How do metering pumps work?
Most metering pumps are oscillating displacement pumps. An exactly defined volume of liquid is drawn into the displacement body on the reciprocal stroke and forced into the metering line on the compression stroke. The pump settings can be changed to achieve consistently accurate metering.
Microprocessor technology since 1988
The accurate control of the pumps is made possible by microprocessor technology. Sophisticated monitoring functions ensure reliability in operation and minimum chemical consumption and optimum disinfection. Interfaces integrate the pumps into a fully automated process.
Over one million of our pumps are in use all over the globe, delivering reliable, accurate performance under the toughest conditions. Our proven design principles guarantee a high standard of quality and precision.
The product range
Large choice of types, wide range of capacities: from a few ml, e. g. for laboratory use, to 40,000 l/h, e. g. for use in process engineering.
The technologies in detail:
- Diaphragm metering pumps (mechanically deflected diaphragm)
- Hydraulic diaphragm metering pumps (hydraulically deflected diaphragm)
- Plunger metering pumps
- Peristaltic pumps
Classification by pump drive:
- Solenoid-driven metering pumps
- Motor-driven metering pumps
- Pneumatic metering pumps
Find the right pump type in four steps
- Specify pump capacity in litres per hour [l/h]
- Specify back pressure in bar
- Find the intersection of these two values and select the pump type that lies nearest to it
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.
