AP-R+ Rotary Lobe Pumps
The heating jacketed lobe pumps can be used to pump chocolate, candy, gum and other materials which will easily freeze at room temperature or deteriorate at high temperatures. The heating jackets can effectively help resolve all the poor flow, solidification and deterioration problems....

Application
Sanitary lobe pumps are frequently used in applications where particle sizes are larger than what other positive displacement pumps (PD pumps in short, given volume liquid between two meshes) can handle without damaging the products.
- Dairy: cream, ice cream, margarine, curds, butter, soft cheese, yogurt
- Bakery: yeast, dough, fruit filling, fats and oils
- Meats: sausage filling, fats, broths, pet food
- Canned foods: baby food, soups stews, ketchup, pudding, dressings, mayonnaise, jams and jellies
- Beverages: beer, mash, wort, fruit juices, fruit concentrate
- Candy: sugars, chocolate, cocoa butter, corn syrup, gelatin
- Flavorings: syrups and concentrates
- Cosmetics: creams, lotions, jellies, shampoos, emulsions, toothpaste
Advantages
- Pass medium solids
- No metal-to-metal contact
- Superior CIP/SIP capabilities
- Long term dry run (with lubrication to seals)
- Non-pulsating discharge
Operating Principle:
A typical sanitary lobe pump includes two lobe rotors which can rotate in opposite directions (one clockwise and the other counterclockwise) in the casing without contact.
During rotation, the lobes create an expanding space on the inlet side, through which the liquid at the inlet could flow into the cavity in the casing.
Liquid does not travel though the inter-space of the lobes, but the areas between the lobes and the casing.
When the lobes rotate back into mesh, the liquid in the casing would be forced out through the outlet under pressure.
