The basic structure of the basic structure of the centrifugal pump centrifugal pump is sincere composed of six parts, namely: impeller pump D12-25 * 4 multi-stage pump, shaft, bearings, seal rings D6-25 * 12 multi-stage pump, stuffing 1 centrifugal impeller is the core part of its speed and high output force, the impeller blades and played a major role in the assembly before the impeller through the static test. Requirements on inner and outer surfaces of the impeller smooth to reduce flow friction losses. The company's products using computer design and optimization process, the company has strong technical force, rich production experience and improve the detection means, so as to ensure stable and reliable product quality. Two, D-type multi-stage centrifugal pump Application: industrial and urban water supply and drainage, high-rise building pressurized water supply, garden irrigation, fire booster, long-distance water, heating, bathrooms and other warm and cold pressurized water cycle and supporting equipment, etc., in particular, for small boiler feed water. ? anguage RNU u east-language: ZH-CN; mso-bidi-language:???
