  1. STELTH OPERATING PRINCIPLE AND MANUFACTURING RATIONALE

  2. STELTH,THE WORLDSLOWESTMANUFACTURING AND RUNNINGCOSTPUMP VERSE THE DAB PUMP, MODEL K14/400 M, 2.5 HP. DABIS FOR GENERAL PUMPING AND IS SOLD WORLDWIDE. HOW IS THIS DONE?

  3. NEW FLUID TECHNOLOGY HAS ALREADY HAD PUMPS MANUFACTURED IN CHINA !

  4. SIMPLE DIAGRAM SHOWS HOW THE “STELTH” WATER VORTEX MAKES THIS PUMP SO DIFFERENT

  5. HIGH EFFICIENCY AND LOW NOISE IS NEEDED NOW! • GOVERNMENTS ARE LEGISLATINGNOW OVER ENERGY EFFICIENCY OF SWIMMING POOL PUMPS. • AUSTRALIA HAS INTRODUCED ENERGY EFFICIENCY STARS ON POOL AND SPA PUMPS TAKING EFFECT IN OCTOBER 2011. • CALIFORNIA NOW REQUIRES TWO OR MORE SPEED POOL PUMPS AND OTHER U.S. STATES ARE READY TO FOLLOW.

  6. AUSTRALIA’S ENERGY STARS AND NOISE (dBA) LEGALLY REQUIRED FROM OCTOBER THIS YEAR • ONLY STELTH WILL BE AWARDED 9 STARS • MOST PUMPS WILL GET 7 STARS. • A PUMP OF 9 STARS IS 56% MORE EFFICIENT THAN ONE OF 7 STARS (IT COSTS 56% LESS MONEY TO RUN)

  7. THE MAIN PUMPING PROBLEM FOR THE WORLD! • LEGISLATION GIVES PUMP MANUFACTURERS A PROBLEM! • THEY HAVE ONLY THE CONVENTIONAL OLD TECHNOLOGY “WET END” FOR A PUMP. • THEY MUST EMPLOY HIGH EFFICIENCY, VARIABLE OR MULTI SPEED BLDC MOTORS TO LIFT PERFORMANCE. • BUT ONLY A REAL BREAKTHROUGH IN THE PUMP “WET END” WILL MAKE ONE BRAND STAND ABOVE THE REST AND REDUCE COST OF PUMPING WORLDWIDE.

  8. WHAT ARE THE MAIN BENEFITS OF THE STELTH “BREAKTHROUGH”? • LOW COST TO RUN • LOW COST MANUFACTURING • VERY LOW NOISE • SIMPLE FIELD SERVICING

  9. WHAT CHARACTERISTICS ARE NEEDED?HIGH EFFICIENCY AT: • HIGH SPEED • MEDIUM SPEED • VERY LOW SPEED • IN CHANGING SYSTEM RESISTANCE (FILTERS OR AUTOMOTIVE COOLING)

  10. THE BREAKTHROUGH HAS BEEN MADE. THE “LITERS PER KILOWATT HOUR” OF THE STELTH OVER MAJOR BRAND PUMP AT LOW SPEED OF 600 RPM.

  11. CHART BELOW SHOWS ABOUT 57% MORE LITERS PER KW/HR AT 20kpa FOR THE STELTH AND AT 15 kpa ABOUT 42% MORE THAN THE MAJOR BRAND PUMP • DATA FROM MANUFACTURERS OWN TEST STAND IN USA

  12. 1440 RPM IS HALF SPEED FOR A TWO SPEED PUMP AT 50 CYCLES. CALIFORNIA LEGISLATES 2 OR MORE SPEEDS FOR POOL PUMPS. AT 40 kpa STELTH PUMPS 23% MORE LITERS PER KW/HR THAN MAJOR BRAND PUMP AND AT 30 kpa PUMPS 14.7% MORE. • DATA FROM MAJOR BRAND`S OWN TEST STAND IN USA

  13. STELTH ADVANTAGE OVER PENTAIR “INTELLIFLOW”.

  14. Osbourne Reynolds (Reynolds Number), with respect to vortex rings, once remarked that nature preferred rolling over gliding. “Vortex Flow In Nature and Technology” page 91 Hans Lugt 1995.

