4 INTENDED USE
NORMA-V pumps are used for handling of clear, slightly turbid or
particle containing fluids.
Thanks to its submerged hydraulic design, the pump is not concerned by
priming or sealing problems.
Various materials and construction variants are available to match major
industrials and OEM needs.
NORMA-V pumps are used in every kind of industrial plants, in surface
treatment process, in machining units, for lifting of high temperature
condensates, rain water, oily water, …
5 DESCRIPTION
