TOP-FLO Pump Sizing Application Data

1 4 Use of a Pump Curve ChartTOP-FLO Pump Sizing Application DataThe curve chart is the best resource to use when selecting the proper impeller and motor for applications in the food, dairy, beverage, pharmaceutical and cosmetic industries. The curve chart enables the user to determine how a pump will perform at different impeller sizes and motor at 1750 RPM and 3500 RPM, curves have been listed for the TOP-FLO TF-C100, TF-C114, TF-C216, TF-C218, and TF-C328 centrifugal pumps on the following pages. An instructional chart is listed : Column #1 on the left shows head in feet Row 1 at the bottom shows gallons per minute Impeller sizes are listed on curve line Motor horsepower listed on diagonal serrated lines NPSH required is #3 and listed at the bottom of chartExample: On the curve listed below, find the impeller size and horsepower of motor for 75 GPM against total head pressure of 40'.

2 HEAD IN GALLONS PER MINUTEC olumn #1 Row 1 Answer to example: 1. To determine duty point: First, find the 40' of head in column #1. Second, find the 75 gallon per minute in column #2. Then, trace the 40' of head mark to the right until it intersects the 75 GPM To determine impeller diameter. The duty point falls between the and impeller curve lines. Always choose the curve line above the duty point. In this case it would be To determine NPSHR (Net Positive Suction Head Required): Use the NPSHR graph and plot the intersection point of 75 GPM. Follow horizontally to the left. It reads 9'. (This will be Net Positive Suction Head Required.)4. You will see at this point a impeller and a 1-1/2 horsepower motor is : NPSHA (Net Positive Suction Available) must be > or = NPSHR (Net Positive Suction Head Required).
