Allgemeine Beschreibung

LEWA-Dosierpumpen / Prozesspumpen sind oszillierende Verdrängerpumpen. Der Volumenstrom wird erzeugt, indem ein durch Kolbenfläche und Hublänge vorgegebenes Hubvolumen in einem sich periodisch wiederholenden Vorgang verdrängt wird. Der Volumenstrom kann durch Veränderung der Hublänge und der Hubfrequenz variiert werden.

Aufbau und Wirkungsweise

LEWA-Dosierpumpen / Prozesspumpen bestehen aus den Baugruppen Antrieb, Triebwerk, Pumpenkopf und eventuell weiteren Anbauten (siehe Bild 1).

Antrieb

Der Antrieb (meist Elektromotor) liefert die Energie, die nötig ist, um das Förderfluid von Saug- auf Förderdruck zu bringen.

Triebwerk

Im Triebwerk wird die Drehbewegung des Antriebs in eine oszillierende (hin- und hergehende) Bewegung des Verdrängers umgewandelt.

Pumpenköpfe (siehe Bild 2)

Der Pumpenkopf als eigentliches Förderorgan kann als Kolben- oder Membranpumpenkopf ausgeführt sein.
