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, therefor 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.

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.

The Monsoon Standard 1.5 bar twin impeller shower pump is manufactured using the very latest techniques. This product can help to improve your hot and cold water supplies to your bath, shower, mixer or tap. Please note that this pump is only suitable for positive head applications. Standard pumps are controlled by a super effective flow switch, which automatically starts when a gravity flow (greater than 0.6-1.0 litres per min) through the outlet is detected. The pump will instantly stop when the outlet cancelled i.e when you turn off the shower.

Suitable for household use, Monsoon standard pumps are best suited for installation into open vented hot and cold water systems.

    5/ 5

    A shower pump designed and made (in the UK!) to last. Quiet, efficient and reliable and certainly worth paying the bit extra for - and helped with Plumbworld’s keen prices ...My plumber knows everything there is to know about shower pumps and he recommends Stuart Turner Monsoon absolutely!

    5/ 5

    We needed at quiet pump as it is located in the airing cupboard in a bedroom. Fitted mounted on a paving slap and anti-vibration mount, it is virtually inaudible. You need to open the door to hear it running. A brilliant bit of engineering and made in England!

  • Simon
    5/ 5

    Ordered the pump on a Tuesday and delivered on a Friday. Works well and much quieter than the Salamander pump we had before and it will hopefully last longer than the Salamander. It has a 5yr warranty so it should do.

    This was to replace a 20 year old twin impeller 1.5 bar pump. I found the performance not sufficient ( inadequate water pressure at the shower head ) Spoke to Stuart Turner and Plumbworld and returned this pump and purchased a similar 3 bar ST pump. Slightly more money but significantly more performance! This one passed the wife test. Great customer service from Plumbworld and Stuart Turner
