Brushed Liquid Diaphragm Pump Pressure Test: 600 mL/min Class
Watch a brushed liquid diaphragm pump pressure test and see why its 600 mL/min free-flow rating must be evaluated separately from pressure capability.
Watch the brushed liquid pump pressure test
What does the brushed liquid pump pressure test establish?
Pressure capability and useful liquid flow are different selection inputs. The source video presents the brushed DPL60, described with 600 mL/min flow and a 100 kPa maximum pressure specification. The short demonstration does not establish continuous delivery at both values together.
Identify the pressure being read
Record whether the pressure is measured at the pump outlet or elsewhere in the circuit, and whether liquid is still flowing. A gauge reading alone cannot define the usable flow-pressure operating point.Confirm the brushed motor configuration
Compare voltage and motor type with the selected product. A pressure result from one motor and supply setting should not be silently applied to another configuration.Check the required running condition
For repeated wash or transfer cycles, evaluate flow, current and temperature over the intended duty cycle. Use the current specification for operating limits rather than treating the end of a short test as a continuous rating.
Review the brushed pump and compare its brushless alternative
DPL60-DB is the relevant brushed configuration. DPL60-BB is included for motor-option comparison; the video does not report its pressure test. Confirm the exact electrical and wetted-material configuration before selection.
