Peristaltic pump integration for precision bottle filling
Peristaltic pumps are essential in food and medical applications as they provide the manufacturer with a disposable fluid path. Hose sets are available to meet a variety of regulatory needs.
Peristaltic pumps are in the positive displacement class of pumps. With appropriate controls, +/- 0.2ml precision can be achieved and our work continues on improving this precision.
Our pump rate at this precision is 720ml/minute. We are intent on improving this as well.
Out of frustration with existing peristaltic pumps and born of a certainty we could improve things, our version of the classic traditional was designed. Enhancements such as peristaltic rotor tracking through encoder feedback enhance volumetric accuracy. Built in fluid leak detection and integration with the CP system's interlock chain provide assurance and confidence that even should problems occur, the system will react in a controlled way. The belt reducer incorporated in this design enables the low cost stepper motor to operate in its most efficient torque zone and provide the best possible fill rate while mitigating splash.
Only the bearings, motor, drive, tubing, and shafts are purchased. All other components of the pump are made efficiently in-house, making customizations easy. We can provide custom tube occlusion, rollers per rotor, and even multiple tube counts at need. Off the shelf 2, 3, and 4 roller rotors are available.
UPDATE: Long term production QC monitoring shows a repeatability of 0.50 ml. Recent testing with platinum cured silicone tubing has improved the volumetric accuracy bu 10% or +/-0.45 ml.
