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
Factory Production & Inspection Evidence
Every drive system is assembled by Shandong Highland Hydraulic Seiko Co., Ltd. and released only together with its production and inspection documentation.
- Manufacturer: Shandong Highland Hydraulic Seiko Co., Ltd. (brand: Highland)
- Documented motor: MF20-21 closed-loop axial piston motor
- Documented Component No.: 02603250203005
- Documented project quantity: 20 units
- Closed-loop motor tested and inspection-recorded before release
The identification system allows a delivered unit to be matched to its production and test documentation.
Factory Performance Testing
Before dispatch, the closed-loop hydraulic motor is run on a factory test bench so that speed, pressure, flow, torque and efficiency are measured under load.
The supplied Closed-Loop Hydraulic Motor Test Report documents the MF20-21 motor (Component No. 02603250203005), tested at a temperature of 36.5 °C with a power recovery ratio of 10%. Rated displacement is 33.3 mL/rev, maximum continuous speed 3500 r/min and minimum continuous speed 500 r/min, with a rated working pressure of 35 MPa and a maximum (instantaneous) pressure of 42 MPa.
Testing is performed before release, not after delivery.
Recorded Test Data
The following points were recorded during the closed-loop test run of the documented unit.
| Speed (r/min) | Pressure (MPa) | Flow (L/min) | Displacement (mL/rev) | Torque (N·m) | Input Power (kW) | Output Power (kW) | Overall Efficiency (%) | Volumetric Efficiency (%) |
|---|---|---|---|---|---|---|---|---|
| 1337 | 4.3 | 47 | 35.2 | 27 | 3.8 | 3.4 | 89.1 | 100 |
| 1337 | 14.3 | 45.7 | 35.2 | 85 | 11.9 | 10.9 | 91.5 | 97.2 |

| 1308 | 30 | 44.2 | 35.9 | 181 | 24.8 | 22.1 | 89.1 | 94.1 |
Charge pressure: 1.5 MPa. Values are reproduced from the original test record and should be read together with the test bench's measurement and calculation method.
Quality Control & Inspection
Final quality control is based on documented identification, testing and dimensional verification.
- Product model and unit identification
- Closed-loop hydraulic performance testing
- Pressure and speed verification
- Flow and displacement recording
- Torque and power measurement
- Overall and volumetric efficiency recording
- Engineering interface verification
In the supplied test record the run is signed by an operator and an auditor (Operator 003, Auditor 002). The product documentation also states that units are produced under a strict quality-control system, and that any defective pump or motor is inspected before a response is issued.
