GQL/GQW Series HIGH SPEED PUMPS

V-FLO high speed pumps and compressors are developed on the basis of proven technology for space rocket engine turbo pumps running at 6000-70000rpm
Classification:
Description

Overview

V-FLO high speed pumps and compressors are developed on the basis of proven technology for space rocket engine turbo pumps running at 6000-70000rpm with a single stage discharge head up to 1500-2000m and it goes to 6430m for liquid at a working temperature of -253. Relying on space technology development of the past 50 years plus the continuous efforts and investments, numerous of achievements have been made in the fields of flow calculation, fluid model optimization, cavitation research, optimization design of inducer and impeller, pump vibration control system, material development, bearing design for heavy load and higher speed, mechanical seal systems with high PV value and ultra low viscosity, gearbox research, fabrication and manufacturing technologies, etc.

 

GQ-L Vertical Hi-Speed Pump

Suction and discharge flanges of GQ-L vertical high speed pumps are designed on the same centerline to enhance the stiffness and thermal-shock resistant capability. Besides, the piping load capacity is also increased.

GQ-W Horizontal Hi-Speed Pump

GQ-W are single stage, single-suction and overhung horizontal high speed pump series, which are mainly composed of electric motor, gearbox, pump assembly, lubrication system and baseplate. GQ-W series pumps have stable characteristic parameters, simple structures, high reliability and long serve life with easy maintenance. A backflow stabilizer is integrated into the GQ-WS/W7 pump system to improve the performances at low flow section and extend the flow regulating ranges. High speed thrust bearings are employed to bear suction pressure as high as 10MPa.
