Spare parts

Spare parts & wear components

Original, replacement and compatible components for pumps that are already installed.

How a part gets identified

Send us a part number, drawing, nameplate or photo.

  1. 01

    Part number or drawing

    The fastest path. A part number, sectional drawing or parts list is usually enough.

  2. 02

    Pump nameplate

    Manufacturer, model and serial number let us work back to the parts list.

  3. 03

    Photo and measurements

    Where no documentation exists, a clear photo with key dimensions is a workable starting point.

Spare parts

Keep the installation.Replace what wears.

A worn rotor set or a failed seal does not require a new installation. In most cases the wear parts can be replaced within the existing pump.

  • 01

    Mechanical seals

    Cartridge and component seals, with face and elastomer options.

  • 02

    Screw sets

    Matched power and idler rotor sets for screw pumps.

  • 03

    Rotors

    Rotors and impellers, including coated and hardened variants.

  • 04

    Stators

    Elastomer stators for progressing cavity pumps.

  • 05

    Pump liners

    Casing liners and bushings that define internal clearances.

  • 06

    Bearings

    Rolling and sleeve bearings with the matching retaining parts.

  • 07

    Gaskets

    Flange, cover and casing gaskets in application-suited materials.

  • 08

    O-rings

    Elastomer sets selected for fluid and temperature compatibility.

  • 09

    Couplings

    Flexible couplings, elements and coupling guards.

  • 10

    Pump internals

    Shafts, sleeves, wear plates, balance pistons and fasteners.

Good to know

01Wear parts are often available faster than a complete pump.

02Seal faces and elastomers must match fluid and temperature, not only dimensions.

03Rotor sets are matched components — they are replaced as a set.

04Compatible parts are offered as compatible, never as manufacturer-branded items.

Final pump selection is always confirmed technically before an order is released.
