Elastomer - Coated Rotor Pump For High Abrasiveness Sewage Water
Application in sewage water
Sewage water occurs in almost all industrial operations and
processes and is one of the most complex forms of wastewater. This
is due, in particular, to the demanding composition of the pumps
and conveying systems. The contents range from dissolved and
undissolved, inorganic and organic substances to acidic and basic
media, oils, and poisons.
Despite the high abrasiveness of the sewage water, the Accuvon
rotary lobe pump offers you a particularly long service life. On
the one hand, this is due to the robust and durable design and, on
the other hand, to the material reversal. While other pump
manufacturers usually have elastomer pistons rotating in a metal
housing, this pump uses steel rotary pistons. The inside of the
pump is lined with a rubber insert. This gives you a high efficient
pumping capacity when pumping industrial sewage water.

Working Principle of Rotary Lobe Pump:
The rotary lobe pumps we also called them lobe rotor pumps. They
are one popular transfer pump to conveying the food, beverage, pulp
and paper, chemical, pharmaceutical and so on. The rotor lobe pump
relies on two synchronously rotating rotors that generate suction
(vacuum) at the inlet during the rotation. Thereby sucking in the
material to be conveyed. Both rotors split the rotor chamber into
different spaces. Then operate in the order of 1-2-3-4. The medium
is delivered to the discharge port. In this cycle, the medium
(material) is continuously transported out by the source.
