    Project Introduction

    The waste heat recovery project for Henan-based Coal & Coke Co., Ltd., a long-standing client, is a key initiative for their green production. The stable operation of the bubble system directly impacts efficiency, and the bubble feedwater pump must be perfectly suited to handle high-temperature, outdoor, and complex operating conditions. China United Pump Industry With years of Boiler feedwater pump Technical expertise, customization capabilities, and extensive engineering application experience enabled us to successfully undertake the equipment supply task for this project.

     

    Self-balanced boiler feedwater pump

     

    I. Project Requirements and Core of Deal Closing

    The customer previously experienced issues because the standard feedwater pump was incompatible. 104 ℃ deoxygenated water is being transported, and sealing failures have been occurring frequently. Zhonglian Pump Industry has assembled a technical team to conduct an on-site inspection, confirming that the equipment is installed outdoors (requiring it to withstand -17.3 °C to 39.5 °C temperature difference), and customized DG12-80 × 10P Type Multistage centrifugal pump The plan focuses on optimizing the sealing structure and material selection. Ultimately, through precise adaptability and a trusted reputation, we achieve 3 Taiwan bubble feedwater pump complete supply cooperation.

    II. Core Configuration and Supply Details

    Zhonglian Pump Industry provides 3 Taiwanese bubble feedwater pump and complete set of components (including the pump body, YBX3-280M-2 Motor types, diaphragm couplings, protective covers, inlet and outlet flanges, mounting accessories, and random spare parts)—the key parameters are as follows:

    Model: DG12-80 × 10P (Self-balancing multi-stage boiler feedwater pump), delivering 104 ℃ Deoxygenated water;

    Imports: 0.1–0.14 MPa(g) Pressure, fluid density 955kg/m ³；

    Performance: Traffic 12m ³ /h , Head of Pump 800m Cavitation margin 3.2m , Rotational speed 2950r/min；

    Protection: Motor 380V/110Kw ( IP55 ), vibration ≤ 0.065mm Noise ≤ 85 dB(A) ；

    Material: Impeller / Guide Vane 2GR13 • Pump body made of cast steel, shaft 40GR , equipped with high-temperature-resistant modular mechanical seals.

    III. Operating Conditions and Application Effects

    The equipment is installed in an outdoor area and must withstand extreme temperature fluctuations, 104 ℃ Deoxygenated Water Transportation and 24 The equipment has been running steadily for several months now, meeting the demand for continuous, hour-long operation. During this time, both flow rate and head have remained perfectly stable, with no leaks detected in the seals. Vibration and noise levels also meet industry standards. Recently, a customer shared feedback with our Customer Service Department: "The Zhonglian pump has effectively resolved our longstanding troubleshooting issues, significantly reducing operational and maintenance costs. It truly is an excellent product—and we’d be happy to recommend it to our peers if the opportunity arises."
