How the Keller TKO Separators work
Each separator is supplied with compact inlet devices which can access the surface of any sump through an opening as small as 3″ diameter. The oily coolant is pulled from the sump surface through a solids filter, a high capacity bag filter, which will significantly reduce the concentration of suspended solids in the sump when machining aluminum, plastics, or other light weight materials. The air-operated diaphragm pump has a suction lift of 15 feet and can be run dry or dead-ended without damage. The filtered coolant then flows through Keller permanent plastic oil separated elements immersed in a plastic tank. The coalescing separator elements cause the oil drops to form a layer that rises to the top of the separator tank. The cleaned coolant exits continuously via an overflow port and returns to the sump. The oil layer collected in the separator tank can be drained into a waste oil container by opening the oil outlet valve occasionally, usually once per day. No other operator attention is required.
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 separator model is selected based on:
- the sizes of sumps to be cleaned,
- the relative volume of tramp oil to be removed, and
- the quantity of suspended solids in the sumps.

INSTALLATION GUIDELINES
When setting up a coalescer, the fluid return hose should be located as far away from the oil pick-up as possible. It can also be used to “push” the tramp oil towards the pick-up unit. The oil pick-up needs to be positioned where the most oil is present if possible. The pick-up also needs to float freely with changes in fluid level. It’s usually best NOT to locate the pick-up near the pumps.
When setting up air powered coalescers, the air regulator should be adjusted so the pump is running really fast, then close the small air ball valve before the pump, reducing the air flow until the pump is running as slow as possible to maintain flow and suction at the pickup device. If you adjust the pump speed with the regulator, the pump can stall out or run too fast with slight changes in shop air pressure. The filter should be changed when flow becomes restricted. Sometimes the filter doesn’t look dirty, but has become “blinded off” by fine residues or contaminant coating.
All oil skimming devices should only be run when oil is present on surface. Timers should be used to activate the device after the oil has settled to the surface. Running them 24/7 just wears the motors out prematurely. Coalescers can be run periodically even if oil is not present on the surface in order to keep the coolant moving on an intermittently run machine.
