The Eriez Hydroflow Tank Side Coalescer is designed to sit behind a metalworking shop's machining center and skim free-floating tramp oil out of the machine coolant. With a flow rate of 1.5 GPM, this small, inexpensive sump-side coalescing unit allows oils to rise naturally by providing a motionless area not available in a turbulent sump.
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 Tank Side Coalescer extends the life of coolants and cleaners, improves machining and preserves valuable tools.
The operation of this unit is simple, yet effective. The submersible pump sits inside the coolant tank drawing coolant into the 15-gallon drum. The adjustable skimmer removes any tramp oil off the top layer of coolant. Through a gravity hose, the clean coolant is returned to the machining center sump. This low-maintenance Tank Side Coalescer is available with optional oil belt skimmer, air pump and larger electric pumps.
Related Glossary Terms
- coolant
coolant
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
- machining center
machining center
CNC machine tool capable of drilling, reaming, tapping, milling and boring. Normally comes with an automatic toolchanger. See automatic toolchanger.
- metalworking
metalworking
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.
- tolerance
tolerance
Minimum and maximum amount a workpiece dimension is allowed to vary from a set standard and still be acceptable.
- tramp oil
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.
