VERTICAL MULTISTAGE PROCESS PUMP GENERAL CHARACTERISTIC ● The VP pump is a multistage cryogenic Vertical Process Pump designed for continuous operations with all liquefied air gases. ● First heavy duty pump of this technology built in the early 90’s; the VP pump is today the reference for the world wide Air gas industry. ● The VP Pump can be kept in permanent cold stand-by, ready for an immediate start. ● The construction is the result of more than 40 years of CRYOSTAR experience in the field of cryogenic pumps, and the latest developments in low temperature materials & technologies. ● The...

MODELS AND SIZES ● VP X/115/: up to 12 stages

VERTICAL MULTISTAGE PROCESS PUMP HIGHLIGHTS Continuous duty: More than 600 references on the five continents running continuously. Legendary reliability: Preferred high duty, high performance process pumps by all major industrial gas companies Temperature insulation and stability: The VP is mounted on its “COLD BOX FLANGE” with a unique isolating flange in a “Composite” material for rigid mounting of the complete machine on the cold box and an efficient temperature break. Continuous cold stand-by: Closed and purged distance piece; this is the “Warm Box” execution avoiding any humidity...

VP SEALING SYSTEMS ● 2 or 3 chambers Labyrinths ● Dry gas seal: single or dual executions ● Mechanical seal in composite material LABYRINTH SEAL ● Dedicated to process applications ● Special design labyrinth to allow shaft contact in case of cavitations. ● Designed as a cartridge exchangeable with the other sealing system ● 3 chamber labyrinth standard design ensures a tight tolerance and high efficiency ● A low consumption of sealing gas ● Anti rotation system ● The Cartridge Design, easily removable, facilitates maintenance without dismounting the pump cold end. DRY GAS SEAL ● Dedicated...
