMF70 Quality Control & Inspection

All HMF70-21 motors follow one inspection sequence. After assembly the motor is bench-run on the closed-loop stand, recording displacement, working pressure, speed, flow and torque, checking overall and volumetric efficiency, and verifying leakage; sign-off requires every value to be within specification.

HMF70 Application / Project Evidence

The HMF70-21 closed axial piston motor came out of a cotton harvester project in Kyrgyzstan. The order — recorded internally as “Variable Piston Pump for Kyrgyzstan” — ran to 60 units and was delivered to a Kyrgyzstan-based customer, built by Shandong Highland Hydraulic Seiko Co., Ltd. On this product the motor serves the mobile crusher hydraulic drive in the closed-circuit hydrostatic system. The facts below are taken from that delivery's project records.

HMF70 Technical Documents

The HMF70 motor comes with a set of technical documents recording its performance ratings, test evidence and installation dimensions. The documents held for this product are listed below and are available to qualified buyers on request.
