Rotary Lobe Pumps

Rotary Lobe Pumps

Lobe pumps (positive displacement) are similar to external gear pumps, operated by two Y or I shaped lobes which are aligned vertically rotating within a pump casing. The timing gears located within the gearbox, transfer the energy from the drive shaft to the driven shaft, synchronizing the rotors such that they rotate without contacting each other. The rotors are located on shafts and are mounted within the gearbox and supported by bearings. Outlets and Inlet of the pump can be configured horizontally or vertically. Due to their low speeds Lobe Pumps can be operated at between 20-1200rpm ensuring liquids are handled in a gentle slow-motion preventing their consistency from being changed. Our Lob pumps can handle liquid viscosity between 1cst and 55,000 cst, and produce flows up to 300M³H, while handling liquids up to 150°C. Rotary lobe pumps are useful for pumping and Transferring of highly viscous liquids like Butters, Chocolates, Fruit Pulps, Flavorings, Frostings, Fats & Oil, Yeast Slurry, Sugar Syrups, Creams, Meat Chunk, Soup, Sauce, Tooth paste, Resins, Jams, Jellies chocolate mixtures, Ice Cream, Essential oil, Shampoo, cheese, Face cream , Lotions, Baby Foods, Tomato ketchup, Fruit juice etc.

C-Way Engineering Exports offer a wide range of high quality Lobe Pumps which are designed for long life extended running. Our Lobes are available in single lobe, Bi lobe, Tri Lobe & Butterfly Type. Lobe Material is customized and available with Special coating if required according to customer application. We design pumps according to the customer requirements and application.
