Positive and negative head shower booster pump
Our STR2 and SSR2 Universal pump range enhances the water pressure in a bathroom or single shower. These high performance shower pumps improve the efficiency of the water flow to a household bathroom. Suited to a gravity fed system where the water outlets are above or the same height as the cold water tank.
Having a dual function of a positive and negative head makes our shower pump suitable for most residential households. Designed to be extremely low noise with a quiet induction motor and a pump head with minimal vibration.
All models in our STR2 and SSR2 universal range are fitted with 22mm stainless steel hoses, high quality long-life seals and have IPX2 water ingress protection.
In addition, our innovative design has dry run protection and the pump automatically switches on when the outlet is opened and regenerative impeller eliminates air pockets that are occasionally formed in a shower system. Making our shower booster pump range reliable, resilient and robust.
Enhancing the water pressure to the bathroom with a Grundfos shower pump can drastically improve the shower experience allowing your customers to upgrade their shower without replacing it. This pump range is cost effective, easy to install and WRAS approved.
