SAFETY INSTRUCTIONS
READ ALL INSTRUCTIONS PRIOR TO USE
Secure chemicals & metering pumps, making them inaccessible to children & pets.
*** DO NOT PUMP FLAMMABLE LIQUIDS.
*** Do not cut the plug or ground lug off the electrical cord. Consult a licensed electrician for proper installation or
replacement.
To reduce the risk of electrical shock-before maintenance, repair, or moving, always disconnect the power
to the pump by unplugging from wall outlet.
Always wear protective clothing, including gloves and safety glasses, when working on or near chemical
metering pumps.
** Inspect tubing regularly for cracking or deterioration and replace as necessary. (Always wear protective clothing and
safety glasses when inspecting tubing.)
** Use CAUTION to keep fingers away from rotating parts.
** If pump is exposed to direct sunlight, use a UV resistant tubing.
** Follow directions and warnings provided from the chemical manufacturer. The user is responsible for determining the
chemical compatibility with the chemical feed pump.
** Make sure the voltage on the pump name tag matches the installation voltage. If pump fails to start, check line voltage.
** Consult with local health officials and/or qualified water conditioning specialists when treating potable water.
** Always depressurize system prior to installation or disconnecting the metering pump tubing.
** If injection point is lower than the chemical tank and pump, install an anti-siphon valve.
** DO NOT MODIFY PUMP. This poses a potentially dangerous situation and will void the warranty. Hand tighten plastic
connections (Do not use wrench).
All pumps are factory tested with water. Remove tubing and thoroughly dry if the chemical being pumped
will react with water (for example sulfuric acid).
* Hand tighten plastic connections (Do not use wrench).
* Consult licensed plumber and electrician before installation to conform to local codes.
* NOTE: For accurate volume output, pump must be calibrated under all operating conditions.
INTRODUCTION
Series 100/150 are diaphragm-type metering pumps. A fluid is pumped from a
chemical storage tank to the point of injection by the pulsing action of the
diaphragm. The four check valves (top and bottom of pump head, strainer
assembly, and injection assembly) keep the fluid flowing toward the point of
discharge. To insure the solution being pumped can only go forward, it is
important that all check valves provide positive, non-leaking backflow
prevention. The wetted end (those parts that contact the solution being
pumped) is constructed of SAN, PVC, TFE, Hypalon®, and polyethylene.
These materials are very resistant to most chemicals. However, there are
some chemicals, such as strong acids or organic solvents, which cause deterioration of some elastomer and plastic parts,
such as diaphragm, valve seat, or head. Alternate materials such as Viton®, polypropylene is available on request.
Contact chemical supplier for chemical compatible materials.

MANUFACTURER’S PRODUCT WARRANTY
The manufacturer warrants its equipment of its manufacture to be free of defects in material or workmanship. Liability
under this policy extends for twenty-four (24) months from the date of purchase or one (1) year from date of installation or
whichever comes first. The manufacturer’s liability is limited to repair or replacement of any device or part which is
returned, prepaid, to the factory and which is proven defective upon examination. This warranty does not include
installation or repair cost and in no event shall the manufacturer’s liability exceed its selling price of such part.
The manufacturer disclaims all liability for damage to its products through improper installation, maintenance, use or
attempts to operate such products beyond their functional capacity, intentionally or otherwise, or any unauthorized repair.
Replaceable elastomeric parts are expendable and are not covered by any warranty either expressed or implied. The
manufacturer is not responsible for consequential or other damages, injuries or expense incurred through use of its
products.
The above warranty is in lieu of any other warranty, either expressed or implied. The manufacturer makes no warranty of
fitness or merchantability. No agent of ours is authorized to make any warranty other than the above.

PRECAUTIONS FOR OPERATION
Each Series 100/150 chemical feeder has been tested to meet prescribed specifications and certain safety standards.
However, a few precautionary notes should be adhered to at all times. THOROUGHLY READ ALL CAUTIONS PRIOR TO
INSTALLING METERING PUMP.
1. Chemicals used may be dangerous and should be used carefully and according to warnings on the label. Follow
the directions given with each type of chemical. Do not assume chemicals are the same because they look alike.
Always store chemicals in a safe location away from children and others. We cannot be responsible for the
misuse of chemicals being fed by the pump.
2. Always wear protective clothing (protective gloves and safety glasses) when working on or near chemical
metering pumps.
3. Tampering with electrical devices can be potentially hazardous. Always place chemicals and feeder installation
well out of the reach of children and others.
4. Be careful to check that the voltage of the installation matches the voltage indicated on the specification label.
Each pump is equipped with a three prong plug. Whether plugging into a receptacle or wiring into a system,
always be sure the feeder is grounded. If receptacle is utilized, to disconnect, do not pull wire but grip the plug
with fingers and pull out.
5. Never repair or move the metering pump while operating. Always disconnect electrical current. Before handling
the pump always allow sufficient time for the motor housing to cool off. Handling the pump too soon after
shutdown may cause hand burns. For safety use protective gloves.
6. All pumps are pretested with water before shipment. Remove head and dry thoroughly if you are pumping a
material that will react with water, (e.g. sulfuric acid). Valve seats, ball checks, gaskets, and diaphragm should
also be dried. Before placing feeder into service, extreme care should be taken to follow this procedure.
7. Arrows on the pump head and injection fitting indicate chemical flow. When properly installed, these arrows
should be pointing upward.
8. When metering hazardous material DO NOT use plastic tubing. Strictly use proper rigid pipe. Consult supplier for
special adaptors.
9. Pump is NOT to be used to handle or meter flammable liquids or materials.

10. Standard white polyethylene discharge tubing is not recommended for installations exposed to direct sunlight.
Consult supplier for special black polyethylene tubing.
11. Manufacturer will not be held responsible for improper installation of pumps, or local plumbing conducted. All
cautions are to be read thoroughly prior to hook-up and plumbing. For all installations a professional plumber
should be consulted. Always adhere to local plumbing codes and requirements.
12. Note the maximum pressure rating of the metering pump. When used with pressurized systems, always be sure
the pressure of the system does not exceed maximum pressure rating listed on the specification label.
13. Be sure to depressurize system prior to hook-up or disconnection of metering pump.
INSTALLATION, PIPING AND WIRING
UNPACKING, ASSEMBLING AND MOUNTING:
The carton should contain:
Metering Pump
4 ft. (1.21 m) Clear Flexible Suction Tubing
4 ft (1.21 m) Stiff White Return Tubing
Feeder can be mounted on a wall shelf bracket
(Figure B), tank stand platform (Figure C),
directly on the wall (Figure D), or directly on the
tank cover (Figure E).
Bleed Valve Assembly
Instructions
Strainer Assembly w/Tube Weight
Back Check Valve Assembly
8 ft (2.43 m) Stiff White Discharge Tubing
(Optional black tubing for UV protection
available from the factory)
To mount the feeder directly on the wall, place the feeder base against the wall with the motor below the pumping head,
remove four head mounting bolts, and turn head quarter turn so suction is in bottom position.
IMPORTANT: Injection point must be higher than top of solution tank to prohibit gravity feeding. Maximum head
in meters is 70m/H2O for Series 100 Model pumps and 42m/H2O for Series 150 Model pumps.
NOTE: Make sure the arrow on the outside of the pump head is pointing upward. The pump must be positioned
so that the plug is accessible.
