The R4 pump has a vertical centrifugal pump with and open impeller located in a chamber and easily tolerates suspendedparticulate liquids.
This pump operates under the principle of negative pressure; the tightness’s single function is to stop air from entering and the liquid from exiting (no risk of liquid pollution to the outside elements).
Traditional locations for this type of pump is on the edge of a pit or tank, or directly on a cistern. It comes in different materials:
- Stainless steel (316L, Duplex, Hastelloy…)
- Plastic (PP, PVDF…)
The R4 series pumps are self-priming and their technology allows for pumping regular or suspended solid liquids and all while ensuring complete protection of the environment.
