Gear Drive Selection
The Following Information Should Be Supplied When Ordering Gear
Drives:

Model number and ration (input to output speed). Thrust requirements, rotation, horsepower requirements and pump head shaft size. (We define the ratio as the ratio of the horizontal input RPM to the vertical output RPM.) EXAMPLE: A 2:3 ratio gear drive operating at 1760 RPM output would have 1173 RPM input.

ROTATION: Shown below are four possible rotations. Number 1 is considered standard. Unless noted differently, the drive will be manufactured to this configuration. Numbers 2, 3 and 4 are special rotations and are manufactured when specifically requested.
