Common Ways to Adjust Flow Rate on a Metering Pump
2025-02-05
Stroke-Length Adjustment
Flow is adjusted by changing the stroke length of the piston. While the metering pump is running, the stroke can be adjusted with a manual or electric stroke-adjustment mechanism. The longer the stroke length, the greater the volume of liquid the pump discharges per stroke, and the higher the flow rate; the shorter the stroke, the lower the flow rate. This method offers relatively high adjustment precision and is well suited to applications that require accurate flow control.
Stroke-Frequency Adjustment
This method adjusts the operating frequency of the metering pump — that is, the number of strokes per unit of time. The higher the frequency, the more times the pump discharges liquid per unit of time and the higher the flow rate; the lower the frequency, the lower the flow rate. A variable-frequency motor, a speed controller, or similar equipment can be used to change the pump's operating frequency. This adjustment method responds quickly and allows fairly flexible flow control.
