Notices:
System Monitoring and Maintenance: A Hydraulic Drive System is a complex setup that requires regular monitoring and maintenance to ensure optimal performance and longevity. This includes keeping an eye on the hydraulic fluid levels and its condition, as contaminated or degraded fluid can affect the performance of the system. Regular inspections should also be carried out to detect any potential leaks or mechanical issues in the system. Moreover, it's crucial to follow the manufacturer's recommended maintenance schedule and guidelines for the specific components in the system. Ignoring routine maintenance can lead to decreased efficiency, increased wear and tear, and potential system failure.
Tank:
The tank level and the water present in the oil should be checked daily. If the tank must be filled with oil, filtered hydraulic oil must be used, and all water in the tank must be removed as required.
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
Shandong Highland Hydraulic Seiko Co., Ltd. manufactures these drive systems and records each motor unit so that it can be traced through production.
- 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
Records of this kind support the traceability of each unit through production and inspection.
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
Measured values taken from the closed-loop test bench are reproduced below for reference.
| 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 |

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
Quality control is maintained through product identification, performance records and interface 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.
