My Amfa domestic water pump was leaking.
I removed the pump and found that the circlip that holds the pumps shaft seal was broken and worked its way into the side of the seal. I removed the seal and found it also had a small chip in it.
I ordered the metric seal from a local supplier and also the circlip from McMaster.
Being that I had a complete spare pump I installed it.
The pump would not pump water. I added water in the output side of the pump and it flooded the bronze impeller.
I was quire frustrated.
I assumed there was something wrong with the new pumps impeller. I took it apart, everything was 100%.
I was working on the saloon table and had the old pump next to the new one. Luckily I noticed that the Square D switch was wired backwards from the new switch. Thus the pump was running backwards. I switched the wires and Voila- Water.
Possibly this might help someone installing a new amfa pump.
