Solutions for Tramp Oil Removal - To Optimize Filtration

Increased demands for high surface finish and close part tolerance create a greater need for manufacturers to purify coolants that are constantly being cycled through precision machinery. To serve the purpose well and for efficient operations, efficient machine coolant tramp oil removal is an absolute necessity.

In any industrial (metal working or metal forming) activity, fluid filtration towards the end is critical and for the same reason Tramp Oil removal systems are now procured to properly maintain the coolants.

Benefits of keeping machine coolants clean -

A - Extended life of the concerned machinery

B - Extended tool life

C - No leakage or odor/ less emission of smoke

D - Reduced coolant purchase and disposal price

Solution - Coolant Process Systems (CPS) for single pumps and portable systems for multiple pumps offer the best filtration techniques combined, to ease the task of purifying coolants and cleansing through to remove various oil mixtures.

Various types of Filtration devices -

A number of conventional methods are available for tramp oil removal. The most common methods are skimmers, centrifuges and coalescers. Here a few other types are explained below:

1 - Portable Tramp Oil Separator

This mobile centrifuge provides small metalworking plants with true, high-speed centrifugation. The tramp oil separator recycles fluids at the sump by placing both the suction and return hoses directly into the machine sump, removing free and emulsified tramp oils from water miscible coolants and aqueous cleaners. This process enables uninterrupted machine tool operation.

2 - Tank Side Coalescer

With a flow rate of 1.5 gpm, this small and inexpensive sump-side coalescing unit allows oils to rise naturally by providing a quiescent area not available in a turbulent sump. The tank side coalescer comes standard with a submersible pump or with an optional air pump.

3 - Surface Oil Skimmers

A deluxe model surface tramp oil belt skimmer has an oleophilic belt and a unique method of stripping the separated oil from both sides of the belt without contacting a stationary scraper. This design provides a nice combination of performance and long belt life.

4 - Self Cleaning Centrifuges

Self-cleaning centrifuges are designed for central fluid systems. They pull the fluid, remove tramp oils and small fines, and return cleaned fluid to the central system. This type of centrifuge package can be designed to handle any combination of central systems and individual machine tool recycling.The high-speed disc bowl centrifuges are available with a manual clean, solid wall bowl or an automatic self-desludging two-part bowl design. The automatic version is preferred in high solids applications and on central system equipment.
