TridentDigital Display Heating Circulation Pump.

Excellent pump!!

I needed a pump urgently so went for this one. It's noisy the system now viabrats in every room. Would not recommend unless it is very far away.

This is the forth pump I’ve replaced in our central heating system, so I’m quite familiar with the fitting process. Both joints either side leaked, when the system was refilled, this thankfully didn’t damage the ceiling below, but caused the loss of the expensive inhibitor fluid, as the system had to be drained to attempt a refit. I guess the seals are on the thin/narrow side, in the end the pump was tightened with all my strength and the seals eventually did their job. Job done I thought… oh no, it’s very loud (sounds like a starter flywheel on a T6 aircraft)! It’s far too loud and annoying for us, I’m now looking for a replacement (another customer has made the same complaint). I made the purchase because the ceramic impeller and shaft sounded resilient in the specifications, it may be, but I’ll never find this out.

Instructions difficult to read as print very small,also found difficult to understand would have been better with words instead of pictorial information!
