The new AhlstarUP pump offers high efficiency over
a wide operating range. |
Pumping requirements are one of the major electricity consumers in the process industry. Carbon dioxide emissions can be reduced by increasing the efficiency of process pumps. As the total electrical power demand of Sulzer pumps operating in the pulp and paper industry exceeds 7000 MW, the upgrading of installed units with new high-efficiency pumps is a possibility to reduce energy consumption notably. Sulzer Pumps has studied the life-cycle costs during the average 20 years of operation for pump applications in a typical modern pulp mill, where the new AhlstarUP product line was compared with the existing Ahlstar™ series. The study showed life-cycle savings in energy costs of EUR 4.4 Mio and in CO2 emissions of 124,000 tons. |
