Description:

Highland Heavy duty hydraulic motors features:

Highland Heavy duty motors is a typical volumetric fluid machine, driven by the prime mover, converting the input mechanical energy into the pressure energy of the liquid, and then inputting it into the system in the form of pressure and flow. Highland Heavy duty motors is the power source of the hydraulic system.

The service life of Highland heavy duty hydraulic motorsp is related to the usual maintenance, the quantity and quality of the hydraulic oil, and the cleanliness of the oil. It is also an effective way to prolong the life of Highland plunger pump to avoid the wear and tear of the friction pair of the plunger pump caused by the particles in the oil. The higher the cleanliness of the hydraulic oil, the longer the service life of Highland hydraulic pump.

Hydraulic oil

The suitable replacement period for hydraulic oil in a sealed tank system is 2000 hours, and more often if the hydraulic oil is contaminated with water or other external materials or subjected to abnormal operating conditions.

As a general recommendation, the 10µ inlet oil filter should be replaced every spring or every 1500 hours (whichever occurs first) on a sealed tank system, or in an open tank system with an air filter fill cap. The oil filter should be replaced every 500 hours.

Heat Exchanger

The heat exchanger core and fins are kept clean at all times for maximum cooling and system efficiency, and the exterior of the heat exchanger is checked daily for blockages and cleaned as needed.

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 is covered by the HMF70/90 series motor drawing. Its output shaft is an involute spline of 21 teeth at a 16/32 radial pitch and a 30° pressure angle, with a dividing circle diameter of 33.34 mm. The SAE flange is secured by four M12 bolts, 25 mm deep. 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, 15 mm deep. Clockwise and counter-clockwise rotation are both available.

HMF70 Factory Production & Inspection Evidence

Each HMF70-21 completes a recorded production and inspection step before it is released for shipment, with the unit photographed on the factory floor. The evidence is summarised below.

Factory Evidence

• Motor unit photographed on the production floor prior to packing
• Housing and shaft inspected visually ahead of shipment
• Ports and mounting interface verified against the HMF70 specification
• Final inspection performed to the product's technical requirements

Evidence Type: Factory Production / Visual Inspection

Application: Mobile crusher hydraulic drive

Product Status: Production / Pre-shipment Inspection

HMF70 Factory Performance Testing

Before delivery, each HMF70-21 passes a closed-loop bench test. Unit No. 02604110203003 was tested on 2026/4/11 10:23 at 36.2 ℃ at the 70 mL/rev rated displacement, 3200 r/min maximum speed and 38 MPa peak pressure (rated 35 MPa), with a power-recovery ratio of 40 %.

HMF70 Recorded Test Data

Recorded bench output for the HMF70-21 motor (component No. 02604110203003; 2026/4/11 10:23; 36.2 ℃; charge pressure 1.1 MPa):

Values are reproduced without alteration from the factory test report; charge pressure remains at 1.1 MPa.

HMF70 Quality Control & Inspection

Every HMF70-21 motor passes through the same inspection routine. Once assembled it is run on the closed-loop motor stand, where displacement, working pressure, speed, flow and torque are logged, overall and volumetric efficiency are confirmed, and leakage is checked; the unit is approved only when all readings sit within specification.

HMF70 Application / Project Evidence

The HMF70-21 closed axial piston motor was built for a cotton harvester programme in Kyrgyzstan. The project — held internally under the name “Variable Piston Pump for Kyrgyzstan” — comprised 60 units delivered to a Kyrgyzstan-based customer, manufactured by Shandong Highland Hydraulic Seiko Co., Ltd. On this product the motor is applied to the mobile crusher hydraulic drive within the closed-circuit hydrostatic transmission. The information below is drawn from that delivery's project records.
