PUMP PRESSURE RATING

 

Shower pump performance is measured in bars (water pressure). 1 bar of water pressure equates to 10 metres static head of water. The higher the bar rating, the higher the performance and efficiency of the shower pump.

​

Here is a general guide to bar ratings and their relations to performance levels:

• 1 bar rating = low boost performance

• 1.5-2 bar rating = medium boost performance

• 3+ bar rating = high boost performance

NEGATIVE TWIN HEAD PUMP

 

DDV recommend Stuart Turner Pumps for shower pump replacements and installations because of their strength and overall efficiency. Stuart Turner Negative Pumps are designed with twin heads, which allow them to boost both hot and cold water supplies, as well as presurise water in areas below the water source (an example would be a bathroom in a converted attic). These pumps can be installed in open vented hot or cold water systems, and they are fully automatic – meaning they do not require gravity flow of water to start. If your building has a positive natural flow, a negative twin head will pressurize the entire system and distribute strong water flow throughout all of your rooms.
