How Does a Peristaltic Metering Pump Work?
The operation of a peristaltic metering pump is ingeniously simple yet highly effective. Let's break it down step by step:
- Squeezing Action: The pump's rotor compresses the flexible tube/hose against a stationary housing, creating a squeezing action on the fluid-filled tube/hose.
- Formation of Seal: As the rotor continues to rotate, the squeezed portion of the tube moves away, creating a seal between the suction and discharge sides of the pump.
- Fluid Discharge: The sealed portion of the tube progresses towards the pump's outlet, pushing the fluid forward in a precise and controlled manner.
- Tube Recovery: After the fluid is discharged, the tube returns to its original shape, ready to be squeezed again for the next cycle.
The peristaltic metering pump's operation relies on the principle of positive displacement, ensuring accurate and repeatable fluid transfer.
