Vertical Fine Screen ROTAMAT® RoK 4

Pumps in lift stations require a lot of maintenance. Pumps with a large clear passage are used to prevent frequent clogging. However, those pumps have poor efficiency, particularly where the flow is low. Grinder pumps are subject to high wear, thus also requiring frequent maintenance in a narrow and dangerous environment. Upstream screening protects pumps from clogging and permits use of high-efficiency pumps. In addition, removal of coarse solids protects sewers by preventing deposits and reducing septicity, odor and concrete corrosion.

The RoK 4 is the ideal screen for such applications. It is extremely compact and fits easily into confined spaces, such as wet wells and manholes. It vertically lifts the screenings, and dewaters and compacts them at the same time.
