Standard Pump

N Standard Pump

The Basis

Product group N pumps are the basis for SEEPEX progressive cavity pumps. They are used in almost all industrial sectors and convey low to highly viscous media with or without solids. Those benefits along with others ensure the pump’s economical operation.

  • Pressure branch

    connection for pressure/vacuum gauge. Flange connections in DIN or ANSI.

  • Rotor with 6L Geometry

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

  • Stator with 6L Geometry

    the seal on both ends is moulded as an integral part of the elastomeric stator; corrosion of the stator tube is never a problem because the pumped liquid never comes into contact with the metal tube or the bonding adhesive. Available with optional adjustable stator retensioning device.

  • Tie Bolts/Screws

    corrosion proof, optional available in stainless steel design.

  • Coupling Rod

    for power transmission. Improved design, special designs optional available.

  • Suction Casing

    with large cross section and designed for smooth flow conditions, with drain plug and connections for pressure/vacuum gauge. Flange connections in DIN or ANSI can be rotated in 90° increments.

  • Joint Connection

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

  • Universal Joint Sleeve with Holding Bands

    protects the grease-filled joints from penetration of the liquid pumped, even in case of maximum vacuum or pressure loading; streamlined design to reduce turbulence and NPSHr.

  • Shaft Sealing

    gland packing with or without flushing/seal cage ring or single or double mechanical seals.

  • Plug-In Shaft

    connects the drive shaft to the joint; with gland packing the plug-in shaft is used as a shaft protection sleeve; upon request, it is available with wear resistant coating.

  • Plug-In Shaft Connection

    for easy dismantling of the pump and drive enabling quick replacement of the rotating parts and shaft seals. The plug-in shaft pin secures the shaft connection to the drive and the splash ring protects the bearing from contamination/gland leakage.

  • Lantern

    for connection of pump and drive and to secure the assembly to the baseplate or directly to the foundation.

  • Drive geared

    geared motors, variable speed drives or hydraulic motors of all major manufacturers, directly flanged to the pump without additional couplings or guards.
