What it is
The Grundfos MAGNA1 50-120F is a single head variable speed circulator designed for circulating heating and domestic hot water in closed systems. It is an 'A' rated, EuP ready pump operating on a 240V single phase 50Hz supply. The MAGNA1 range uses integrated speed control to match output to system demand rather than running at a fixed duty.
Signs this part needs replacing
- The pump runs but circulates poorly, with radiators slow to heat or uneven temperatures across the system
- Abnormal noise, grinding or vibration from the pump body during operation
- The pump stops running entirely or fails to start when demand is present
- Repeated fault indication or loss of speed control on the pump display
- Visible leakage from the pump housing, flange joints or seals
Before you order
- Confirm the model designation on the existing pump matches 50-120F
- Check the electrical supply is 240V single phase 50Hz
- Verify the system pressure class and flange connection against PN6/10 and the 280 reference
- Confirm the pump is a single head variable speed unit, as the MAGNA1 range includes other configurations
