What it is

The ATAG UPS 20-50 Pump is a circulation pump assembly supplied under part number 86124100. It is the pump set used to move heating water around the primary circuit of the ATAG appliances listed below. The UPS 20-50 designation is the pump type referenced against this part number in the ATAG spare parts listing.

Signs this part needs replacing

  • The pump runs but the appliance reports a low or no flow fault.
  • The pump body is noisy in operation, with rumbling or scraping from the impeller area.
  • The pump fails to start, or the shaft cannot be turned.
  • Water is weeping from the pump body or its seals.
  • Heating output is poor or uneven across the radiators because circulation has dropped.

Before you order

  • Confirm the appliance model against the fits list, as the same part number is listed for several ATAG models.
  • Read the part number off the existing pump or the appliance data badge and match it to 86124100.
  • Check whether the fault is at the pump or in the external wiring and controls before removing the pump head.
  • Isolate the electrical supply and shut off the water before starting work.
