Programmable peristaltic pumps are advanced fluid-handling devices designed to deliver highly accurate, consistent, and controlled fluid flow. Unlike traditional peristaltic pumps, these models are equipped with microprocessors or PLC interfaces, allowing users to automate, customize, and precisely control flow parameters for a wide range of applications.
How Does a Peristaltic Pump Work?
A peristaltic pump operates on a simple but effective mechanism: a set of rotating rollers compress a flexible tube, pushing fluid forward through the tubing. The fluid does not come in contact with any mechanical components—only the inside of the tubing—making the pump ideal for sterile or corrosive applications.
What Makes It “Programmable”?
The key differentiator lies in the control system. A programmable peristaltic pump integrates digital interfaces such as:
-
Touchscreens or LCD interfaces
-
External control via RS232/RS485, USB, or Ethernet
-
Flow calibration and auto-tuning
-
Step-by-step programming for complex cycles
Users can predefine:
-
Flow rates (e.g., in mL/min or μL/min)
-
Dispensing volumes and intervals
-
Time-based operations (start/stop cycles)
-
Alarm and error response behaviors
Some models even support remote monitoring or integration into SCADA or laboratory automation systems.
