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

  • Suction branch

    flange connection according to DIN EN ISO 228-1 or NP

  • Pressure casing

    with drain plug and connections for pres- sure/vacuum gauge. Flange connections according to DIN EN ISO 228-1 or NPT, can be rotated in 90° increments.

  • Rotor

    wear resistant and corrosion proof materials, with additional surface treatment.

  • Stator

    flexible stator, fixed on one side.

  • Universal joint sleeve with holding bands

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

  • Joint connection

    consisting of just 5 components. Power transmission through wear resistant, hardened and replaceable joint parts, easily repaired.

  • Plug-in shaft

    connects the drive shaft to the joint.

  • Shaft sealing

    single-acting mechanical seal, located inside the pumped product.

  • Shaft sealing retainer

    for retaining the mechanical seal and for centering of the drive.

  • Drive

    electric motor, directly flanged to the pump without additional couplings or guards, upon request geared motor or variable speed drive available.
