• lts structure is compact and simple.
• High performance copper alloy is used for volutes and impellers so as to guarantee the safety of pumpsin liquid oxygen working conditions.
• The pump has mature and reliable mechanical seal, strong anti-cavitation ability, long service life as wellas convenient instalation and replacement.
• A high strength and cryogenic stainless steel shaft is used.
• Static and dynamic balance tests are performed for the impellers and rotors so as to guarantee thestability of such rotors.
• A variable frequency and variable speed motor can be utilized to make the pump has a wider operation range.
• The inlet and outlet flanges are equipped with flexible connection and a liquid inlet filter; the pipelinevibration is small and the operation is stable.
• The labyrinth seal can also be configured,with a continuous operating life of 16000 hours
