What are the advantages of a rotary lobe pump?

Rotary lobe pumps are the mainstay of many hygienic fluid handling applications where gentle handling & cleanability are of utmost importance. These pumps have a wide range of displacements, good solids handling capabilities, and low shear characteristics across a wide range of product viscosities. The non-contacting pumping principle for RLPs means no metal-on-metal contact, limiting pump wear regardless of product viscosity.
