Grundfos Amazon Pump 2.0 Bar Negative Head Pump

Where the water level in the cold storage tank is below the level of the shower outlet, a ‘negative head’ situation exists.

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 for 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 2 years warranty.

A brass pump will transform any compatible shower system into a really enjoyable and invigorating power shower. The installation of a Grundfos Surrey flange is recommended for pumps up to 3 bar pressure.

Surrey flanges available - designed to provide an independent hot water supply, reduce air surging noise and temperature variations.  Please select in Additional Extras if required.
