## Description

Diaphragm pump for water or air, ideal for DIY projects, cooling, dosing and micro-installations. It operates at 6-12VDC, with the voltage you can easily adjust the flow rate of approximately 1.5-2 L/min, it has low noise and can suck up to 2 m, lift up to 3 m. Includes rubber mounts to reduce vibrations.
The pump can be used for both water and air, depending on the need and the project. The pump produces a fairly low operating sound level. The mode of operation is through the diaphragm.
Depending on the applied voltage, the flow rate increases or decreases.
The pump comes with rubber vibration dampers (supports).
Pay attention to the polarity of the product.
