Flow Rate and Pressure: Select the appropriate screw pump model based on the required flow rate and pressure under actual operating conditions, ensuring that the pump's rated flow rate and pressure meet process requirements and have a certain margin.
Media Characteristics: Consider factors such as viscosity, corrosiveness, solids content, and temperature of the medium. For high-viscosity media, a screw pump with a large lead and large diameter is required; for corrosive media, corrosion-resistant materials should be selected; for media with high solids content, a screw pump with corresponding wear resistance should be selected.
Drive Method: Screw pumps have various drive methods, such as electric motor drive, diesel engine drive, and pneumatic motor drive. Select the appropriate drive method based on the power supply conditions and operating environment.
Installation Method: Select the appropriate installation method based on the installation space and process flow requirements, such as horizontal installation, vertical installation, or flange installation. Simultaneously, consider the pump's inlet and outlet connection methods and dimensions to ensure convenient and reliable connection with the piping system.
