Eriez SumpDoc reduces need to dump, refill fluid

Eriez SumpDoc coolant maintenance equipment combines both sump cleaning and tramp oil removal in one package. According to the company, the unit keeps coolant clean longer, decreasing the need to dump and refill fluid.

The machine serves as an alternative to a central fluid recycling system or batch processing. It supplies complete coolant restoration and rejuvenation treatment of the metalworking fluids in the machine tool sump and requires minimal operator interface, says the manufacturer. The portable unit can be wheeled next to a machine tool, parts washer, or rinse tank to provide fluid reclamation.

Main components include a sump cleaner for removal of 50-µm and larger chips and solids, pleated bag filter and housing for removal of solids down to 10 µm, high-speed centrifuge for removal of emulsified tramp oil and fines down to 3 to 5 µm, an ozone generator for microbiological treatment of coolants, and electrical controls with a touchscreen dashboard.
