May, 1925 MARINE REVI Ww 25 Worthington Volute Condenser Circulating Pump The Circulating Water PERATING efficiency, aboard ship, might almost be said to be primarily a matter of efficient water circulation; condenser circulation in a steamer, jacket and piston cooling water circulation in a motorship; sanitary circulation; fresh-water circulation. A sure, efficient and reliable means of promoting this circulation for any of these purposes, is a WORTHINGTON centrifugal pump. Many years of engineering experi- ence have demonstrated the high efficiency of the centrifugal pump for moving large volumes of water, and WORTHINGTON centrifugals are eae in accor- dance with the best approved principles of the art. And in emergencies—for fire duty, or for freeing the ship of large masses of water after collision or grounding —the demonstrated entire reliability of WORTHINGTON equipment makes it a strong staff upon which to lean.
