AYDH Magnetic Liquid Nitrogen Pump
نظرة عامة على المنتج
AYDH Series Ultra-Low Temperature Magnetic Drive Pump The AYDH series is specifically engineered for cryogenic fluid handling. Both the pump body and machined components undergo rigorous deep-cooling treatment to ensure excellent low-temperature toughness and resistance to brittleness. Capable of sustaining pressures up to 5Mpa, it features specialized cryogenic bearings, high-precision impellers, and ceramic isolation shells. This series is the ideal solution for high-pressure, low-flow requirements in ultra-low temperature liquid transfer, offering exceptional reliability, long service life, and unmatched safety.
