Product description
The R385 is a self-priming diaphragm pump for voltages between 6 and 12 V DC. An electric motor drives a flexible diaphragm via an eccentric cam, alternately drawing in and expelling liquid. Since no rotating parts operate directly in the liquid, the pump can handle minor contamination well.
The self-priming function allows the pump to start even when the intake hose is initially filled with air. Manual priming before operation is not required. With a flow rate of 1 to 3 liters per minute and a maximum pumping height of 3 meters, the pump is suitable for small to medium volumes of liquid in compact systems.
The motor draws more current at startup than the digital outputs of microcontroller boards can supply. It must therefore be controlled via a relay or a dedicated motor driver module connected between the control board and the pump’s two blade terminals. This makes it possible to build automatic irrigation systems, small aquariums or water circuits for cooling projects.
The pump can handle water as well as other liquids within the specified temperature range. One critical point is continuous operation without a liquid supply, which can damage the diaphragm and motor. The pump requires a separate power supply and a relay or motor driver module for control.
Safety notice
The pump must not run without liquid. It is intended exclusively for prototype assembly and testing and development purposes, and is not designed for connection to household mains power. If you have questions about the power supply or control, consult a qualified electrician before use.
