Keller TKO Tramp Oil Skimmers for single sumps
The air-driven Keller TKO Tramp Oil Skimmer rapidly sweeps out tramp oil, cleaning and aerating the entire sump.
Benefits
- Extended tool life, improved parts finish
- Smoke and odor eliminated
- Multiplied coolant life = much less machine downtime, greatly reduced coolant purchase and disposal costs
Exclusive Keller advantages
- Superior tramp oil separation – The Keller patented permanent oil separating/coalescing element provides extraordinary surface area in a small package, providing excellent oil splitting in a compact design.
- Rugged construction – By using only 1/2″ air-driven pumps, Keller has eliminated the numerous operating and reliability problems associated with electrical pumps or smaller air diaphragm pumps.
- Ease of setup and operation – A TKO unit ships UPS in one box, and setup time is about 15 minutes. Only a 1/4″ compressed air line is required to run the unit. Minimal operator attention is needed.
- Inexpensive – Even including the 1/2″ air pump, the unique Keller TKO compact design is 30% to 50% less costly than other comparatively equipped systems.
How the TKO Works
The self-priming air operated pump pulls the tramp oil/coolant mixture from the surface of the sump through the floating inlet device, then through a cartridge filter which removes any chips from the fluid. The oil/coolant mixture is then pumped through the patented Keller all-plastic separator element immersed in a separator tank. The cleaned coolant continuously returns to the sump. The oil layer collects on the top of the separator tank and is occasionally drained into a waste oil container, simply by opening the oil drain valve. No other operator attention is required.

| Tramp Oil Loading | Moderate | Heavy | Very Heavy |
| Coolant Oil Rejection Rate | Efficient | Slow | Slow |
Each TKO Separator is shipped by UPS complete, ready for setup and includes (1) #RSM-3 Floating Inlet Device. Customer supplies only a 1/4″ compressed air line. The unit may be set on the floor adjacent to the sump, or the TKO-6 can be hung on the machine tool using the CLO-1 magnetic frame (see photo).

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.
