Brushless Micro Liquid Diaphragm Pump Pressure Test
Watch a brushless micro liquid diaphragm pump pressure test and review the difference between nominal flow, pressure capability and installed performance.

What to verify before using a brushless pump under pressure
This video introduces the DPL30 brushless pump in a pressure-test context. Its 300 mL/min nominal flow and 100 kPa maximum pressure belong to different conditions; selecting a working point requires the flow-pressure curve and the intended motor configuration.
Keep the electrical configuration consistent
Record supply voltage, control method and test duration. A result from one drive setting is not a universal result for every brushless option or speed command.Observe liquid delivery as well as pressure
A circuit can reach pressure while delivering little liquid. Confirm the flow required by the downstream task, especially when a valve, narrow tube or filter introduces resistance.Evaluate the complete pressure boundary
Tubing, fittings, seals and downstream components must be suitable for the working pressure and liquid. Confirm startup and shutoff behavior rather than checking only the steady gauge reading.
Compare brushless liquid pumps for the required pressure
Review DPL30-BB for the demonstrated family and DPL30H-BS for a higher-pressure alternative. The higher-pressure model has different connections and must be evaluated as a separate configuration.
