What it is

The Riello pump seal 3020443 is a sealing component for the oil pump fitted to Riello R40 series burners. It seals the pump shaft against the pump body, preventing oil leakage and stopping air from being drawn into the oil supply. It is a service part for Riello burner spares used on boiler and burner assemblies.

Signs this part needs replacing

  • Oil weeping or a damp oil film around the pump shaft or pump body
  • Oil residue collecting beneath the burner or on the appliance casing
  • Air being drawn past the seal, causing unstable combustion or a rough flame
  • Repeated burner lockouts or ignition faults traced to the oil pump
  • Pump unable to hold vacuum or pressure during a combustion check

Before you order

  • Confirm the burner model code and type against the fitment list above
  • Identify the pump fitted to the burner and check the seal location and seating
  • Inspect the pump shaft and body for scoring or wear, as a worn shaft will damage a new seal
  • Check the oil supply line and filter condition so the new seal is not contaminated on start-up