  15. VORTICITY IS ONE OF THE ENERGY CONSERVATION LAWS • FEYNMAN AND LANDAU ESTABLISHED THAT ONLY MAN MADE SUPERFLUID HELIUM - 4 BELOW 2.1 DEGREE KELVIN IS IRROTATIONAL. • OTHERWISE EVERYTHING IS ROTATIONAL, ELECTRONS TO GALAXIES! • OUR PUMP IMPELLER SPINS THE WATER WITHIN A CIRCULAR PUMP CASE REDUCING LOSSES. • WE ELIMINATE THE DIFFUSING PASSAGES ESSENTIAL FOR CONVENTIONAL PUMPS TO GENERATE THEIR STATIC PRESSURE.

  16. NEW FLUID HAS MANY YEARS EXPERIENCE GENERATING VORTICITY FOR INDUSTRIAL AND ENTERTAINMENT APPLICATIONS. CLICK

  17. HOW “SOLID BODY” VORTICITY WORKS IN THE STELTH PUMP. • RED ARROW SHOWS ROTATIONAL DIRECTION OF THE IMPELLER AND WATER. • LARGE DIAMETER DRUM (SPIGOT), INTEGRAL WITH THE IMPELLER, DRAGS WATER AROUND ALONG WITH IMPELLER SURFACES AND IMPELLER TANGENTIAL WATER INJECTION. SOLID BODY MEANS WATER GOES FASTER HERETHAN HERE Isaac Newton described how a rotating parallel sided bucket induced water to spin up to the rpm of the bucket.

  18. SNAP IN INSERTS CHANGE PUMPING CAPACITY 2 HP 1.5 HP 1 HP ¾ HP

  19. IN A “SOLID BODY VORTEX” ALL THE WATER MOLECULES LINE UP LIKE WHEEL SPOKES AS WELL AS IN THE AXIAL DIRECTION. DIAGRAMS FROM “VORTEX FLOW IN NATURE AND TECHNOLOGY” HANS LUGT, 1995 NO SOLID BODY VORTEX CAN FORM IN THIS CHAMBER

  20. TWO KINDS OF VORTICITY • NEGATIVE PRESSURE VORTICES IN CIRCULAR CONTAINERS RESULT IN SAME MOLECULAR SPEED (MOLECULES SHEAR AS IN DYSON BAGLESS VAC). • POSITIVEPRESSURE VORTICES IN CIRCULAR CONTAINERS RESULT IN DIFFERENT MOLECULE SPEED (NO SHEAR AS IN STELTH). THIS IMPORTANT DISTINCTION BETWEEN THE KINDS OF VORTICES HAS NOT BEEN UNDERSTOOD BY MANUFACTURERS OF “VORTEX” PUMPS! SEE NEXT SLIDE FOR THIS

  21. EXISTING CONVENTIONAL “VORTEX” PUMPS • CHAMBER INTERNAL CORNERS ARE NOT SQUARE SO NO SOLID BODY VORTEX CAN FORM. • IMPELLER IS RECESSED ANDNO WATER IS INTRODUCED BY THE IMPELLER. • THESE PUMP SUSPENDED SOLIDS AND ARE OF LOW EFFICIENCY. IMPELLER INLET

  22. ITT IS THE WORLDS LARGEST PUMP COMPANY.ITT TEST RESULTS: STELTH V RULE MATE 2000 BILGE PUMP

  23. A HIGHER PRESSURE VERSION OF THE STELTH V RULE “MATE 2000”

  24. BELOW IS THE ITT RULE “MATE” 2000 BILGE PUMP AND THE STELTH BILGE PUMP. THE STELTH HAS RECENTLY BEEN REDUCED FURTHER IN HEIGHT:SEE NEXT SLIDE

