INTRODUCTION TO CEM TECHNOLOGY

In the field of pump technology, it is not often that the adjectives "simple" and "state-of-the-art" can be applied to the same design. The need for higher pump efficiencies prompted Eddie Paul to explore the possibilities of a product that qualified on both counts. The CEM is the revolutionary pump, compressor, or engine that resulted from 16 years' research in the field of positive displacement technology. In 1993, the CEM received its first patent as an engine, pump, and compressor by the U.S. Patent Office. It has since been patented in the rest of the world and received its latest improvement patent in 2000.

The CEM's uniqueness lies in its simplicity of design. Its main design feature is compactness. We have managed to fit 12 cylinders into a unit that's smaller than many one-cylinder engines designed by other companies. Its weight is about one-sixth that of an equal-capacity unit and its cost of production is less than its competitors'. The CEM can produce either low or high pressure and can be run as a single unit or staged within itself to multiply either volume or pressure.

Another outstanding feature is that its output is 24 times that of most pumps or compressors of equal bore and stroke, and twice that of most engines. This is because the CEM is configured axially and features a mirror image arrangement of six dual-headed pistons. With a pumping event occurring simultaneously at either end of the rotating cylinder, each piston completes four cycles - two at each end - per cylinder revolution for a total of 24 pumping cycles per revolution.

And all of this is accomplished with only seven internal moving parts! With fewer parts there are fewer problems, less engineering, lower manufacturing costs, fewer parts to inventory, and greater reliability. The CEM is scalable and can be manufactured to meet any dimension or output requirement from a variety of materials to maintain compatibility with any fluid medium. The pump is self-priming and virtually maintenance free. The CEM's internal components can be machined from advanced thermoplastic-based resins with ultra-low friction characteristics.

Since its introduction, the diversity and number of applications for CEM technology has increased tremendously. Our CEM Company supplies laser-cooling pumps to major aerospace companies as well as products for other large corporations in the automotive, industrial, and environmental fields.

THE CEM ENGINE

The CEM Engine is being developed by E.P. Industries. The CEM Engine will be an efficient method of converting fuel energy into electrical energy. E.P. Industries is now offering interested parties an opportunity to purchase a license for this technology. Please contact eddiepaul@epindustries.com with licensing inquiries.

The CEM Engine will be capable of delivering substantially greater performance with greatly reduced manufacturing cost. A novel concept for significantly increasing the efficiency of the four-stroke cycle internal combustion engine, the Department of Defense in 1997 awarded the engine concept an SBIR. The super-charged CEM Engine has the potential to become one of the first self-lubricating, air-cooled, multi-fuel, four-stroke cycle engines to deliver two horsepower/pound.


EXCLUSIVE TO THE CEM PUMP

* The CEM is a positive-displacement piston pump utilizing rotary cylinders to increase mechanical efficiencies far above normal piston pumps.
* The CEM can be manufactured at far less cost compared to normal piston pumps.
* The CEM is simple in design and function. It pulls fluid or air through one port and pushes it out the next port. There are no valves, valve plates, gears, piston rings, wrist pins, crankshaft, connecting rods, flywheel, or lubricating system.
* The CEM is 80% to 90% efficient.
* The CEM is a compact pump that takes up less space than any other positive-displacement piston pump in the world of equal output (flow volume).
* The CEM’s primary advantage is being able to produce 24 complete (fluid in, fluid out) pump cycles in one revolution of the driveshaft. A standard piston pump produces only one complete pump cycle per revolution.
* The CEM is lighter by up to 50% than any other positive-displacement pump of equal output.
* The CEM will pump fluid and/or air in either direction and is self priming.
* Can be manufactured from a variety of plastics that reduce overall weight


Here's what industry experts say about CEM

"As a liquid pump, it is ideal...This design obviously has massive potential because of its flexibility."
