Operating Principle for Rotary Lobe Pumps

Operating Principles of Rotary Lobe Pumps

There are Two (2) intermeshed rotors affixed to gear driven shaft. The shafts rotate in opposite directions. The rotating motion of the rotors create an expanding cavity on the suction side. Allowing fluids & solids to enter and fill the suction side of the pump. The rotors carry the fluid around the housing to the discharge side where it is expelled out of the pump by the closing cavity.

Rotary Lobe Pumps can:
*Reverse flow direction at any time.
*Run dry for extended periods of time.
*pump most any hard solid object that fits within the cavity between the rotor and casing.
*pump shear-sensitive liquids
*pump highly viscous liquids
*Can pull a suction lift over 20′.
The precise amount of lift depends on the viscosity of the liquid.
*Robust Rotary Lobe Pumps Designed for Viscous Liquids, Heavy Solids & Abrasives
Vogelsang is the market leader in the design and manufacture of rotary lobe pumps and systems. For over 80 years, we’ve been responsible for the major innovations and advances in positive displacement rotary lobe pump design.

There developments such as the multi-wing convoluted rotary lobe, adjustable housings and the InjectionSystem ensure long life and efficient operation.

Vogelsang Rotary Lobe Pumps are sold by: Flow-Tech Industies inc. Servicing the industrial market along the Texas Gulf Coast.
