Import 3 Screw Pump 3gr30x4w2 Customized — Buy in wholesale FOB from Supplier in China

The 3GR30X4W2 customized three-screw pump is a positive-displacement rotary pump built around three precision-machined helical rotors, one power rotor and two idler rotors, running with extremely tight clearances inside a hardened liner. The 3GR designation indicates a medium-pressure, triple-screw configuration commonly used in hydraulic and lubrication systems; the 30 mm nominal rotor diameter and 4W2 variant code denote a specific displacement and mounting arrangement tailored to customer requirements. Deyang Dongfang Yoyik Engineering Co., Ltd. supplies this unit as part of its power-equipment spare parts portfolio, drawing on established resources for pneumatic and hydraulic components both domestically and internationally.

Three-screw pumps of this class typically employ alloy steel rotors with nitrided or chrome-plated surfaces to resist adhesive wear, paired with a cast-iron or steel housing liner that maintains dimensional stability across the rated temperature range. The 3GR series is designed to handle lubricating fluids with viscosities from 3 to 380 mm²/s, with standard operating pressures up to 2.5 MPa and flow rates dependent on rotational speed and pitch geometry. In power-plant applications, these pumps circulate turbine oil, feed hydraulic control systems, and supply lubrication to generator bearings, where pulsation-free flow and minimal shear on the fluid are critical.

Buyers in power generation, metallurgy, and mining sectors source the 3GR30X4W2 for retrofit and maintenance of existing lubrication skids, hydraulic power units, and boiler-turbine auxiliary systems. Customization covers port orientation, shaft extension, coupling arrangement, and seal configuration to match legacy installations. The listing does not state an MOQ, lead time, or Incoterm; importers should confirm these directly with Deyang Dongfang Yoyik Engineering, along with whether the unit is supplied with a test certificate, performance curve, or spare rotor set.

Deyang Dongfang Yoyik Engineering Co., Ltd. is based at Huashan Plaza in Jingyang District, Deyang, Sichuan Province, China, postal code 618000. The company operates under a Harbor trust tier on the platform, with a response rate currently shown as 0.00 percent and no recorded average response hours, which means prospective buyers should expect to initiate contact and allow time for reply. Its business centres on power-equipment spare parts, covering generators, steam turbines, boiler accessories, and allied pneumatic and hydraulic components.

The firm's stated scope includes brand resources for well-known domestic and international pneumatic and hydraulic component manufacturers, positioning it as a trading and engineering supplier rather than a single-brand OEM. The listing does not provide year of establishment, registered capital, factory floor area, headcount, revenue figures, named clients, or ISO certification numbers. Buyers should verify supplier credentials, quality-management system registration, and any OEM authorizations directly before placing orders.
