New design magnetic rod assemblies, easily installed in sumps and easily cleaned, greatly reduce the solids load on coolant pumps or in-line filters for metalworking operations machining steel or cast iron. The new low cost in-sump magnets consist of a powerful rare earth magnetic rod attached to a flat circular magnet base, permitting the rod to be mounted either horizontally or vertically in the sump. The magnetic separator may be easily removed for cleaning and quickly re-installed in the sump. By mounting the magnetic separators close to the inlet of the coolant pump, the solids load on the coolant pump can be greatly reduced.
Coolant Filtration Yields Significant Savings
While many shop managers intuitively understand the importance of properly maintaining coolant, it's likely that few have calculated the actual cost savings of doing so. Keller Products says the 80-percent savings realized by one customer after installing pump/skimmer units is typical.
High-Capacity Bag Filters
To prevent deterioration in cutting fluid chiller performance, Keller Products features a line of bag filters that removes virtually all particles as fine as 1 µm from the fluid before it enters the chiller. The bag filters, rated for flows ranging from 30 to 160 gpm, have ¾" or 1 ½" NPT inlet and outlet fittings. The filter bags, available with retention efficiencies from 1 to 100 µm, have high solids holding capacity and are easily changed in a few minutes without tools, the company says.

Separator Solves Tramp Oil Dilemma
Debco Machine, Inc. (Natick, Massachusetts), a job shop specializing in precision components from aluminum, plastics and stainless steel, was faced with what it characterized as a particularly demanding requirement for tramp oil removal from the sump of a Matsuura 510 vertical machining center, a machine that is in nearly constant use. About 1 gallon per day of tramp oil enters the 100-gallon coolant sump of this machine.
A Separator Solves The Tramp Oil Problem
With their strong attention to routine housekeeping, it's not surprising that this shop carefully researched all methods for removing tramp oil from coolant in machine sumps. If tramp oil is allowed to build up in the coolant, the resulting shop odor, smoke generation and unpleasant conditions for the operators will quickly undermine all efforts to keep a clean shop and maintain an optimum working environment.
