Jetting Results Help

Results and Options:

StoneAge tools offer tremendous versatility. Tools can be jetted to have more or less torque, thrust, or side hitting power. These options will provide operators with greater cleaning capabilities.

The jetting app will provide the best head offset and nozzle selection automatically. If you make changes to the chart you can select the Rest Nozzles tab to reset the app to the automatic results.

Each tool can be jetted for more or less pull. To do this, increase or decrease the jets and watch the Pull value change. The number must be a negative value which means the tool is pulling away from the operator.

The nozzle options include a Plug option in the drop down list. This can be used to generate more pull when chosen for the front nozzle and then larger nozzles are used on the rear ports.

Watch the warning label at the bottom of the “Results as Configured” table. A red warning label will show if the tool is configured above or below torque.

Warning explanations:

  1. Under Torque: This typically means your desired flow is too low. Increase desired flow, try a higher R value option, or look for alternative tool family option.

  2. Over Torque: This typically means your desired flow is too high. Decrease desired flow, try a lower R value option, or look for alternative tool family option.

  3. Actual Flow exceeds Pump Flow: When this warning is illustrated you must confirm that your desired flow is within the tool design minimum flow, try using a plug in the front port, or choose a higher R value head option.
