JOHN BLUE PUMP SETTING
The NGP pump output is determined by the drive sprocket ratio and the stroke setting. There are two ways to find
the proper setting for your pump.

Slide Chart (Supplied With Pump)
Using the slide chart shown in [Figure 28] , supplied with pump - follow example below:
SPROCKET RATION
Standard Sprocket Combinations
Standard sprocket combinations may be used for equipment with only one chain from the ground or press wheel
sprocket to the pump. For example: an applicator with a 60 tooth drive sprocket on the tire driving a 16 tooth driven
sprocket on the pump can use the 16 to 60 mark on the slide chart.
Non-Standard Sprocket Combinations
If using sprocket combinations with multiple sprockets, such as a jack shaft, use the following formula to determine
sprocket ratio:
For example: an applicator with a 50 tooth drive wheel, driving to a 24 tooth sprocket on the jack shaft, then a 36
tooth sprocket on the jack shaft driving up to a 16 tooth pump driven sprocket, would yield a 4.69 drive ratio.
Set the sprocket ratio on the slide chart using the 4.69 calculation for the example above.
