LPH Energy Recovery Motorized Turbocharger

The LPH series pumps integrate pump and turbine modules for a motorized turbocharger energy recovery device and interstage booster.

  • Pressures up to 35 bar
  • Feed flow up to 750 m3/h (3300 gpm)
  • Brine flow up to 300 m3/h (1320 gpm)
  • 316 SS or better
  • Modular design – up to 3 pumps in parallel on one motor and energy recovery turbine

The LPH is revolutionizing pumping and energy recovery in brackish water reverse osmosis (BWRO). The rapid acceptance is driven by simple economics – an ERD is only worth using if the cost of saved energy can offset the capital and installation cost of the ERD (a quick return on investment or ROI).

The unique modular construction of the FEDCO LP product line allows a few components to be configured in dozens of ways to achieve the performance requirements of a wide range of BWRO systems without high capital and installation costs. Maintenance costs are likewise reduced as a maintenance spare and procedures are minimized for large installations.

Modular design reduces costs and increases application flexibility

  1. Motor
  2. Brine discharge module
  3. Turbine module
  4. Brine flow nozzle control
  5. Thrust bearing, patented design — water lubricated
  6. Manifold (if more than one pump module) 316 SS construction, provided by FEDCO
  7. Pump module — up to three (3) depending on flow requirement
  8. All wetted metallic parts are 316 SS or better
  9. Pipe joint connectors

The LPH takes full advantage of the modular concept with two (2) turbine options, five (5) stage options and up to three (3) pump modules per LPH. Moreover, the turbine module is custom-designed and manufactured to match the specified range of turbine brine flow and pressure ranges.

  1.  TEFC motor, rated for vertical operation and with a VFD
  2.  Variable brine nozzle for flow and pressure control
  3.  316 SS or better material of construction
  4.  In-line connections for easy installation
  5.  Integrated water-lubricated bearing absorbs all rotor thrust
  6.  Base plate — powder coated or paint option
  7.  Victaulic type pipe joints
  8.  Turbine nozzle ring and impeller custom-manufactured
  9.  Rotatable turbine section for piping flexibility
