FEDCO HP-HEMI 2000 Turbocharger Energy Recovery Device
Manufactured by Fluid Equipment Development Company (FEDCO), Monroe, Michigan, USA — supplied by ForeverPure Corporation, an authorized FEDCO distributor based in Santa Clara, California.
The FEDCO HP-HEMI is a motor-assisted hydraulic turbocharger ERD that combines an integral motor and VFD with the proven HPB rotor design. It allows the high-pressure feed pump to run at constant speed and pressure while the HP-HEMI itself provides feed-flow control and energy recovery — eliminating the need for a VFD on the main HP pump.
? Made to Order — Call for Availability
Each FEDCO energy recovery device is built to order at the FEDCO factory in Monroe, Michigan, sized to the customer's specific duty point (flow, pressure, feed TDS, recovery, materials of construction).
Typical lead time: 6–8 weeks (Super Duplex 2507) or 3–6 weeks (Duplex 2205). Call for current availability.

Theory of Operation
The HP-HEMI takes the high-pressure brine reject from the membrane train and uses its hydraulic energy to spin a turbine, which is mechanically coupled (through a single shaft) to a centrifugal pump impeller boosting the feed stream. An integral electric motor — sized only for the residual energy gap — adds shaft power as needed and is controlled by a VFD to set feed flow precisely. The result is a single rotating assembly that recovers brine pressure energy and provides flow control without the size, cost, and electrical losses of a full-size VFD on the main HP pump.
Key Engineering Advantages
- Eliminates the VFD on the main high-pressure pump
- Lowest specific energy consumption among turbocharger ERDs
- Lowest CAPEX among ERD classes for mega-scale trains
- Single-shaft hydraulic + electric energy recovery — no isobaric piston cycling
- Self-regulating, stable under feed-quality and temperature changes
Applications & Industries
Typical Applications
- Mega-scale Seawater Reverse Osmosis (SWRO)
- High-flow desalination trains where eliminating the main HP pump VFD reduces CAPEX and switchgear requirements
- Plants with constant feed-pump operation and turbocharger-based flow control
Industries Served
- Municipal desalination
- Industrial water reuse
- Marine / offshore
Sizing & Selection
Model number convention: roughly correlates to flow capacity in m³/h. Best efficiency is typically achieved within ±20% of nominal flow — for duty points outside this range, consult ForeverPure to confirm the correct frame size.

Frequently Asked Questions
What is the FEDCO HP-HEMI-2000?
The FEDCO HP-HEMI is a motor-assisted hydraulic turbocharger ERD that combines an integral motor and VFD with the proven HPB rotor design. It allows the high-pressure feed pump to run at constant speed and pressure while the HP-HEMI itself provides feed-flow control and energy recovery — eliminating the need for a VFD on the main HP pump.
What is the FEDCO HP-HEMI-2000 used for?
Typical applications include mega-scale seawater reverse osmosis (swro); high-flow desalination trains where eliminating the main hp pump vfd reduces capex and switchgear requirements; plants with constant feed-pump operation and turbocharger-based flow control. Industries served: municipal desalination, industrial water reuse, marine / offshore.
What materials of construction does the FEDCO HP-HEMI-2000 use?
Wetted parts are super duplex stainless steel 2507 (wetted parts standard), providing corrosion resistance suited to seawater and chloride-rich brackish-water service.
How does a FEDCO turbocharger ERD compare to an isobaric pressure exchanger (PX, iSave, APM)?
FEDCO turbocharger ERDs (HPB, HP-HEMI) recover brine pressure energy through a hydraulic turbine that directly boosts the feed stream — a single rotating assembly with no piston cycling and no brine-feed mixing. Isobaric pressure exchangers (Energy Recovery Inc. PX, Danfoss iSave, Danfoss APM) instead transfer pressure through ceramic rotors or pistons between brine and feed streams. Turbochargers are mechanically simpler, have zero brine-to-feed mixing, are well-suited to small-to-medium SWRO and packaged plants, and FEDCO's HPB demonstrates 83%+ transfer efficiency in the field.
Where can I get the FEDCO HP-HEMI-2000 datasheet, performance curve, and pricing?
