Lobe Pumps - idexindia
  • Lobe Pumps

    Lobe pumps are majorly used in hygienic and sanitary applications in a variety of industries that include Pharmaceuticals, Biotechnology, Food, Beverages, Dairy, Personal Care and Chemical. They offer high efficiency, low shearing, excellent clean-in-place and sterilize-in-place (CIP/SIP) characteristics, making them a popular choice in their domain. They provide almost constant flow and if wetted, have self-priming capabilities.

    Some of the basic requirements for hygienic or sanitary pump are:

    • The wetted/contact parts should be easily accessible for cleaning
    • There should be minimum construction material (preferably Stainless Steel & FDA (or food grade) Elastomer)
    • There should be no metal for metal-contact
    • The pumping chamber should be free from any crevices, pits etc.,
    • Surface finish should be <= 0.8 um
    • Certifications should include 3A and or EHEDG

    Operating Principle of Lobe Pump:
    • During operation, as the lobes come out of mesh, they create an expanding volume on the inlet side of the pump. Liquid flows into this cavity and is trapped by the lobes as they rotate.
    • As the lobes continue to rotate, liquid trapped within the cavity between the lobes gets transported to the discharge side of the pump, without passing between the lobes.
    • The converging lobes displace fluid into the discharge port, creating a pressure differential across the pump head.

    The lobe pumps offer low-shear action and straight-through flow. This ensures high quality and enables the pumps to handle a wide range of fluid viscosities, while maintaining the accuracy. At IDEX, we understand the importance of hygiene standards and delicate product handlings required in these industries, and therefore provide the best.
