This question is regarding 4.0 Bar Negative Twin Impeller Amazon Brass Negative Head Heavy Duty Regenerative Shower Pump

Replacement pump?

I have a Trevi 45 twin 3.5 bar pump that is inadequate for our two showers. Would this one be a suitable replacement? Considering the 4 connectors are all on the one side.

Yes the Grundfos would certainly do the job.

However if this is your Pump below then it will not be 3.5 bar.

Stuart Turner made it for various manufacturers It came in various versions from approximately 1.5bar to 2bar if you can send us a photo of the plate on top of the pump and a photo of the pump then I will be able to tell you which version you have.

The pump you have is a regenerative pump (Regardless of it's output) You may want to consider a centrifugal pump at the same pressure they will deliver a better flow (Handy for two showers) However the installation instructions are slightly more onerous.

The oves you need to look at are at the foot of page one and top of page two.

This is a 1.5bar pump approximately 17 years old
The 3.5bar you see on the plate is the maxim um pressure that the pump can take.

Assuming you have had no problems with your existing pump I would fit the pumps below.
