Negative head shower pumps are designed for homes where the outlet you wish to pump to is higher than the cold water storage tank. A perfect example would be if you have converted part of the loft into a spare bedroom with an ensuite and the shower head is above the outlet on the storage tank which is also usually stored in the loft. Our range of Negative Head Shower Pumps (Twin Impeller) have been separated out into over and up to 2.0 bar to make it easy for you to find what you need. Up To 2.0 bar will be a low to medium boost while anything over 2.0 bar will be a larger boost.
