ROTH REGENERATIVE TURBINE DESIGN LICKS LOW NPSH PROBLEMS! ROTH Turbine Low NPSH Pumps derive their extremely low minimum NPSH characteristics from the low disturbance at suction which gives way to a gradual pressure build-up throughout the pumping cycle. These pumps employ a booster stage of patented exclusive ROTH design to provide a surplus of pressure over vapor pressure at the suction of the turbine adequate to its minimum NPSH requirements . . . Available in either single-stage, end-mounted, end-suction design with separate power frame (for heads to 900 ft. TDH), or 2-stage, center-mounted, vertical suction design (for heads to 1400 ft. TDH). Equipped with ASA flanged connections, John Crane or Dura Seals, and extra heavy ball bearings. RANGE Head: 150 to 1400 f t . Differential: 50-600 PSI Cap: 2 to 100 GPM

Midget Iron Tester Gives Fast, Accurate Tests of Iron in Water or Brine Here's a c o m p a c t , l i g h t w e i g h t tester t h a t lets you make on-thespot tests for iron content in water or brine in a matter of minutes. Gives completely accurate data to help control corrosion in piping, valves or condenser systems . . . helps you prevent scale formations in steam boilers or iron oxide deposits on heat exchanger surfaces. Sealed-in-plastic color standards cover the 0-10 ppm range which can be extended by diluting the sample. Tests are made simply by placing treated sample in test tube and comparing color with standards.

Tank Covers Tank covers for handling strong, hot acid solutions are made of Duracor, a reinforced plastic which

TAYLOR

Two patching cements are available. Vicel is a solvent type that dries by evaporation, leaving a tough film or acrylonitrile—vinyl chloride copolymer. Nycel is a two-component epoxy cement formulated to give exceptional strength, fast curing time, and excellent resistance to acids, alkalies, and solvents. Dept. IEC, Technical Fabricators, Inc., 136 Washington Ave., Nutley, N. J. 23
