Salamander Single Impeller Pumps - Over 2.0 Bar

The bar rating is the size of the pressure boost the pump will add to your supply, higher numbers give a stronger boost. Models here range from 2.4 (Salamander RP80SU) and 2.5 (CT85XTRA) up to 3.0 (CT Force 30) and 3.6 (RP120SU); a 2.4–2.5 bar pump will noticeably improve a single shower, while 3.0–3.6 bar is better if you want a powerful, spa‑like spray or need more force when water is very weak. Bear in mind these are single impeller pumps that boost one supply (hot or cold). If you want a lively mixer shower or stronger spray for body jets, aim for a 3.0 bar or above.

No, a single impeller pump boosts one supply only, either hot or cold. If both sides are weak you would need a twin impeller pump or separate pumps to boost both simultaneously. For many homes where only the cold or hot is underpowered, a single impeller (like the CT85XTRA or RP80SU) is a simpler, lower‑cost solution.

Regenerative pumps typically produce higher pressure at lower flow, making them ideal for a single shower outlet; centrifugal pumps deliver higher flow and are better when you might run several outlets together. a regenerative 2.5 bar CT85XTRA is a strong, budget‑friendly choice for one powerful shower, whereas the 3.6 bar centrifugal RP120SU is a good option if you need more flow for a bath and shower used at the same time.

Brass bodies are tougher and resist corrosion and heat better, so they tend to last longer in demanding conditions or hard water areas. Plastic models (three included in our range) are lighter and usually cheaper, the CT85XTRA is an example of good value, and are fine for less intensive use. If you use your shower frequently or want the longest service life, brass is worth the investment; for occasional use, a quality plastic model will do the job.

The Salamander CT85XTRA at the current product price is the most budget-friendly option in this range and offers a 2.5 bar regenerative boost, so you get a strong improvement without a high price. The trade-off is a lower maximum bar than the 3.0–3.6 models and typically plastic construction, but it is well suited to a single shower where you want good performance for less money. If you need a noticeably stronger spray or higher flow, stepping up to the 3.0 or 3.6 bar models will cost more but deliver the extra power.
