Motor-Driven Metering Pumps

It's all thanks to the electric motor

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.

Well adjusted

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 motor-driven metering pumps can handle the following substances:

  • Chemicals up to over 1,000 l/h
  • Disinfectants in potable water treatment
  • Disinfectants in cooling circuits
  • Flocculants in waste water treatment
  • Additives in the paper industry
  • Additives in plastic manufacturing

Impressive benefits

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.

Stay in control

The multi-layer safety diaphragm with diaphragm rupture indicator offers maximum safety. There is also an overload shutdown to protect the pump.

Pump Guide

The choice of pumps is huge: 80 industries, 100,000 products and infinite applications. To make it as easy as possible to find your ideal metering pump, ProMinent designed the Pump Guide. All it takes is a few clicks to find a selection of suitable models.

How it works

First enter the pump capacity and back pressure. The Pump Guide will then show you all the metering pumps that match your criteria. You can choose between list view and detail view. The database contains all solenoid-driven metering pumps, motor-driven metering pumps, process metering pumps and peristaltic pumps from ProMinent. They are divided into more than 30 different product ranges.

Exactly the right pump

Narrow down your search by clicking on different selection criteria. Do you have a specific industry, operating mode, medium or viscosity in mind? Or maybe you need a pump for zones at risk of explosion? The Pump Guide will take you to the pump you need with just a few clicks.
