Every jetter has a certain amount of flow and pressure output. That output represents the maximum potential energy available for cleaning activity.  When the total orifice area is matched to the pump’s specifications, all the available energy is harnessed. However, if the total orifice area is not properly matched then performance suffers.  If the total orifice area too small, system backpressure prevents full use of the available system energy.   Likewise, if the total orifice area is too large, jet velocity and therefore pulling power are reduced.

At Aqua Mole, your pump’s pressure and flow specifications are  computer modeled to determine the optimum orifice size for your selected spray pattern.  Get the most out of your equipment with Aqua Mole’s custom orifice drilling.

As an added bonus, custom drilling allows Aqua Mole to supply our customers with special, or non standard spray patterns, generally at no additional cost, and with no shipping delays!

The correct drilling of a nozzle's orifices assures that all of the pump's energy is utilized. How that energy is utilized depends on the angle selection. For example, a long run will require a nozzle with more pulling power, so a 25° or 35° angle might be necessary. A totally blocked line will require a forward jet in combination with high thrust jets to break through the obstruction. Once a channel has been cut, switching to a flushing nozzle (45° or 55°) is useful for clearing the line. The drawing and table explain the various angle options and their functions.
