Miller Electric Reduces Oil Costs While Improving Part Quality-Image
Solution: SE30-140PT Sump Shark, DF4 Discharge Filter

Doug began working with Paul Elmer, CECOR’s application manager.  Paul suggested using a three-phase electric Sump Shark (model SE30-140PT) to clean the sump.  As the Sump Shark empties the sump, contents are filtered as they pass through the 2.3 cu.ft. onboard filter.

The DF4 discharge filter is used for a second stage of filtration. The DF4 filter couples to the discharge port and filters down to 10 microns as fluid is pumped out of the sump cleaner tank.


The SE30 Sump Shark cut cleaning time from 8 hours to less than two hours.  Doug says they now change the oil annually instead of every six to eight weeks.   “We also use it on another 12 machines using cutting oil as routine maintenance.” Says Doug. “These machines were being cleaned out and oil was replaced every 6 months or less. This used to take 4 – 6 hours each, but now takes 1 – 2 hours each. We also pump the filtered oil back in at the first cleanout and now replace the oil annually.”

Because they can use the oil longer, they no longer have to buy as much. When asked about savings, Doug commented that on the very first machine “It would be a little over $4,000.00 for that machine alone.” And by reusing the filtered oil on the first clean out of the 12 other machines they save another $6,000-$8,000 in oil purchases. And the time savings amounted to well over a 100 hundred hours per year.

What else does Doug like about the Sump Shark? “The ability to vacuum the chips up with the cutting oil saves a lot of time along with the fact that you can easily reverse this to pump oil back into the machine to get the chips loose that are stuck in hard to reach places.” No more removing pumps and conveyors. “These tanks are roughly 50 gallons each and the Sump Shark will fill them with filtered oil in just a couple of minutes.” adds Doug.
