Lobe Pumps
Lobe pumps are valveless positive displacement pumps with meshing lobes not in contact with each other. For vacuum applications they are manufactured with extremely close tolerances. They are used in industries like pulp and paper, chemical, food, beverage, pharmaceutical and biotechnology. They are popular in these industries because they offer superb sanitary qualities, high efficiency, reliability, corrosion resistance and good clean-in-place and steam-in-place characteristics. Lobe pumps can handle solids ( e.g. cherries, olives etc.), slurries, pastes besides ordinary liquids. If wetted they offer selfpriming performance. A gentle pumping action minimizes product degradation. They also offer continuous or intermittend reversible flows and can operate dry for brief periods of time. Flow is relatively independent of changes in pressure, so that output can be kept constant by but slight changes in speed. Flows go up to about 1000 m³/h depending on product viscosity.(taken from: Wikipedia)
Lobe Pumps (B)
„B“ pump mounted on a base plate and connected with the driver by a flexible coupling- most versatile for all options.
Lobe Pumps (BE)
„BE“ with close-coupled driver in monoblock design, saves base plate and coupling - limited options, used in beverage industry.
Lobe Pumps (BF)
„BF“ executed like "B" - however- even the gearbox, housing the synchronous gear drive, is made of stainless steel, the pump housing being of wrought stainless (<1% ferrite!).
