Pressure = Head (Feet) x Specific Gravity(PSI) 2.31
Head = Pressure (PSI) x 2.31(Feet) Specific Gravity
Vacuum = Dynamic Suction Lift (Feet) x .883 (Inches of Mercury) x Specific Gravity
Horsepower = GPM x Head (Feet) x Specific Gravity(Brake) 3960 x Pump Efficiency
Horsepower = GPM x Head (Feet) x Specific Gravity(Water) 3960
Efficiency = Horsepower (Water) x 100 Per Cent(Pump) Horsepower (Brake)

USEFUL PUMP FORMULAS
Affinity Laws: Effect of change of speed or impeller diameter on centrifugal pumps.

Designed with preselected impeller diameters and motor horsepower sizes to offer better availability.
Pump Construction: Bronze Fitted Motors: 208-230/460 VoltsStandard Mechanical Seal 3 Phase, 60 HertzMaximum Working Pressure 175 psi Open Dripproofwith 125# ANSI Flanges
HOW TO USE THIS BOOKLET
• Determine the Pump Model number from the quick selection charts on the cover of this Booklet. Requireddata: Pump Flow and Head and desired RPM. Use the Standard Pumps shown on this page when possible.
• Consult the individual pump curve for the desired pump model to determine the required motor horsepower,pump efficiency and NPSHR.
• For faster, computerized pump selections, consult your ITT Bell & Gossett Representative about ESP-PLUS,Bell & Gossett’s Equipment Selection Program for personal computers.
