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

• Waste water treatment: Metering high-viscosity media / polymer solutions
• Potable water treatment: Metering of disinfectants
• Foodstuffs industry: shear-sensitive media, aromas, additives
• Paper industry: Metering of additives
• Cooling circuits: Metering of corrosion inhibitors and biocides
• Plastics production: Metering of additives
• General: Chemical metering up to 108 gph (410 l/h)

What is unique about them

Our DULCOFLEX peristaltic metering pumps ideally combine the benefits of peristaltic pumps and metering pumps. They therefore support batch or proportional flow dosing, for example. Depending on the medium, they meter with a precision of up to ±1 %. They can be networked with our fluid management platform using DULCONNEX, making remote monitoring possible. They are just as reliable as our other metering pumps, are self-priming and can handle outgassing media with ease. Thanks to the ingenious hose replacement processes, this task is completed in no time and requires very little material.
