Seal & Spacer Kits

Trebles supplies seal and spacer kits for circulator pump replacements, helping overcome differences in port-to-port dimensions when upgrading or replacing older pumps. Popular kits for manufacturers including Grundfos, Lowara and Wilo are held in stock at our warehouse for speedy delivery.

Compatible with Pump Replacements

Spacer kits help accommodate dimensional differences when a newer pump has a shorter body than the model it replaces.

Ready to Install

Kits typically include the spacer, extended bolts, nuts and gaskets required to complete the installation.

Cost-Effective Alternative

A spacer and seal kit can avoid unnecessary pipework alterations or the replacement of otherwise suitable system components.

Changes to circulator pump dimensions can create a problem when replacing an older pump, particularly where the new model has a different port-to-port length. This is common when upgrading systems or replacing discontinued pump models with newer equivalents.

A spacer kit fills the difference between the existing pipe connections and the replacement pump, allowing the new pump to be installed without altering the surrounding pipework in suitable applications.

Kits generally include a spacer, extended fixing bolts and matching nuts, together with the required gaskets. Not every replacement pump is supplied with a spacer kit, so it is important to check what is included with the pump before ordering.

Trebles stocks popular seal and spacer kits for manufacturers including Grundfos, Lowara and Wilo. If you are not sure which kit is required for your pump replacement, our team can help identify the correct kit.
