How will a twin impeller pump change the feel of my shower water?

A twin impeller pump boosts your hot and cold supplies by the same amount, so your mixer or thermostatic shower gets a steady, equal flow instead of one side overpowering the other. You'll notice stronger, more consistent spray even if your incoming pressure is low; for a modest uplift look at 1.5 bar models like the CT50XTRA, while a 2.0 bar unit such as the RP75PT gives a noticeably firmer jet for a power shower.

Which bar rating should I pick, 1.5, 1.8 or 2.0?

Choose 1.5 bar for a small to medium boost suited to a single standard shower; 1.8 bar is a good middle ground if you want a bit more power without jumping to the top spec; and 2.0 bar gives the strongest small-to-medium increase, better for power showers or if you want stronger flow to more than one outlet. the CT50XTRA (1.5) suits a single family shower, while the CT75XTRA or RP75PT (2.0) will better support a larger shower head or simultaneous outlets.

What's the difference between regenerative and centrifugal pumps, and which should you choose?

Regenerative pumps generate higher pressure at moderate flow, so they're excellent for single showers where head is more important; options include CT50XTRA and CT75XTRA. Centrifugal pumps deliver higher flow at lower head, making them better when you need to feed several outlets at once; examples in the range are the RP models. If you mainly use one shower, a regenerative model is economical and effective; if you want to run a shower and basin together, a centrifugal option is more suitable.

Are brass pumps better than plastic ones for long-term use?

Brass components are generally tougher and more resistant to wear, so they tend to last longer in regular or heavy-use situations, whereas plastic constructions reduce cost and weight but can be less durable. There are four brass models and seven plastic ones in this selection, and you'll often see brass on the higher-priced, heavy-duty pumps in the the current product price band. If you use your pump frequently or want greater longevity, a brass-bodied model is worth the investment.

Can one of these twin pumps run a shower and a bath or multiple bathroom outlets at the same time?

Yes, but capacity depends on pump type and pressure rating: centrifugal pumps with higher flow are better for running a bath and shower together, while a high-pressure regenerative or a 2.0 bar unit can support multiple outlets up to a point. a centrifugal RP75PT or a 2.0 bar CTFORCE20TU will handle more simultaneous demand than a 1.5 bar regenerative CT50XTRA, which is best kept to a single shower.
