Variable Speed Pumping

An infinitely variable flow may sometimes be more appropriate. The chapter explains the usage of variable speed concepts in pumping systems and some potential problems related to the use of the electronic variable speed drives (VSDs) in pumping systems. ... The chapter discusses the pumps that are classified under the principle—such as.

John Infinitely Variable Transmission (IVT™)

-10-5 · Speed control lever The speed control lever controls the commanded speed of the tractor. This speed is variable from a very slow speed at the bottom end of the first band up to the preset set speed 1 at the end of the first speed band. The commanded speed is then variable from set speed 1 to set speed 2 at the end of the second variable speed ….
