The shower pump rotates the blade and propels the water to shower head. Shower Pumps are of two types, positive head or negative head. Apart from positive and negative heads shower pumps also differ in impellers, which are known as single and double impellers. Below we have listed a complete series of negative & positive head pumps, with both single and double impeller options. We stock pumps from brands such as Salamander, Sagittarius, Stuart Turner and Techflow. Negative Head Pumps are used in situations when the pipework from the pump runs through the loft, and the distance is less than two feet. Feel free to browse our web store and select the right one based on your requirement.