  25. THIS LATEST SMALLER STELTH IS FOR AUTOMOTIVE ENGINE COOLING AND FOR BILGE PUMPS. IT IS VERY EASY TO MANUFACTURE

  26. THIS CHART PRODUCED BY THE UNIVERSITY OF ADELAIDE, AUSTRALIA.THEIR TEST RIG MEASURES ONLY THE EFFICIENCY OF THE PUMP AND NOT THE PUMP/MOTOR COMBINATION. A TORQUE TRANSDUCER MEASURES SHAFT POWER ONLY

  27. 3,500 RPM BELOW. NEXT TESTS WITH THE SMALLER STELTH, UP TO 8,000 RPM

  28. ITT ALSO TESTED BACK TO BACK THE DAVIES CRAIG EWP 115AUTOMOTIVE ENGINE COOLING PUMP AGAINST THE SMALLER A VERSIONSTELTH. TARGET

  29. STELTH PERFORMANCE SUMMARY • THE WATER VORTEX PERIPHERY GOES FASTER THAN THE IMPELLER PERIPHERY AND CONCENTRATES THE PRESSURE THERE. • MUCH QUIETER--- NO WATER WAKE COLLISIONS--- NO DIFFUSERS. • THE JETFANELECTRIC MOTOR COOLING FAN REDUCES NOISE EVEN FURTHER.

  30. WHY IS THE STELTH MUCH QUIETER? • SIMPLY BECAUSE IT HAS NO DIFFUSER. • POOL PUMPs ARE 62 dBA to 82dBA. 78dBA IS AVERAGE 330 LITERS/MINUTE • STELTH CAN PUMP 540 LITERS PER MIN AT 2880 RPM FOR A NOISE LEVEL OF 52.8 dBA. • NOISE LEVEL IS DOUBLED EACH 3 dBA!

  31. SIMPLE IMPELLER ASSEMBLY ELIMINATES ONE MANUFACTURING STEP AND ULTRASONIC WELDING SECURING BOLT NO ULTRASONIC WELDING MOTOR SHAFT

  32. THE STELTH HAS NO DIFFUSER • THE STELTH IMPELLER BACK IS THE SAME FOR ALL MODELS. ONLY THE IMPELLER CAP WITH DIFFERENT BLADE LENGTHS IS CHANGED TO VARY THE PASSAGE WIDTH. CHANGE ONLY CAPS DON’T CHANGE BACKS NARROW BLADE IMPELLER WIDE BLADE IMPELLER

  33. NO LABYRINTH SEAL (EASIER MANUFACTURING TOLERANCES) NO LABYRINTH SEAL NEGATIVE PRESSURE HERE

  34. NO EXPENSIVE MEHANICAL SEAL

  35. LOW COST O RING SHAFT SEAL?

  36. INTEGRATED WITH LEAF BASKET

  37. Whats does NFT`s future hold? • HYDROXYL RADICALS NFT is currently close to proving up the technology to • Sterilise water without the need for chemicals! Imagine pools/spas and municipal water without salt or chlorine. The inherent natural ability of tailored SS Pumps to produce large qtys of Hydroxyl radicals is the key.

  38. MULTIPLE APPLICATIONS • INDUSTRIAL • AGRICULTURE / RURAL • AUTOMOTIVE INCLUDING AERONAUTICAL • AEROSPACE • MARINE: BILGE PUMPS AND GENERAL PUMPING • POOLS / SPAS • SMALL, LIGHTWEIGHT • MILITARY, VERY QUIET WITH HIGH EFFICIENCY (USE LESS FUEL / ELECTRICITY)

  39. VERSION OF STELTH WITH COOLING AIR DUCTED AROUND THE MOTOR
