China 1" Sanitary Lobe Pump with Butter-Like Rotary Lobes

movable rotor pump for viscosity liquid (chocolate pump) 1" Sanitary Lobe Pump with butter-like rotary lobes
Rotary pumps are used in a variety of industries including, pulp and paper, chemical, food, beverage, pharmaceutical, and biotechnology. They are popular in these diverse industries because they offer superb sanitary qualities, high efficiency, reliability, corrosion resistance, and good clean-in-place and sterilize-in-place (CIP/SIP) characteristics.
These pumps offer a variety of lobe options including single, bi-wing, tri-rotary (shown), and multi-rotary. Rotary lobe pumps are non-contacting and have large pumping chambers, allowing them to handle solids such as cherries or olives without damage. They are also used to handle slurries, pastes, yogurt, cream, milk, shampoo and a wide variety of other liquids. If wetted, rotary pump offer self-priming performance. A gentle pumping action minimizes product degradation. Rotary pump 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. 1" Sanitary Lobe Pump with butter-like rotary lobes

How Rotary Pumps Work - movable rotor pump for viscosity liquid
Rotary 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 rotarys do not make contact. Rotary 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.

1. As the rotarys come out of mesh, they create expanding volume on the inlet side of the pump. Liquid flows into the cavity and is trapped by the rotarys as they rotate.
2. Liquid travels around the interior of the casing in the pockets between the rotarys and the casing -- it does not pass between the rotarys.
3. Finally, the meshing of the rotarys forces liquid through the outlet port under pressure.

Rotary Pump Usage and Applications -- movable rotor pump for viscosity liquid
Rotary pumps are frequently used in food applications because rotary pumps handle solids without damaging the product. Particle size pumped can be much larger in rotary pumps than in other sanitary pumps. Since the rotarys do not make contact, and clearances are not as close as in other pumps, this design handles low viscosity liquids with diminished performance. Loading characteristics are not as good as other designs, and suction ability is low. High-viscosity liquids require reduced speeds to achieve satisfactory performance. Reductions of 25% of rated speed and lower are common with high-viscosity liquids.
