The Etatron Dl Ma pump is designed for dosing harmful and/or toxic liquids. Its operation is ensured by a Teflon membrane mounted on the piston of an electromagnet. When the piston is attracted, pressure is generated in the pump body, allowing the liquid to be expelled from the delivery valve. At the end of the electrical impulse, a spring returns the piston to its initial position, allowing the liquid to be drawn in through the suction valve. This pump requires no lubrication thanks to its simple operation, and maintenance is virtually non-existent. The materials used in its construction make it suitable for use with particularly aggressive liquids. Flow rate: 0 to 80 l/h Pressure: 0 to 20 bar Power supply: 100-240 V - 1 A - 50/100 Hz
