Stuart Turner Showermate EPDM PTFE Aluminium Oxide Seals

EPDM/PTFE/Aluminium Oxide Seals

PTFE and Aluminium Oxide seal materials provide the most reliable sealing solution available, reducing risk of pump leakage and resulting water damage to the home while the use of PTFE (Teflon) also reduces the chances of the seal sticking when a pump is not used for periods of time.

Stuart Turner Showermate Continuously Rated Motor

Continuously Rated Motor

Continuously rated shower pumps effectively run until the user turns it off. This is particularly good in a family home where the shower needs to be used frequently throughout the morning or evening. A pump that isn’t continuously rated will turn itself off to allow the pump to cool, potentially causing issues with water pressure to the shower.

Twin Impeller Shower Pump

Twin pumps are designed using the highest standard of technology to boost your water pressure of both hot and cold water supply to a single shower, bath, shower mixer or mixer tap. Put a stop to low water pressure with this pump. It is perfect for transforming your unsatisfactory shower into a powerful and invigorating shower that you'll never want to leave.

Positive Head

A positive head shower pump is designed to be gravity fed, therefore it needs a 'head' of distance (at least a metre) between the pump and the bottom of the cold water cistern. The gravity feed 'kick-starts' the pump, pushing water straight through to your shower.

Stuart Turner Showermate Dry Run Protection


Dry Run Protection

Dry run protection is really important for the wellbeing of your shower pump. Bearings and other internal parts may get seriously damaged if there is a blockage or a drop in pressure causing the pump to run dry.

Stuart Turner Showermate Flow Switch Sensitivity


Flow Switch Sensitivity

An automatic flow switch is crucial to have the shower running when it needs to be. When flow exceeds 0.8 litres per minute the pump automatically starts, delivering that powerful flow that it’s there for.

    This was worth buying and can feel the difference, this replaced the 3 bar monsoon pump that just didn't give you the wake up feeling, like the 4.5 bar does. Even though longer in body size I didn't need to alter any of the pipework, and it is quieter than my older Bristan 3b pump. I ordered it Friday morning and was delivered Sat 8.30am at no extra cost, so I fitted it straight away to test. Brilliant, Definitely recommend it.

    Quality pump that has more than enough power to have 2 strong power showers running at the same time. Replacing an earlier Stuart Turner pump that worked hard for us for about 13years. Very happy to recommend

    Had the same pump but lower power for 10 years but developed a fault. Wanted a bit more power, this delivers it beautifully! However, beware, it empties your hot water tank more quickly!
