operates the largest pump and ERD test system dedi-
cated to SWRO systems in the world.
Our teams of talented and energetic engineers,
manufacturing specialists and systems experts have
created a fully integrated enterprise with one aim – to
provide our customers with customized uid machines
with exceptional e󰀩ciency and low capital cost cou-
pled with customer service that exceeds their expec-
tations. The results include new designs, technology,
manufacturing processes, and standards. Our pumps
and ERDs use bearings that are lubricated by feed or
brine to eliminate the numerous maintenance and lo-
gistics issues associated with oil or grease lubricated
bearing systems. We o󰀨er three materials of construc-
tion: Duplex SS, Super Duplex SS and 316 SS.
We design uid machines to take full advantage of the
technical characteristics of the membrane process.
FEDCO pumps only cover ows and pressures found
in BWRO and seawater SWRO applications. They are
designed for clean uids and are optimized for typical
suction pressures in RO systems. Our ERDs include
variable area nozzles that meet typical brine pressure
variations. Our products eliminate external tubing car-
rying high pressure feed or brine that can fail creating
hazards to personnel and equipment. Our units are
designed for operation and maintenance by unskilled
personnel in the harshest of desert or marine environ-
ments.
With the longest warranty and the highest e󰀩ciencies,
our product lines are unmatched in quality and per-
formance by any manufacturer in the RO equipment
market. FEDCO is a widely recognized supplier with
thousands of units installed around the world.

Theory and Operation
HPB External Components
The Hydraulic Pressure Booster™ or HPB™ is designed to provide brine energy recovery in
reverse osmosis (RO) systems. The HPB™ is energized by the high-pressure brine stream which
causes the HPB™ to generate a large pressure boost in the feed stream independent of the high
pressure feed pump.
The HPB™ is typically installed between the
high pressure feed pump and the membrane.
The feed passes through the pretreatment
system and then passes through the feed
pump which raises the feed pressure. The
pressurized feed passes through the HPB™,
which provides an additional pressure increase
before passing to the membrane. The high
pressure brine steam from the membrane is
directed back to the HPB™.
The HPB™ recovers the pressure energy and
discharges the brine at low pressure for dis-
posal. The HPB™ does not require a brine
disposal pump or gravity ow piping as the
brine can be discharged against a back pres-
sure. The HPB™ reduces feed pump energy
consumption and allows use of a smaller feed
pump, smaller motor, smaller motor starter,
electrical wiring, etc.
