ELIMINATE MAINTENANCE PROBLi with Ingersoll-Rand PUMPS Now available for general hydraulic service\ heads to 300 ft.--capacities to 1900 gpm NO STUFFING BOX ATTENTION There ere no packed stuffing boxes in the new DM& pumps. No periodic adjustment--no repacking--no annoy?! ing teaks. Double Mechanical Shaft Seals are itandefi' equipment with water pumps. These performance-proved mechanical seals are self-adjusting-require no attention' for the entire service life of their sealing faces. Replo&vj ment, when needed, is greatly simplified by easily acco-'1 sible seal-box extensions. Double seats give better pumpi>! performance under suction lift, too--and last longer bn* gritty-liquid service. ^ NO BEARING LUBRICATION Greasing or oiling of pump bearings is a thing of the pastil The DMV uses modem, cartridge-type ball bearing! wit# the lubricant permanency seated in. Seated bearings of^ this same type have operated successfully ond without^ attention for periods of more than 11 years in tough service! FOR PAPER PRODUCTION When Great Northern Paper Company needed more power for its operations in northern Maine, Stone & Webster Engineering Corporation was called on for consultation and recommendations. The Corporation prepared a report, and subsequently designed and built the Ripogenus hydroelectric project on the upper Penobscot River. Water from a storage dam is brought downstream through a solid rock tunnel for 4000 feet to McKay Station. The transmission line connection to the Millinocket plaVt and the required road work and bridges were engineered and constructed by Great Northern's own forces. Now you can put an end to the care ond nursing of out' dated pumps. The DMV line gives you o pump that con' be installed anywhere with complete confidence. Moin% tenance requirements are practically rero. And the simpleaccessible design saves on spare parts inventory-cu** costly down-time.
