Certified test results confirm, FEDCO turbochargers are up to 10% more efficient. FEDCO is the foremost leader in the turbocharger efficiency with guaranteed performance and the only units with 80+% transfer efficiency. Our engineering and manufacturing teams have the most experience and most advanced test equipment for continuous efficiency improvements.

Standard HPB Product Line

With nine models, there is a perfect HPB for the most demanding project requirements. Standard MOC is Duplex SS 2205, however, customers also have the option to utilize Super Duplex SS 2507. Brine nozzle valve actuators and flanged connections are also available for the HPB. Each product is built to customer flow and pressure specifications, and delivery of a standard HPB is only three to six weeks!

  1. Variable area in nozzle (needle type for precise control)
  2. Nameplate  
  3. Thrust bearing - patent pending design, allows dry running
  4. Brine nozzle and volute - custom designed and machined
  5. Brine (turbine) impeller - custom designed and machined
  6. Rotor shaft - integral with impellers (no keys, studs, washers, etc.)
  7. Center bearing lubricated by feed - ZERO brine leakage to feed
  8. Feed (pump) impeller - custom designed and machined
  9. End cap
  10. Multi-vane diffuser - custom designed and machined to ensure radial pressure balance for long wearring and bearing life,  provides higher efficiency than volutes
  11. Mounting foot (varies by model)
  12. O-rings - all bearings mounted on o-rings for easy removal
  13. Victaulic-type pipe joints (flanged joint optional)
  14. Standard Duplex SS 2205 MOC (Super Duplex SS 2507 optional)
  15. Can discharge brine at higher pressure for easy brine disposal

Brine Flow Regulation

Brine flow adjustment is accomplished by simply turning the aux nozzle handle. Open to increase brine flow and close to reduce it; the multi-turn needle valve provides precise flow regulation. Brine is not bypassed when the nozzle is open - all brine flow passes through the turbine impeller to maximize energy recovery.

Efficiency

Whether is is field operation log sheet data or precision test stand data, the HPB displays the highest average efficiency of any turbocharger ERD. Fully-machined rotors, multi-vane diffusers, and CFD-optimized hydraulic design are what set the HPB apart.

Mega HPB Product Line

Six mega HPB models cover some of the largest SWRO trains on earth, including the HPB-1400s used in Jeddah III.  Standard MOC is Duplex SS 2205 with optional Super Duplex SS 2507; brine nozzle valve actuators and flanged connections are also available.

  1. Brine aux nozzle valve (needle type for precise control)
  2. Nameplate
  3. Thrust bearing — patent pending design, allows dry running
  4. Brine (turbine) impeller — custom designed and machined
  5. Rotor shaft — integral with impellers (hidden in this view)
  6. Center bearing — lubricated by feed, ZERO brine leakage to feed
  7. Feed (pump) impeller ‚ custom designed and machined
  8. End cap
  9. Multi-vane diffuser — customer designed and machined to ensure radial
    pressure balance for long wear ring and bearing life, provides higher efficiency than volutes
  10. Baseplate
  11. O-rings — all bearings mounted on o-rings for easy removal
  12. Cut groove type pipe joints (flanged joints optional)
  13. Standard Duplex SS 2205 MOC, optional Super Duplex SS 2507
  14. Can discharge brine at high pressure for easy brine disposal
  15. Integral brine passage for auxiliary turbine nozzle
  16. Hand wheel, optional valve actuator, for brine flow regulation

Hundreds of Tests, Years of Analysis

The mega HPB line is subjected to numerous CFD (Computational Fluid Dynamics) runs, which in turn involve trillions of calculations to optimize every inch of the flow passages.

Proprietary softward converts the CFD designs into CNC (Computer Numerical Control) programs to turn the Duplex SS / Super Duplex SS plates into ultra-smooth, hydraulically-optimal feed and brine channels, while special bearing systems ensure reliable operation with minimal bearing losses.
