& Accessories

The Rotary Lobe pumping principle uses two rotors.  These unmesh on the suction side to allow atmospheric pressure to draw fluid in and carry it around the perimeter of the casing, then the rotors mesh on the discharge side to force fluid out.  Bi-, tri- and multi-lobe rotor forms are available depending on the fluid to be pumped, with bi-wing rotors shown here.  The rotors are driven by a timing gear to prevent rotor-to-rotor contact.  The large voids created are particularly suited to highly viscous fluids, slurries and shear sensitive liquids.
