• Sets up in minutes – Requires minimal operator attention – Thousands in service

How to select the Keller Separator for your application:

A Keller portable separator can clean a sump in 3 to 4 hours, and then may be moved to another sump and set up in minutes. We recommend that each sump be cleaned once per week. A separator can clean two sumps in a single shift, or 10 sumps per week in a one shift 5 day operation. The machine tool may be operated while the Tramp Oil Separator is operating.

How the Keller Separators Work:

Each separator is supplied with three inlet devices (see below) which can access the surface of any sump through an opening as small as 3” diameter. The self-priming air operated pump pulls the tramp oil/coolant mixture from the surface of the sump via the inlet device, then through a high capacity bag filter, which removes chips from the fluid.

The oil/coolant mixture is then pumped through the patented Keller all-plastic separator elements immersed in a separator tank. The cleaned coolant continuously returns to the sump. The oil layer collected on top of the separator tank can be drained into a waste oil container by opening the oil drain valve occasionally, usually once per day. No other operator attention is required.

Inlet Devices

An inlet device draws oily coolant from the surface of the sump while avoiding the intake of air, which can interfere with splitting of oil from coolant in the separator tank. One inlet device is used in each sump.

The #555-07 Floating Inlet Device (7” wide x 10” long), the most frequently used inlet device, automatically compensates for any changes in the level of coolant in the sump.

The #555-07 and #555-17 (7” x 7”) may be used in pit-type sumps with liquid levels as much as 10 feet below floor level.

The #555-05 Floating Inlet Device (2” wide x 12” long) is used when only a narrow access space is available; for example, next to a conveyor.

The #555-06 Fixed Inlet Device requires only a 3” diameter hole for access to the sump but must be adjusted manually if the sump level changes significantly.

Since a Keller portable separator is to be rotated among several machines in sequence, it is most convenient to mount an inlet device permanently in each sump. The connection from the inlet device to the separator is a quick garden hose fitting.
