application
DFN series hygienic self-priming pump has strong self-priming ability and can realize gas-liquid mixed transportation. It can be widely used in food, beverage, medicine, chemical industry and other fields, especially in the cleaning-in-place system (CIP) for return flow Pump. However, the self-priming pump also has great shortcomings: the noise is high, especially the large-flow self-priming pump: Wangte pump has introduced international advanced technology, and installed a noise reduction device in the pump body, which can significantly reduce the noise of the self-priming pump.
standard design
DFN series sanitary self-priming pump consists of the following parts: standard motor, pump body, impeller, pump cover, pump shaft and sanitary mechanical seal. DFN series hygienic self-priming pumps have a stainless steel motor guard and four adjustable stainless steel feet.
shaft seal
DFN series sanitary self-priming pump can be equipped with a sanitary single mechanical seal or a water flush double mechanical seal according to the needs of users. The friction surface materials of the mechanical seal are: graphite to silicon carbide, silicon carbide to silicon carbide or tungsten carbide to tungsten carbide, etc.
