Motor Driven Metering Pumps

Focus on PUMPS.jpg

What they do

Motor-driven metering pumps need to be robust, reliable and able to run on their own without supervision. Metering pumps with mechanically actuated diaphragms can be used almost universally in low-pressure ranges. And what about servicing? Minimal. Precision? Uncompromising. Value for money? The best.

​

Well adjusted

The stroke length and stroke rate – in this case the motor speed – can be adjusted to alter the metering rate of this pump. The rotation of the electric motor is stepped down by a worm gear and converted into a linear stroke movement by a cam. The slide rod transfers this stroke movement to the diaphragm in the dosing head. Two check valves prevent the feed chemical from flowing back during pumping.
