.......... in other words, maintained efficiency has always been, and will continue to be, a fundamentat virtue of all Warren Pumps. Original efficien cies in a pump can be very misleading and a source of ditappoiniment in its long range efficient life expectancy. The three most important factors affecting main tained efficiency are hydraulic design, leakage losses and friction losses. The generous acceptonce of Warren Pumps for well over half a century WARREN STEAM PUMP COMPANY^ WARREN, MASSACHUSETTS^ CENTRIFUGAL RECIPROCATING POWER HIGHJob at Temperatures For bolting applications involving high temperatures or high pressures, it pays to use the Bethlehem Con tinuous-Thread Stud, together with two Bethlehem Quenched Nuts. Thii.stud-and-nut combination is ideal for difficult bolting jobs because It resists the premature fatigue failure often induced by fluctuating temperatures and pressures. It's an economical combination, too, be cause of its ioog service Ufe. The Bethlehem Continuous-Thread Stud has no point of thread-runout. Therefore those stresses which could contribute to early failure are well distributed over the full working length of the stud, rather thao being allowed to gather at any one point. The Bethlehem Quenched Nut, made from .40 to .90 carbon steel, is formed by forging and extruding hot steel in a forming die. It is then quenched and tem pered, This procedure makes the nut sufficiently strong to break virtually 8ny stud or bolt on which it may be used. Like its companion stud, the Quenched Nut is furnished in a wide range of sizes. It wilt be well worth your while to consider Bethlehem Continuous-Thread Studs and Quenched Nuts for high-temperoture bolting. The nearest Beth lehem office, is at your service.
