The Eriez HydroFlow 15-gallon (56 liter) Tank Side Coalescer removes tramp oil and fines and returns clean, reusable coolant to machine tool sumps and parts washers. This portable unit has a 1 to 1 ½ gpm oil removal rate and comes with nine-foot suction hose and five-foot clean discharge hose.
The Tank Side Coalescer features a 110-volt electric submersible pump, coupled to an adjustable skimming device which, when installed properly, rests in the sump and collects oil from the surface. The pump delivers skimmed tramp oil and coolant to the coalescer settling tank.
A 15-gallon polyethylene drum, an inner oil diversion baffle, an oil discharge spigot and a clean coolant discharge hose are part of the settling tank. Clean coolant gravity flows from the settling tank through the discharge hose and pack to the sump. The skimmer can be modified to work in machine sumps with as little as three inches of coolant.
Removing any tramp oil that leaks from a machine tool into the metalworking fluid should be a priority within any metalworking plant.
Using the Eriez HydroFlow Tank-Side Coalescer provides many benefits, including:
Decrease in smoke and dust
Increased tool and coolant life
Increased parts washer bath life
Decreased skin irritations, such as Dermatitis
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.
- 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.
- 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.
