GPT7MQL8 GPT SINGLE SCREW PUMPS
Model: GPT7MQL8
General Type Single Screw Pumps are powerful industrial transportation tools. Their unique structure enables application in diverse working conditions. They can convey high - viscosity, particle - laden, and corrosive media. These pumps offer stable flow rates, flexible adjustment, low energy consumption, and are easy to install and operate. They effectively address transportation issues in industries like chemical engineering, sewage treatment, and food processing, making them an ideal choice for cost - cutting and efficiency - boosting
● Transportation of high - viscosity media: The viscosity of the media ranges from 20,000 to 200,000 MPa·s, depending on the size of the pump.
● Transportation of media containing solid particles or fibers: The maximum particle size is 16 mm, the longest fiber length is 100 mm. The solid - phase content is generally 40%, and when the solid in the media is in powder form, it can reach 60% or even higher.
● Continuous and stable transportation: There is no periodic pressure fluctuation like that of reciprocating pumps.
● Low - agitation transportation: It does not damage the inherent structure of the media.
● Satisfying low - noise requirements.
