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. Accuracy? Uncompromising. Value for money? The best.
The stroke length and stroke rate – in this case the motor speed – can be adjusted to alter the capacity 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 non-return valves prevent the feed chemical from flowing back during pumping.
The pumps offer a very wide performance range. They also offer extremely accurate metering even under fluctuating pressure conditions (rigid characteristic curve). This results in reduced chemical consumption and precise process control.
Need a higher performance class? These pumps always deliver robust, low-cost power. They are also flexible: they can be controlled via the stroke length and motor speed, allowing them to be seamlessly integrated and/or retrofitted in automated processes. Energy consumption depends on the power required, not the other way round. And lastly, specially designed metering profiles allow optimum metering results.
The multi-layer safety diaphragm with diaphragm rupture indicator offers maximum safety. There is also an overload shutdown to protect the pump.
