Eclipse Product Installed: Filtramag FM2.5
Industry: Automotive Components
Process Type: Fuel Tank Wash System
Permoid Industries Ltd produces several hundred diesel fuel and hydraulic tanks for Caterpillar earth moving vehicles each year to precise and demanding specifications. During the finishing process fuel tanks are inserted into a sealed flushing rig where wash solution is sprayed at pressure via rotating nozzles to both the interior and exterior of the tank. Water collects in a holding tank and is then pumped out to spray the next tank in the sequence. The water is at 60°C (140F) and pumped at approximately 4 to 6 bar (58 to 87 PSI)pressure. Before returning to the holding tank the wash solution passes through a paper barrier filter to remove contamination.
The paper filters only removed particles down to 5 micron size, this meant that smaller particles continued to be re-circulated in the process. The ferrous particles caused damage to the product surface and caused a build of ferrous debris within the tanks. As a result a high proportion of tanks failed the demanding inspection process. Permoid were issued an ultimatum from Caterpillar - to solve the problem or cease being a supplier. In addition to the quality problems there were operational problems such as barrier filters were being changed on a 4 weekly basis and pumps were failing prematurely due to damage from ferrous particles.
Filtramag FM2.5 units were fitted, one in the flow circuit prior to the re-circulating pump and one on the drain back to the holding tank. Since fitting Filtramag the ferrous contamination has greatly reduced to a point whereby finished product reject rates are virtually zero. Barrier filters remain fitted but only have to be changed every 10 months. An additional benefit is that the pump life was greatly improved as metal particles were no longer able to damage the pump internals.
High-performance magnetic filter for harsh environments (flow rates up to 500 litres per min.)
"We were delighted with the service provided by Eclipse Magnetics; from the initial site survey through to delivery."
"I cannot begin to tell you how much it has helped our operation, the magnetic filtration unit has been a real problem solver it has surpassed all our expectations. Its cured a 30 year plague!"
"This technology is economical, reliable and efficient. I believe that magnetic filtration technology is the future."
"Magnetic filtration has dramatically cleaned up our fluids and improved the surface finish we can offer. It extracts around 50Kg per day of ferrous waste."
"We chose Eclipse Magnetics to supply our housed grid because they are a respected and well-established brand. They offered us a very competitive price, and the process of ordering and installation was straightforward and reliable."
“We are delighted with the Automag installation; it’s solved all the problems we were having previously with downtime and maintenance costs. The filter means that we are able to use recycled water, which is saving us £1000 per week!”
"Here at Qualflow, we base our business on a philosophy of make the product simple to use, reliable and cost-effective. Eclipse Magnetics’ neodymium magnets offer the strongest magnetic performance, and are nickel plated, making them a cost effective.."
"The Ultralift Plus magnetic lifter from Eclipse Magnetics is the perfect solution for the pick-up and transportation of the ultrasonic calibration blocks in our facility"
"The result is an aesthetically pleasing system, which is effective in trapping metal contaminants and is easy to clean..."
