Rotary Lobe Pumps Pulsation Dampeners / Rotary Piston
Lobe Pumps (aka "rotary piston" - In German), popular for high viscosity ("non Newtonian") liquids, often need
suction stabilizers, of the Flo-Thru type to ensure uninterrupted filling. Rotary Lobe Pumps have improved performance, use less power, and produce smooth flow when connected to pulsation-dampeners. Though relatively pulseless Tri and Bi Lobe Pumps show pulsation from the compression in the lobe root of the rotary pump. As rotary lobe pump use is often for high viscosity pulsation-dampeners with only one connection cause pressure pulses because of the energy required to force reciprocation up & down a "T" branch. All these recommendations are for "Flo-Thru."
