Related Glossary Terms
Any manufacturing process in which metal is processed or machined such that the workpiece is given a new shape. Broadly defined, the term includes processes such as design and layout, heat-treating, material handling and inspection.
Minimum and maximum amount a workpiece dimension is allowed to vary from a set standard and still be acceptable.
- tramp oil
Oil that is present in a metalworking fluid mix that is not from the product concentrate. The usual sources are machine tool lubrication system leaks.
Portable coalescers from Eriez Hydroflow are suitable for metalworking plants with multiple machines. These simple, effective, low-cost tramp oil separators can be quickly and easily moved from machine to machine.
Eriez’ portable coalescer uses an oleophilic (oil attracting) coalescing plate pack media to remove oils effortlessly and efficiently. This plate pack consists of over 100 sq. ft. of coalescing area for maximum oil removal. The unit is equipped with a standard electric submersible pump, but can be upgraded with an optional air pump or a heavy-duty electric pump for deeper sumps. The Eriez portable coalescer can also be used on high-temperature fluids such as heavy-duty cleaners.
Because of its portability, a single machine can support tramp oil removal for an entire metalworking shop. These units can also be made stationary to work on large sumps or central systems. Larger flow rate systems can also be custom engineered to meet customers’ needs.
Reducing tramp oil is a high priority for all metalworking shops. Excess tramp oil leads to smoke, mist and bacterial infestation of the metalworking fluids, and adversely affects surface finish and reduces tool and dimensional tolerance control. Installing the Eriez portable coalescer extends the life of coolants and cleaners, improves machining and preserves valuable tools.
Standard features include adjustable feet for leveling, adjustable oil removal weir pipe, tank lid, floating oil collector to skim off oils and dirty fluid, pre-pump strainer and tank drain valve for cleaning. Options include self-priming centrifugal pump for pumping below ground sumps, 316 stainless steel tanks for high or low pH fluids, larger tank sizes and flow rates, 110-volt 50 hertz and 220-volt 50 hertz operation.
