2-Wire Brushless Diaphragm Pumps: Power Connections and Selection
Explore a two-wire brushless diaphragm pump interface and compare simple power connections with the control and feedback needs of an instrument.

When is a two-wire brushless pump interface suitable?
A two-wire brushless configuration offers a simple power connection when separate control and feedback leads are not required. The source demonstrates this approach with a DPL60 pump; choose it around the control behavior your instrument actually needs.
Power polarity and voltage
The demonstrated wiring identifies red as positive and black as negative. Check the supplied motor's label and wiring specification before applying power; do not extend this color convention to every pump or cable assembly.On/off control versus speed feedback
Two power wires do not provide a separate FG output. If the instrument requires a speed command or rotation feedback, review a control-equipped motor configuration and its interface requirements.Confirm permitted supply control
Do not assume that arbitrary supply-voltage reduction or power-line PWM is acceptable. Ask for the supported control method, startup behavior and protection requirements for the selected two-wire driver.
Select a brushless pump with the required electrical interface
Review the DPL60-BB family and specify whether the application requires two-wire operation. Confirm the offered motor configuration separately from the fluid flow and pressure requirements.
