Rotary
lobe pumps are used widely in the chemical food, pulp and paper, beverage and
pharmaceutical industries. Rotary lobe pumps are popular in these industries
because they offer reliability, high efficiency, sanitary qualities and good
clean and steam in place characteristics. Rotary lobe pumps can quite easily
manage a variety of liquids and solids. Rotary lobe pumps work in a similar
fashion to external gear pumps, in that fluid flows around the interior of the
casing, but unlike external gear pumps, the lobes do not make contact. Rotary
lobe pumps are commonly used in food applications, as they can handle solids
without damaging the product. The flow in rotary lobe pumps is relatively
independent, so output is constant and continuous.
