Pump Calcs is a bundle of 30 useful calculators developed specifically for fluid machinery professionals. Pump Calcs equations can be used for the design and selection of centrifugal pumps, positive displacement pumps, electric motors, and machinery components. Every pump professional should have this time saving app on his or her smart mobile device.

Useful Calculator Features:
· Easily solve for the unknown value in an equation— App users can automatically solve for the missing value in a Pump Calcs equation by simply filling in values for all the terms you do know and pressing the “solve” button. The Pump Calcs app will then provide the correct answer by solving the required equation form to determine the missing term.

· Built in unit conversions— Most of the Pump Calcs calculator inputs boxes have automatic unit conversions built into them. For example, if you are inputting a value for horsepower, you can change the units from horsepower to kilowatts by pressing the “horsepower” button and scrolling the unit conversion wheel until “kilowatts” is displayed. The app will automatically apply the correct conversion factor to the calculation. If desired, this same unit conversion procedure can be used to change the output units well.

· Favorite Calculators— If there is a calculator you use frequently and would like to save it as a favorite, you can easily add it to your list of favorite by pressing the “Add to favorites” at the bottom of the input screen.
