Beargs are Sealed for Life. MECHANICAL SEAL All Series 497 pumps are furnished with a positive drive mechanical seal. The seal is a simple, selfadjustg, non-leak method of shaft sealg. It is especially suited for handlg liquids such as alcohols, solvents, etc. PUMPING ELEMENTS Internal pumpg gears are constructed of type 6 and type 770 Staless alloy. This allows high speed, non-gallg operation, handlg all types of liquids up to 25,000 SSU (5,500 cst). PPS composite idlers are also available for th liquid applications. INTEGRAL RELIEF VALVE Permits bypassg of liquid from discharge to suction side of pump. Prevents build up of pressure discharge le. GG, HJ and HL size valve mounts on pump head. AS, AK and AL size valve mounts on pump casg. 2 GPM (m³/hr ) (Nomal Ratg) Vikg s heavy-duty Series 497 pumps are available capacities of 0,, 0, 5, 50 and 75 GPM. All are built for high-speed handlg of th liquids requirg staless steel construction. These pumps are ideal for such liquids as solvents, alcohols and similar liquids. The three smaller size pumps can be furnished directly connected to either or RPM motors. The three larger sizes are directly connected to RPM motors. (See Series 497D units shown on page 64..) All six sizes of Vikg Series 497 pumps are furnished with sgle mechanical seals. This seal is a simple self-adjustg, non-leak method of shaft sealg located ahead of the casg ball bearg. The Series 497 pumps are built for con tuous or termittent duty for such applications as filterg, circulatg, transferrg or booster service chemical, general dustrial, petroleum and petrochemical uses. See followg pages or consult factory for specific recommendations. 2 Nomal capacities based on handlg th liquids at RPM on three small sizes, RPM on three large sizes. Solvents, alcohols, aqueous solutions and similar liquids. Metric conversions are based on US measurements and rounded to the nearest whole number.

DIRECT DRIVE UNITS ( D DRIVE) s with D Drive GG, HJ and HL Sizes s with D Drive AS, AK and AL Sizes Vikg s Series 497D units the GG, HJ and HL size (nomi nal ratg 0,, 0 GPM) are designed for high-speed, heavy-duty service. The pump is connected by a flexible couplg with guard directly to a or RPM motor. Both pump and motor mount on a sturdy formed steel base. Vikg s three large size Series 497D direct-connected units all feature the Series 497 high-speed pump connected by a flexi ble couplg with guard to RPM motor. Both pump and motor are mounted on a formed steel base. These make very compact, rugged units for heavy-duty service, handlg many types of liquids up to 25,000 SSU (5,500 cst).

6 Section 64 Page 64.6 VIKING HEAVY DUTY PUMPS Performance Curve Notes Prted performance curves are not available. Performance curves can be electronically generated with the Vikg Selector Program. This program can be located on INLET CONDITIONS: The performance curves show Based on 0 (or 5) In.-Hg. which is Vikg s standard test condition. This is not the maximum vacuum capability of the pump. NPSH (Net Positive Suction Head): The NPSH R (Net Positive Suction Head Required by the pump) is given the table below and applies for viscosities through 750 SSU. NPSH A (Net Positive Suction Head Available the system) must be greater than the NPSH R. NPSH R FEET OF LIQUID (SP. GR..0), Viscosities to 750 SSU Speed, RPM Size GG HJ, HL AS, AK, AL For a complete explanation of NPSH, see Application Data Sheet AD-9. FOR VISCOSITIES ABOVE 750 SSU (NPSH R data not available): The performance curves are based on 5 In.-Hg. While vacuums up to In.-Hg. will not generally result any loss of capacity, it is recommended that the suction le size and possibly the pump port size be creased to hold the expected vacuum to 5 In.-Hg. or less. Vacuum above In.-Hg. should be avoided. (Refer to Vikg s General Catalog, Engeerg Section 50, and Engeerg Service Bullet ESB-56 for formation helpful determg suction le size). THIN LIQUIDS: The 28 SSU curves should be used when applyg the Series 497 pumps to such liquids as water, aqueous solutions, alcohols, solvents, etc. MECHANICAL EFFICIENCY: The Mechanical Efficiency (expressed percent) can be calculated usg the followg formula: (Differential Pressure, PSI) (Capacity, GPM) (00) Mechanical Efficiency = (Horsepower, BHP) (75) METRIC CONVERSION: The followg table has been compiled for conversion to metric values.
