Series Medium Pressure Screw Pumps CFHM from the company Allweiler They are designed to work with oils of various natures in hydraulic systems and other general industrial installations. Self-priming, used in applications with medium flow rates in a wide range of industry areas. The rotor design is based on three screws: one main drive screw and two idling screws for sealing. The rotation of the screws is carried out without mechanical action relative to each other, which allows you to maintain low noise and vibration.
The rotor frame and housing are made of aluminum, the moving parts of the rotor are made of nitrided steel, and the mechanical shaft seal. All structural components are perfectly balanced, axial loads are smoothed out, radial loads are excluded. Versions with a magnetic coupling are available to order for complete sealing of the drive unit. Flanged mounting, on request it is also possible to install on the paws.
