Product Overview: DP Pump is a self Cbalancing multilevel boiler feed pump with single-suction, multievel and sectional structure. This series of pumps are suitbalbe for medium and low pressure boiler water feeding, and high-pressure boiler water feeding for thermal power plant, as well as high-lift water supply and drainage of factories and cities. They are used in transferring water or other liquid with similar physical and chemical properties to water. Temperature of media being transferred can vary from -20~160 Efficient energy-saving: Using advanced hydraulic model, independent R&D energy efficient products. Good centering of impeller and guid vane channel and efficiency will not significantly drop as balancing disc wears and rotor components move forward. No leakage of balancing water reduces loss of volume and improves pump efficincy and pump efficiency is on average 2-5% higher than normal DG pump. New structure: With symmetrically arranged impeller rotor components, axial forces generated by all levels of symmetrical impellers forces offset each other and automatic balancing of huge axial thrust within pump cavity can be realized without the balcancing disc structure. New technology: Unique throttling and pressure reduction devices, odd-lecel balancing device. High reliability: By canceling easy-failing balancing disc, pump reliability is greatly improved, maintenance frequency and maintenance cost are reduced. Low maintenance cost and long life time By adopting precision casting and unique throttling and pressure reducing devices for auxiliary support, pump vibration and noise are greatly reduced and service life is prolonged.
