Wobble Pump

W Wobble Pump


SEEPEX wobble-stator pumps work reliably in many industries. They efficiently transfer liquids of thin to moderate viscosities, even with a high solids content. In contrast to conventional progressive cavity pumps they have a rotating unit with only one joint, which is why the stator “wobbles.”

Properties & Benefits
  • High product safety: stator material and secondary seals are FDA approved (Food and Drug Administration, USA)
  • CIP (Clean In Place) with high velocity flow in the suction casing
  • US 3-A Sanitary Standards and EHEDG compliance
  • Particularly easy to maintain due to easy-to-assemble joints along with the plug-in connection between the rotating unit and drive
  • No special tools needed for assembly/disassembly
  • Optimized, dead-space-free pump casing prevents product build-up
  • High-quality casing surfaces and the rotating internal parts ensure residue-free cleaning
  • Multiple mechanical seal options ensure hygienic shaft sealing
  • SIP (Sterilization In Place) with superheated steam

  • Connections

    Connections according to DIN EN ISO 228-1 or NPT.

  • Main Housing

    With drain plug and connections for pressure instruments, either in cast grey iron or stainless steel.

  • Rotor

    Wear and corrosion resistant materials, with hard coating as standard.

  • Stator

    Flexible stator, fixed on one side, with a reinforced flexing area that lasts longer than other designs. Special care has been taken to enhance the mechanical efficiency to lower both the starting and running torque.

  • Universal Joint

    Consists of just five components. Power transmission through wear resistant, hardened and replaceable joint parts: easily repaired.


    Protects the grease-filled joints from penetration of the pumped product, even in case of maximum pressure loading.

  • Plug-In Shaft

    Connects the joint and drive.


    Single-acting mechanical seal, located on the pressure side to minimize the NPSHr and ensure positive sealing with an unbalanced seal.


    For retaining the mechanical seal and centering the drive.

  • Drive

    Electric motor, directly flanged to the pump without additional couplings or guards. Gearmotors and electronic or mechanical variable speed drives are also available.
