The self-priming engine-driven pumps, RW series, are centrifugal with an open impeller and large free solids passage, assisted by the large-capacity volumetric vacuum unit that enables constant self-priming even with very long pipelines.
Designed for a dual function to keep a constant vacuum in a wellpoint system and to transfer sewage and slurry. Priming is completely automatic avoiding the need to add water (dry-prime) and can operate even in dry conditions (dry-run).
The RW pump series can be used for the suction of any type of ground water, including seawater, in wellpoint systems, or for the suction in septic tanks and reservoirs of sewage, slurry with suspended solids, and so on.
