What it is

The Riello 20033550 is an oil pump supplied for Riello RL38 and RL50 burners. It replaces the earlier part number 3003998 and carries the reference ALV95 C9427. The pump delivers oil at pressure to the burner nozzle, forming the core of the fuel supply side of the combustion circuit.

Signs this part needs replacing

  • Burner fails to establish or hold a stable flame despite a healthy oil supply
  • Pump pressure cannot be set or held at the required level on the pressure gauge
  • Oil leaking from the pump body, shaft seal or union joints
  • Noisy pump operation, including grinding or rattling under load
  • Burner locking out repeatedly with fuel-related fault codes

Before you order

  • Confirm the burner model is an RL38 or RL50 before ordering
  • Check the existing pump part number against 20033550 or the superseded 3003998
  • Inspect the pump coupling, shaft and oil line connections for wear or damage
  • Verify the nozzle and filter condition so a new pump is not masking another fault
