Quality is the Core Competitiveness of Hydraulic Gear Pumps

Are inferior hydraulic gear pumps causing costly downtime for your machinery?As a core component of industrial equipment, hydraulic gear pumps’ performance reliability and durability directly impact operational efficiency and safety. When selecting suppliers, price is just the starting point—what truly matters is their quality control system and stable supply chain to ensure long-term reliability.

Quality control system-End-to-End Precision Monitoring

We ensure the pressure resistance and sealing performance of each hydraulic gear pump through 7 core links (7-Step Process), completely solving the risk of “quality fluctuation”:

1. Raw Material Inspection

Alloy steel spectral analysis (composition deviation ≤ 0.5%) + hardness test (HRC 58-62 meets the standard)

2. CNC machining

DMG five-axis machine tool processing, gear accuracy can reach ISO 1328-1 CLASS 3 standard

3. Heat treatment

Vacuum carburizing and quenching, surface hardness uniformity error < ± 1.5%

4. Dynamic Sealing Test

Simulate 3000 hours of extreme working conditions, oil leakage rate < 0.2%

5. Pressure Burst Test

Pressurize to 1.5 times the rated value, and continue for 30 minutes without deformation

6. Full life cycle traceability (Full Traceability)

Laser engraving records production batches, inspection personnel and test data

7. 3rd-Party Certification

Random sampling of each batch for inspection, passing TÜV, obtaining SGS report

Quality Testing Equipment - Full Process Validation

We use the industry’s cutting-edge testing equipment (Advanced Testing Systems) to ensure that each hydraulic gear pump passes three core tests before leaving the factory:

High-Pressure Sealing Tester:

Simulates 1.3 times the rated pressure (up to 42MPa) for 2 hours, Zero-Leakage Certified.

Dynamic Flow Analyzer:

Real-time monitoring of flow fluctuations (error <±1.5%), ensuring efficiency ≥95%.

Noise & Vibration Chamber:

Complies with ISO 3744 standards, operating noise ≤68dB(A), extending equipment life.

Why Trust Us?

100% full inspection coverage (not random inspection) to eliminate the risk of defective product delivery

Each device comes with a traceability code, and the data is transparent and traceable

Third-party laboratory review (such as SGS) to ensure international recognition of the results
