Grundfos Replacement Cartridge Assembly for Circulator Pumps

The Grundfos Replacement Cartridge Assembly is a service part for Grundfos circulator pumps, also called circulating pumps or hot water circulators. It lets you restore pump performance by replacing the worn internal pump assembly. You don't have to replace the whole pump.

Key Features:

• Replaces the internal cartridge (pump head) assembly of a Grundfos circulator pump
• Built to Grundfos specifications for reliable, quiet operation in closed-loop hydronic heating systems
• Lets you service the pump without removing the pump volute from the piping, which keeps downtime and labor low
• Available in several versions, each matched to specific Grundfos circulator pump models

Grundfos is a well-known name in pump technology. Fitting a genuine replacement cartridge helps extend the life of your circulator and keeps your heating system circulating efficiently. Choose the version that matches your pump model.
