ProMinent® – Solenoid-Driven Metering Pumps
What they do
Solenoid-driven metering pumps are available in capacities ranging from 0.74 to 80 l/h at a back pressure of 25 to 2 bar. To be able to meter almost any liquid chemicals, ProMinent uses a very extensive range of materials.
How they work
A solenoid moves the solenoid shaft forwards and backwards by switching on and off. This stroke movement is transferred to the diaphragm in the dosing head. Two check valves prevent the feed chemical from flowing back during pumping. But that’s not all. The stroke length and stroke rate can be precisely adjusted to alter the metering rate of ProMinent solenoid-driven metering pumps.
Where they are used
- General: Metering of chemicals of between 1 ml/h and 80 l/h
- Potable water treatment: Metering of disinfectants
- Cooling circuits: Metering of corrosion inhibitors and biocides
- Wastewater treatment: Metering of flocculants
ProMinent® – Motor-Driven Metering Pumps
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.
How they work
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.
Where are they used
- Chemicals up to over 1,000 l/h
- Disinfectants in potable water treatment
- Disinfectants in cooling circuits
- Flocculants in wastewater treatment
ProMinent® – Peristaltic Metering Pumps
What they do
Peristaltic metering pumps are used in a capacity range of between 10 ml/h and 410 l/h. They pump against a pressure of up to 8 bar. The incredible durability and wide range of chemical compatibility of the high-performance hoses used by ProMinent are particularly impressive.
How they work
The hose in contact with the housing is disconnected by rollers sitting on a rotor. The rotary movement of the rotor moves the disconnected point in the desired pumping direction and the medium is pumped. Once the roller has pressed the medium through the hose in the dosing head, the hose is relieved again. The hose lines up again, produces negative pressure and fresh medium is drawn into the hose.
The feed rate can be increased in a linear fashion by increasing the rotor speed.
Where they are used
- Wastewater treatment: Metering high-viscosity media / polymer solutions
- Potable water treatment: Metering of disinfectants
- Cooling circuits: Metering of corrosion inhibitors and biocides
- General: Chemical metering up to 410 l/h
