300 mL/min Brushed Liquid Diaphragm Pump Flow Test
See a 300 mL/min class brushed liquid diaphragm pump flow demonstration and review the conditions needed to assess a compact liquid-transfer pump.

What to record in a brushed liquid pump flow test
A compact brushed liquid pump can be assessed by measuring the flow delivered through a defined circuit. This DPL30 clip is a short demonstration of the 300 mL/min class; use the current product specification and your own operating conditions for selection.
Voltage and operating interval
Record the voltage at the pump and how long it runs before and during measurement. Startup, priming and established liquid delivery should not be combined into an unexplained average.Volume, time and repeat measurements
Measure the collected liquid and elapsed time, then repeat under the same conditions. Average transfer flow and the repeatability of individual dispenses are different results and should be reported separately.Duty cycle and maintenance expectations
The flow clip is not a motor endurance test. Consider the actual starts, stops and operating time when comparing a brushed option with a brushless one.
Compare brushed and brushless pumps in the same flow class
DPL30-DB is the brushed configuration. DPL30-BB is provided as a motor alternative, so you can compare electrical integration and service requirements without confusing the two test subjects.
