Commitment to Quality & Success

Fluid Equipment Development Company (FEDCO)

was founded in 1997 to develop new uid machinery

to reduce the cost of reverse osmosis desalination.

The results included patented concepts, highly in-

tegrated design, superior production software, and

sophisticated manufacturing processes. Our e󰀨orts

culminated in multiple lines of energy recovery tur-

bines and pumps uniquely suited for seawater and

brackish RO desalination.

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 envi-

ronments. Additionally, our Monroe facility operates

the largest pump and ERD test system dedicated to

SWRO systems in the world.

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.

Warnings and Safety Precautions

Continued

WARNING

All pump and safety precautions must be followed

to prevent physical injury to the operator. It is illegal

to operate the equipment in an EU member state if

the manual(s) is not written in that state’s language.

Contact FEDCO if a translated copy is needed.

CAUTION

A pump is a pressure-generating device with rotating

parts that can be hazardous. Any device containing

generated pressure can rupture, explode or dis-

charge its contents if it is over-pressurized and may

possibly result in personal injury, property damage,

environmental damage and death. All necessary

precautions must be exercised to insure over-pres-

surization does not occur. FEDCO will not accept

responsibility for physical injury, damage or delays

caused by a failure to observe the instructions in this

manual.

WARNING

Installation, operation or maintenance of the pump

unit in any manner which is not covered in this

manual could cause damage to the equipment, seri-

ous injury or death. This includes any modication

to the equipment or the use of parts not provided by

FEDCO. If there is a question regarding the intend-

ed use of the equipment, please contact a FEDCO

representative before proceeding.

CAUTION

This manual clearly identies accepted methods for

safe disassembly and assembly. These methods

must be strictly adhered to.

WARNING

Do not use the pump equipment for a di󰀨erent appli-

cation than originally specied without the approval

of a FEDCO representative.

WARNING

NEVER operate the pump equipment:

● below the minimum ow rate.

● when dry.

● without priming.

● without proper guards and safety devices installed.

● with the discharge valve closed.

● with the suction valve closed.

WARNING

FEDCO pumps are intended to pump saltwater and

brine to membranes for the reverse osmosis desali-

nation process. FEDCO pumps are not intended

to pump ammable or hazardous liquids. Solutions

intended for human consumption need proper

purication per product. FEDCO approval will be

needed to control slurry and particle size for this

specic product

ELECTRICAL HAZARD

Always follow the Lock-out / Tag-out procedure

developed by your company before starting any

maintenance or repair.

User Health and Safety

Safety equipment and PPE (Personal Protection

Equipment) should be used in accordance with

company regulations.

In the Work Area

• Always keep the work area clean and dry.

• Avoid all electrical dangers. Be aware of risks

from electric shock or arc ash hazards.

• Utilize adequate lifting equipment and methods.

Electrical Connections and Regulations

• Refer to the motor nameplate for specic

electrical operating information.

• Electrical connections must be made by

certied electricians in compliance with

all international, national, state, and local

regulations and codes.

• Insure the product is isolated from the power

supply and cannot be accidentally energized.

• Make sure all thermal contacts are connected

to a protection circuit according to product

specications.

• You must ground (earth) all electrical

equipment. This applies to the pump

equipment, the driver, and any monitoring

equipment. Providing acceptable grounding

reduces risk of electric shock and stray currents

suspected of causing galvanic corrosion.
