Turbo-pump is the heart of liquid propellant rocket engine. The turbine and pump normally share the same shaft and turbine drives the pump. The shaft has high temperature at one end and super low temperature at the other end, and rotates with high speed. The head of a single stage pump can be several thousand meters. The working conditions of the pump are very strict, since liquid propellants are highly inflammable and explosive. Since 1958，we have developed over a hundred rocket engine pumps. We have great breakthroughs in hydraulic model optimization, cavitation mechanism, inducer and centrifugal impeller matching, high load/high speed bearing, high PV/super low viscosity dynamic seal, and high speed gears. Those achievements laid solid foundation for industrial pump development, for example, high speed pumps, high pressure/abrasion-proof pumps and cryogenic pumps.
The special pumps are manufactured in our fabrication center which locates in Beijing Economic-Technological Development Zone. Every product is carefully tested on the advanced pump testing stand before shipment. Our customers give good remarks on the quality and performance of our pumps.
