Wuxi Haiyan High Pressure Pump & Valve Factory

The factory traces its establishment to 1992. Its company profile describes a traceability process introduced in 2012 that follows raw-material heat numbers, heat-treatment batches, machining inspection and component records. It also lists spectroscopy, hardness and tensile testing, and coordinate measurement among its inspection methods.

The 3DP40 product documentation distinguishes input-shaft speed from the slower pump speed and provides pressure-flow rows for different plunger diameters. This is useful for selecting a high-pressure package: changing the plunger diameter changes the available pressure and delivery, while the gear-driven arrangement determines the relationship between drive and pump speeds.
