What it is

The Ferroli 3980F220 is a central heating pump assembly built around a Grundfos UPS 15/50 circulator. It moves heated water around the primary circuit on Ferroli Optimax 25C and 25S boilers. The assembly supersedes part number 151654.

Signs this part needs replacing

  • Radiators stay cold while the boiler fires and reaches temperature, indicating no circulation.
  • The pump runs hot, or emits rumbling, grinding or whining noise from the pump head.
  • The boiler locks out or trips on overheat because flow through the primary circuit has stopped.
  • Water leaks from the pump body, gasket face or pipe connections.
  • The pump does not start when called, with no hum or vibration at the housing.

Before you order

  • Confirm the boiler model and product code on the data badge match the fitment list.
  • Check the existing pump for the UPS 15/50 marking.
  • Verify part number 3980F220 against the old component or the manufacturer's parts list.
  • Confirm the system is drained and isolated before removal.
