Abstract

Det er beskrevet en anordning ved pumpestasjoner inneholdende to eller flere pumpeaggregater (4), (5). Pumpenes trykkledninger (8), (9) er forbundet med en shuntledning (10), som holdes åpen en kort tid ved pumpestart, hvorved det skjer en tilbakespyling gjennom den eller de pumper som ikke arbeider for øyeblikket, slik at forurensninger føres bort.A device is described at pumping stations containing two or more pumping units (4), (5). The pump pressure lines (8), (9) are connected to a shunt line (10), which is kept open for a short time at the pump start, whereby a backwash occurs through the pump (s) that are not currently working, so that contaminants are removed.
