Peristaltic Pumps DULCO®flex for Applications in Industries and Laboratories

Peristaltic Pumps manufactured by ProMinent are characterised by their simple functional principle and their compact, robust design. They are self-priming, without gaskets and valves.

The peristaltic pumps of the DULCO®flex series for low, medium and high outputs with a large output range of 17 to 25,000 l/h and a large number of different hose materials are suitable for almost all metering and delivery tasks in industry and laboratories. While the peristaltic pumps for low pressures up to 8 bar are equipped with roller technology, pressing shoes are used for higher pressures up to 15 bar.

Because of their design, the hose is the only wearing part of the peristaltic pumps which, however, can be quickly and easily replaced.
