Low Pressure Metering Pumps

Our metering technology allows fewer chemicals to be used in numerous processes. For our customers, this means reduced costs, economical metering and environmental sustainability.
Our proven design principles guarantee a high standard of quality and precision. Sophisticated monitoring functions ensure reliability in operation. And minimal chemical consumption with optimum disinfection. Microprocessor technology allows the pumps to be controlled with accuracy. Interfaces integrate the pumps into a fully automated process.
Alongside individual components for metering liquids, we also supply complete metering systems. If requested, the entire system is supplied wired for use. Alternatively, the system can be installed and taken into operation on site by our technicians.

How do metering pumps work?
Most metering pumps are oscillating displacement pumps (diaphragm and plunger pumps) or peristaltic pumps. With oscillating displacement pumps, an exactly defined volume of liquid is drawn into the displacement body on the reciprocal stroke and forced into the dosing line on the compression stroke.
The pump settings can be changed to achieve consistently accurate metering. With a peristaltic pump, an exactly defined volume is pumped by clamping and squeezing a hose. Liquid is drawn in again by raising the hose into a neutral position.

Find the right pump type:

• 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

Diaphragm 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.
