Rotary Lobe Pumps from Viking Pump

Rotary lobe pumps use timing gears to eliminate contact between the rotors, which allows their use on non-lubricating fluids.  Various rotor forms are available, including bi-wing (shown at left) and multi-lobe options (shown below).  These pumps offer both sanitary/hygienic designs which meet 3A and EHEDG standards, and industrial designs with bearings on both sides of the rotors for higher pressure capabilities.
