These are manufactured from good quality food grade SS-316 and are also available with steam jacket. Their Trilobe design & timing gear drive enhances the performance of the pumps and are popular in diverse industries because they offer superb sanitary qualities, high efficiency, reliability, corrosion resistance, and good clean-in-place and sterilize-in-place characteristics.

Lobe pumps are similar to external gear pumps in operation in that fluid flows around the interior of the casing. Unlike external gear pumps, however, the lobes do not make contact. Lobe contact is prevented by external timing gears located in the gearbox. Pump shaft support bearings are located in the gearbox, and since the bearings are out of the pumped liquid, pressure is limited by bearing location and shaft deflection.

Rotary lobe pumps are non-contacting and have large pumping chambers, allowing them to handle solids such as cherries or olives without damage and are also used to handle slurries, pastes & a wide variety of other liquids. They also offer reversible flows and can operate dry for long periods of time. Flow is relatively independent of changes in process pressure, so output is constant and continuous.

Applications

Useful for pumping & transfer of Chocolates, Jams, Jelly, Syrups, Paints, Dyes, Polymers, Soaps, Surfactants, Adhesives, Rubber, Dairy Products, Chutny, Fruit Pulp, Yogurt, Gelatin, Glucose, Glycerine, Honey, Ketchup, Sorbitol, Soya Sauce, Toothpaste etc.
