从China供应商批发进口240 Volt Condensate Pump Dfbii80-50-240 — FOB条款

The DFBII80-50-240 is a horizontal single-stage condensate pump rated for 240 volt electrical supply, with an 80 mm suction and 50 mm discharge nominal diameter, and a 240 mm impeller trim or stage designation. Manufactured by Deyang Dongfang Yoyik Engineering Co., Ltd. in Sichuan Province, this unit is intended for extraction of condensed steam from turbine surface condensers in thermal power plants, including the Taliwang power station referenced in the source. The pump construction typically features a cast-iron volute, stainless-steel or bronze impeller, and a mechanical seal arrangement suited for handling hot, saturated water near vacuum conditions. Electric motor drive at 240V suggests either a special low-voltage site supply or a notation error that buyers must clarify, since standard industrial condensate pumps in China normally operate at 380V or 6kV.

Materials for condensate service demand corrosion resistance against oxygenated water and resistance to cavitation erosion at the impeller eye. Typical industry practice specifies ASTM A743 CF8M (316 stainless) or CB7Cu-1 for impellers, with duplex stainless steel as an upgrade for high-cycle operation. The pump shaft runs in sleeve bearings lubricated by the condensate itself or by external clean water, requiring careful alignment to prevent vibration and seal failure. Yoyik's listing groups this pump alongside numerous turbine and boiler spares, indicating it is sold as a replacement component rather than as part of a new engineered system. No performance curve, NPSH requirement, or efficiency grade is stated in the source data.

Target purchasers are power plant maintenance departments, MRO contractors, and spare-parts traders serving coal-fired and geothermal stations in Indonesia, the Philippines, and Africa where Taliwang-type units operate. The pump is applied downstream of the main condenser hotwell, feeding low-pressure feedwater heaters through a deaerator. Import buyers must confirm whether the 240V motor is single-phase or three-phase, the exact rotational speed, and whether the pump is supplied bare-shaft or close-coupled. Seal type, face material, and API Plan or ISO plan designation should be specified to avoid incompatibility with existing seal support systems. Packaging and preservation for long-lead spares storage should also be discussed with the supplier.

Deyang Dongfang Yoyik Engineering Co., Ltd. maintains its registered office at Huashan Plaza, Jingyang District, Deyang, Sichuan, China, postal code 618000. The supplier's platform profile shows a harbor trust tier with zero recorded response rate and zero average response hours, meaning no buyer interaction data is available to assess communication reliability. The company describes itself as a high-tech enterprise focused on power industry development, emphasising digital supply chain management and rapid spare-parts response. These claims are not independently verified in the listing; no patent numbers, research institute affiliations, or government high-tech enterprise certificate numbers are provided.

Yoyik's product breadth spans sealing components, hydraulic accumulators, solenoid valves, sensors, and turbine-specific hardware in addition to rotating machinery such as the DFBII80-50-240 pump. The source description positions the firm as capable of both standard spare supply and complex project customisation, yet no project references, client testimonials, or annual turnover figures are disclosed. Buyers should conduct due diligence through the Sichuan Administration for Market Regulation to confirm business licence status, and request a supplier capability survey covering machining equipment, balancing machine capacity, and in-house testing facilities for pump performance and NPSH verification.
