600 mL/min Brushed Liquid Diaphragm Pump Flow Test
Watch a 600 mL/min class brushed liquid diaphragm pump flow test and review how inlet conditions, tubing and backpressure affect delivered flow.

How to compare a liquid pump flow test with your circuit
A measured flow rate is useful only with its operating conditions. This DPL60 brushed-pump video provides a short flow demonstration; the 600 mL/min catalog value should be read with the product's stated test conditions.
Record the measured quantity and elapsed time
When collecting liquid, calculate flow from collected volume divided by collection time. State the interval and repeat the measurement; a brief visual demonstration alone does not establish dosing repeatability.Include inlet height and tubing
The source mentions 3.2 mm internal-diameter hose for the suction-lift specification. Hose size, length, reservoir level and inlet restrictions also matter when comparing a bench setup with an installed liquid path.Measure with the outlet components connected
A filter, valve or elevated outlet can create backpressure that an open discharge does not have. Verify the target flow with those components in place rather than sizing the pump from free flow alone.
Compare brushed liquid pumps for the required working flow
Start with DPL60-DB for the pump family demonstrated. DPL30-DB is a lower nominal-flow alternative to compare when the liquid-transfer task requires less flow. Check each curve at the actual operating pressure.
