Actual comparative tests under laboratory conditions confirm that Stuart Turner manufactures the quietest peripheral (regenerative) shower pump available.
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.
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 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.
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.
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.
Brass Construction
Built to perfection, this shower pump features durable and robust brass construction. This ensures that your shower pump is running as smoothly as possible, even after many years of use, making you a very happy customer indeed.

WRAS Approved for quality
If you’re buying any sort of water fitting or product then it’s important that its WRAS (Water Regulations Advisory Scheme) approved. It’s the best way to work out if that particular product or part complies with the UK requirements for installation within the UK.
Flexible hoses included
This shower pump comes complete with four flexible hoses, which are used to link your shower pump to both incoming and outgoing water pipes. These flexible hoses are anti-vibration which means the hoses are less prone to vibration from the pump, helping to reduce noise and prevent damage to the pump itself.

I decided to bite the bullet and pay the money. I use the ST 4.0 to power two showers and it doesn't disappoint. It is still noisy however not as loud as my previous pumps. I guess you're never going to get a completely quiet pump. The power is great even when using both showers. This uses 22mm flexi hoses so may have to do a little plumping as most households have the copper ends reduced to 15mm. Overall happy and got it at a good price from plumb world.

I bought this to replace an old shower pump that no longer worked.
Plumbworld had this 4.0 bar pump in stock and at a very good price.
Delivery was very quick - I could have had it the following business day if I'd wanted. This is a powerful and quiet pump and well worth the price

Pump arrived within a day and on time. Price was way better than anywhere else - my local bathroom supplier quoted me almost twice as much as Plumbworld for exactly the same item. Quality of pump first rate.

Good price. replacing identical pump. New one slightly smaller footprint
Also, sounds quieter, but this may be partly the insulating base - optional extra.
