About Harbison-Fischer

With the Harbison-Fischer production calculator app, you can dynamically adjust the sucker rod pump parameters and calculate output easily! Just ‘dial-in’ the Pump Size, Stroke Length and Strokes Per Minute and instantly view the estimated production output in imperial or metric units. It also lets you know when the maximum linear stroke velocity could exceed the fall speed of the sucker rods.
