Highland Heavy duty hydraulic motors features:

Highland Heavy Duty Hydraulic Motors are one of the most crucial components of hydraulic systems, responsible for converting hydraulic power into mechanical power. These motors are designed and built to withstand extreme operating conditions and heavy-duty applications, making them ideal for use in heavy equipment and machinery.

Highland hydraulic motor works by using hydraulic pressure to turn the motor's shaft, which then converts this energy into rotational motion. The power output of a hydraulic motor depends on several factors such as the motor size, pressure, flow rate, and displacement.

Notices:

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

Inspection Focus

HMF90 Factory Production & Inspection Evidence

Production and inspection of the HMF90-23 motor are recorded on the factory floor, giving a visual and procedural trace before dispatch. That evidence appears below.

Factory Evidence

• Actual hydraulic motor photographed on the factory floor
• Product housing and drive shaft visually inspected before shipment
• Port and mounting configuration checked against the applicable model specification
• Final inspection performed according to the product's technical requirements

Evidence Type: Factory Production / Visual Inspection

Application: Hydraulic motor systems

Product Status: Production / Pre-shipment Inspection

HMF90 Factory Performance Testing

Prior to shipment the HMF90-23 motor is run on the manufacturer's closed-loop test bench. For component No. 02603280203005 the test was performed on 2026/3/28 at 10:01, at 23.5 ℃, at a rated displacement of 90 mL/rev, 3200 r/min maximum speed and 38 MPa maximum pressure (rated pressure 35 MPa), with a 50 % power-recovery ratio recorded.

HMF90 Recorded Test Data

Recorded bench data for the HMF90-23 motor (component No. 02603280203005; 2026/3/28 10:01; 23.5 ℃; charge pressure 1.2 MPa):

All figures are the values printed on the original factory test report; charge pressure is held at 1.2 MPa throughout.

HMF90 Quality Control & Inspection

Each HMF90-23 passes through a fixed inspection route. Assembly is followed by a bench run on the closed-loop motor stand, where displacement, working pressure, speed, flow and torque are measured and the overall and volumetric efficiencies are verified, alongside a leakage check. A motor is approved only when all readings meet the standard.

HMF90 Engineering Drawing

For the HMF90-23 the drawing is the HMF70/90 series motor sheet. The drive shaft uses an involute spline of 16/32 radial pitch and 30° pressure angle. A SAE flange fixed by four M12 bolts (25 mm deep) is used; high-pressure ports A and B take 7/8-14 UNF-2B threads, L1 and L2 are leakage ports, the speed-sensor port is also 7/8-14 UNF-2B, and 9/16-18 pressure taps at 15 mm depth serve the flushing and relief valves. CW/CCW rotation is selectable.

HMF90 Application / Project Evidence

The HMF90-23 closed axial piston motor featured here belongs to the “Variable Piston Pump for Belarus” project. One hundred units were manufactured by Shandong Lande Hydraulic Precision Co., Ltd. and supplied to the Belarus customer for rye-harvester use, mounted in the machine's closed-circuit hydrostatic drive for both travel and harvesting motions. The project record of this delivery is summarised below.
