Oil Skimmers

Why should I have oil skimmers on my machines?
  • In most machine tool coolant systems and detergent wash systems, tramp oils are the number one contaminant.

  • In coolant systems, tramp oils collect on top of the coolant sealing off oxygen and promoting the growth of anaerobic bacteria. The bacteria feed on tramp oils and the components of the coolant.  It also produces offensive hydrogen sulfide gas (Monday morning smell).
  • By removing tramp oils using oil skimmers, bacterial growth can be reduced or eliminated and sump life can be greatly increased.
  • In wash systems, tramp oils can leave residues on parts. By using oil skimmers to remove them, the bath life can be extended.
  • Most oil mist is more tramp oil than coolant and poses more of a health risk than coolant mist only.  Removing tramp oils with an oil skimmer can reduce the amount of oil mists.
  • Some tramp oils, such as hydraulic fluid, can react with the coolant causing splitting and accelerated bacterial growth, resulting in premature pumpouts. They can also be an irritant to the operators.
  • Tramp oils can also cause accelerated tool wear, as they do not have the machining properties of the manufacturers' lubricants.

 

Oil skimmers can also be used to remove petroleum, vegetable, or synthetic oils and also greases from process tanks, holding tanks, or catch basins. Virtually any liquid floating on top of another liquid can be removed with an oil skimmer using the correct belt or other material.  Non standard applications may take some experimentation.

 

Belt Skimmers

The Skimpy Standard is our most popular belt skimmer, along with the Skimpy El Nino. Abanaki is one of the world's leading oil skimmer manufacturers, and we are excited to offer their line of coolant maintenance products, starting with the Mighty Mini SST belt oil skimmer. The Cedarberg EZ-Skim's unique design works in both deep and shallow tanks. Wayne MSB-B skimmers with all stainless steel metal parts are ideal for parts washers, hot and/or caustic applications. Wayne SSP2 and SSV5 belt oil skimmers are corrosion-proof and suited for more heavy-duty applications. Zebra Skimmers offers standard size oil skimmers up to 24" reach in both poly and stainless steel belt models.
 

Disk Skimmers
Disk Skimmers

Disk skimmers work by mounting to the top of the tank and running a large diameter disk into the coolant surface. The disk itself is made of either plastic or stainless steel. As the disk passes through the coolant surface, oil is picked up and wiped off with a set of wiper blades as the disk passes between them.

Advantages for disk skimmers are a slightly higher pick up rate than other types of skimmers and lower cost.

Disk skimmers do require a larger operating space to accommodate the disks.  The pick up rate drops dramatically if the fluid level does not cover at least half the surface of the disk, making it unsuitable in tanks where the fluid level fluctuates. 
 

Tube Skimmers

It’s the age old question; which is better? The belt skimmer or the tube skimmer for collecting floating surface oils from various applications? Some feel that belt skimmers work better because it takes up less space while still collecting oil from large surface areas. Other people feel that the tube skimmer works better because the tube covers more of the tank or pit’s surface. The fact is that both skimmers use the same principle of breaking the surface tension of the water to allow the oil to adhere to either the belt or the tube.
 

Tank-Side Coalescers
Tank-Side Coalescers

Tank side coalescing oil skimmers sit outside the tank and, unlike belt or disk skimmers, remove emulsified oils as well as the free floating oils. They can run continuously without overflowing, keeping the coolant moving and aerated. Over time a tank side oil skimmer will remove more oil than a belt or disk skimmer. Coolant Consultants offers three different brands of tank-side oil removal systems: Keller, PhaSep, and Zebra.
 

Portable Tramp Separators
Portable Tramp Separators

By removing tramp oil and aerating the coolant at high flow rate, Keller separators eliminate the source of shop odor and extend the life of cutting tools and coolant.  A Keller portable separator can clean a sump in a few hours and then may be moved to another sump and set up in minutes.  One Keller portable separator can keep 10 or more sumps clean.  The separators can be run while the machine tool is operating or when shut down.  Keller separators are shipped by UPS and ready to run, requiring only connection to a 1/4" compressed air line.  There are no electricals.  Thousands of Keller separators are in service.

Well Skimmers

The Wayne MAXI-skimmer™ Model MWM for wells is truly different from other belt skimmers! The generator speed is variable which means you can adjust the product collection rate to suit your needs.
 

Belt Mop Skimmers

Ambar manufactures oil sorbent rope mop and belt mop type oil skimmers that remove waste oil, grease, sludge and almost any hydrocarbon from the surface of industrial process liquids and waste waters. Ambar's versatile belt mop type oil skimmers outperform ordinary tube skimmer systems and operate in a wide range of industries.
