Sump Cleaner Helps Regal Machine Recycle Coolant-Image

Challenge: Cut time needed to clean machine tool sumps and extend the life of coolant.

With over 50 machine tools, cleaning machine sumps was a time-consuming job for the staff of Regal Machine in Wyoming, MN. They used an air pump and a 55-gallon drum to empty the sumps and then cleaned up the chips and fines manually. Because it was a messy, unpleasant job, it wasn't being done often enough. Chips and swarf in the coolant caused bacteria to grow. The coolant was not recycled, but hauled off by a service and new coolant was put in the machines.


Last May, Regal Machine added an SE50-175PT Sump Shark sump cleaner to the plant line-up. The SE50 extra-power unit pumps up to 110 gallons per minute. Don Eberhardt, the shop foreman, sums up the change. "Now we can filter the coolant and replace it in about 15 minutes average. Before it took hours and we did not recycle". With a suction lift of 13 Hg, the Sump Shark sucks coolant, chips and sludge from the machine tool sump. As it enters the tank it passes through a 5 cu.ft. filter where the solids are trapped. The filtered coolant accumulates in the tank. Then the filtered coolant is pumped back into the machine for reuse.

Regal Machine has implemented a coolant maintenance schedule and machine sumps are routinely cleaned every six months. Using the Sump Shark "I've run the machine myself and what I like is the ease and convenience. It's easy to run. It's made my life a lot easier." says Don. In fact, Regal Machine has not had to change out their coolant since they started using the Sump Shark, so it would be difficult to say how long coolant life has been extended, but if Don had to guess he would say "double".
