Technical Parameter Trend Analysis

Manufacturing Process Flow of Triple Gear Pump (with Diagram)

To ensure optimum performance and reliability, the triple gear pump production incorporates premium alloys, robust engineering standards (e.g., ISO 19712, ANSI B93.7.1), and a rigorous quality regime.

Manufacturing Workflow

Raw Material Selection: Use of high-strength ductile iron, case-hardened steel or forged aluminum alloys (ISO 1083) for gears and housings.
Forging & Precision Casting: Gear shafts and housings are forged/cast to tight tolerances for enhanced durability.
CNC Machining: All critical surfaces, mounting faces, and gear profiles are machined via 5-axis CNC for high concentricity and low vibration.
Gear Tooth Hardening: Gears are treated (carburizing/nitriding) to 60-62 HRC, maximizing lifespan and fatigue resistance.
Cleaning & Assembly: Parts are ultrasonically cleaned and assembled in ISO 7 cleanrooms to mitigate contamination risks.
Hydraulic & Functional Testing: Every triple gear pump is subject to leak/flow/pressure test benches as per ISO 4409.
Final Inspection & Certification: Pumps are laser-marked with full traceability; supplied with ISO conformity and batch data sheets.
