The Solution

The Solution – Consistent Dispense Results with Real Time Process Control (FPC) regardless of Reservoir Level

FPC provides a consistent feed of fluid to the dispensing pump regardless of reservoir fluid level or stopper stiction.  FPC monitors the pressure of fluid entering the dispense pump and makes adjustments to the reservoir feed pressure, resulting in a consistent feed to the dispense pump.

The chart below shows how inlet pressure to the pump can vary when constant pressure is applied. (1 min between tests)

The chart below illustrates how the Real Time Process Control system maintains the inlet pressure by adjusting the reservoir pressure.

FPC – Controller

When the feed pressure is consistent, dots will be uniform over the life of the reservoir.  Line or gasketing patterns will dispense in a uniform width and encapsulation processes will dispense a repeatable weight.

FPC applies to nearly all types of dispensing pumps based on a material feed or time and pressure:

  • Auger pumps
  • Jetting Valves
  • Pinch Tubes
  • Needle Valves
  • Even simple time pressure systems

FPC is available in all GPD Global dispense platforms.
