SERIES DESCRIPTION Vikg s Motor Speed Product Le Series 493 and 493 steel external pumps are available capacities up to 75 GPM. These pumps can be furnished directly connected to a 50HZ or 60 HZ motor. Series 493 is designed for vertical or horizontal flange mount stallations where space is at a premium. Series 493 is designed for foot type horizontal mountg. These pumps are built for contuous or termittent duty for such applications as filterg, circulatg, trans ferrg, or booster service general dustrial, petro chemical and other dustries. They are furnished as standard with mechanical seal construction to mimize liquid loss and for shaft protection. The thrust control provides micrometer adjustments for accurate rotor and shaft positiong to help you keep operatg with new-pump efficiency through years of heavy duty service.

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 (Net Positive Suction Head vailable the system) must be greater than the NPSH R. For a complete explanation of NPSH, see pplication Data Sheet D-9. FOR VISCOSITIES UP TO 750 SSU See NPSH R table below. NPSH R for high viscosities can be estimated usg the followg method:. Calculate le loss for a foot long pipe of a diameter matchg the pump let port size. Use your flow rate and max viscosity. 2. Convert this value to Feet of Liquid (S.G..0) 3. dd this value to the NPSH R value the chart below.
