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.
Where the water level in the cold storage tank is below the level of the shower outlet a negative head situation exists. Specialist Automatic Negative Head pumps to overcome this problem are available from Grundfos.
The Brass Pump range is undoubtedly the Rolls Royce of Grundfos shower pumps, designed and manufactured to the highest of standards. With brass impellers and machined brass stampings these pumps can be genuinely described as Heavy Duty, and each model offers high performance and durability. These continuously rated regenerative pumps are suited to domestic, commercial or light industrial use. Products within this range are fitted with long-life silicon carbide seals and anti-vibration feet keep the operating noise to a minimum. All brass pumps are supplied with stainless steel flexible hoses, and are covered by a comprehensive 5 years warranty. A brass pump will transform any compatible shower system into a really enjoyable and invigorating power shower.
The installation of a Surrey flange is recommended for pumps up to 3 bar pressure.

Needed to replace pump, only 2 1/2 years old with, I suspect, a U/S PCB. Expensive kit to fail after only 2 1/2 years but Grundfoss will apparently service items less than 5 years old. Yet to see how good that service is. As far as PlumbWorld is concerned, they provided great delivery at the best price on the Net.

Cannot believe I am excited by a pump but I am. This is a real beast with incredible power yet surprisingly quiet. Great price and excellent service from Plumbworld. Tour De force with my new
Mira Agile Sense ERD+ also from Plumbworld. Thanks.

We wanted a new pump to operate our steam cabinet. The Grundfos pump was a good price for a negative head pump and it works beautifully. It arrived quickly and was well packaged. Fitting it was easy and we can now enjoy a steam!!
