Belzona Facts
After installation the operating parameters of the pump were excellent; the power consumption reduced by 10-12%, from 270-280 amp prior repair to 240-250 amp. The operating pressure increased from the previous 8-8.5 bar to 9-9.5 bar and the flow rate increased from 400 m³ to 450 m³. This means the repaired pumps performance  corresponds to the manufacturer’s original parameters.
