Description:

Highland Heavy duty hydraulic motors features:

Highland Heavy Duty Hydraulic Motor is a mechanical actuator that converts hydraulic pressure and flow into torque and angular displacement (rotation). Highland hydraulic motors are designed for extreme conditions, ensuring reliable performance even under high pressure and heavy loads, making them indispensable in industries such as mining, construction, and heavy machinery manufacturing.

Highland HMF Series Technical parameter:

Notices:

Operating within Specifications: Even though Heavy Duty Hydraulic Motors are designed for high-pressure and heavy-load conditions, they should not be operated beyond their specified limits. Exceeding the motor's operating parameters can cause premature wear, reduced performance, and even motor failure. Always ensure the motor is used within the range of its intended application and according to the manufacturer's guidelines.

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

HMF70 Factory Production & Inspection Evidence

Prior to shipment each HMF70-21 passes through a documented production and inspection stage and is photographed on the factory floor; that evidence is recorded below.

Factory Evidence

• Hydraulic motor photographed on the factory floor before packing
• Housing and drive shaft visually checked prior to shipment
• Port and mounting arrangement verified to the HMF70 model specification
• Final inspection carried out per the product's technical requirements

Evidence Type: Factory Production / Visual Inspection

Application: Heavy machinery hydraulic drive

Product Status: Production / Pre-shipment Inspection

HMF70 Factory Performance Testing

All HMF70-21 motors are performance-tested on the closed-loop bench ahead of delivery. Component No. 02604110203003 was run on 2026/4/11 10:23 at 36.2 ℃, at a 70 mL/rev rated displacement, a 3200 r/min maximum speed and a 38 MPa maximum pressure (rated 35 MPa). Its recorded power-recovery ratio is 40 %.

HMF70 Recorded Test Data

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

The values listed above are unaltered from the factory test report; charge pressure is held at 1.1 MPa.

HMF70 Quality Control & Inspection

Each HMF70-21 goes through an identical inspection route. On completion of assembly it is bench-run on the closed-loop motor stand, where displacement, working pressure, speed, flow and torque are recorded, overall and volumetric efficiency verified, and leakage checked; approval is given only if all values meet specification.

HMF70 Application / Project Evidence

The HMF70-21 closed axial piston motor was produced for a Kyrgyzstan cotton harvester project. The order — referred to internally as “Variable Piston Pump for Kyrgyzstan” — totalled 60 units shipped to a Kyrgyzstan-based customer, with Shandong Highland Hydraulic Seiko Co., Ltd. as the manufacturer. Within this product the motor is applied to heavy machinery hydraulic drive through the closed-circuit hydrostatic transmission. The details below are from that delivery's project records.
