What's Included

• Grundfos Amazon Twin Impeller Positive Head Brass Pump 4.0 Bar - STP4.0B

Are you tired of experiencing poor water pressure whilst showering? If so, you need to get your hands on a Grundfos Amazon Twin Impeller Positive Head Brass Pump. This clever pump will boost your water pressure to give you a powerful and invigorating shower every single time. Suited for domestic, commercial or light industrial use to boost shower pressure from 4 bar.

Perfect Water Pressure

Instead of purchasing a brand-new shower if your water pressure is a little low, we suggest you purchase a Grundfos shower pump. This shower pump will help to deliver the perfect water pressure to your shower.

Brass Construction

Built to perfection, this shower pump features durable and robust brass construction. This ensures that your shower pump runs as smoothly as possible, even after many years of use, making you a very happy customer indeed.

Twin Impeller

If you find that your shower is only delivering a small dribble of water when being turned on, then you need a twin impeller shower pump (hot & cold). This shower pump is designed to supply both hot and cold water to your shower for a powerful shower every single time.

Positive Head

Positive head shower pumps are for gravity-fed systems only. As a rule, if your cold-water tank is above the shower (maybe you have a shower in a converted room downstairs) and you have a flow rate as low as 0.5 bar, then you'll need a positive head shower pump.

Easy Installation

Grundfos shower pumps are incredibly easy to install — this is something we’re sure you’re happy to hear, as no one has copious amounts of time to spend trying to install a shower pump. We have included everything you will need for easy installation, meaning you can get your shower pump up and running in just a short amount of time.

WRAS-Approved for Quality

If you’re buying any sort of water fitting or product, then it’s important that it's 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.
