Single stage, vertical side channel pump with an open vane wheel impeller. The program comprises 3 sizes. Because of the vertical arrangement of the unit, the floor space requirements are low. If the pipelines are of sufficient stability, the units of this series can even be suspended in the piping system without any foot support.
The DRV pumps are used when clear or turbid liquids with an aggressive nature, in varied concentration and temperature ranges and without any abrasive particles, are to be handled reliably and trouble free. The performance curve steepness admits a precise regulation of the pressure with a small change in capacity. Their applications cover the private, professional and industrial fields for example domestic plants and agriculture (feeding spring well fountains, garden and lawn cultivation), trade and industry (handling coolants, sampling and chlorination processes in waterworks, running bottle washing machines, circulating buffer water in big centrifugal pumps), chemical and pharmaceutical industry for laboratory techniques and in the food industry.
