PRECAUTIONS
1
1.0 Precautions
The following precautions should be taken when working with LMI metering pumps.
Please read this section carefully prior to installation.
Protective Clothing
ALWAYS wear protective clothing, face shield, safety glasses and gloves when working on or
near your metering pump. Additional precautions should be taken depending on the solution
being pumped. Refer to Safety Data Sheets (SDS) precautions from your solution supplier.
Water Pre-Prime
All LMI pumps are pre-primed with water when shipped from the factory. If your solution is not
compatible with water, disassemble the Pump Head Assembly. Thoroughly dry the pump head,
valves, O-rings, balls and diaphragm. Reassemble head assembly tightening screws in a
crisscross pattern. Refill the pump head with the solution to be pumped before priming the
pump. (This will aid in priming.)
Liquid Compatibility
CAUTION: The evaluation performed by ETL was tested with water only. The pumps are
certified to NSF 61 with: sodium hypochlorite (12.5%), sulfuric acid (98.5%), sodium hydroxide
(50%), and hydrochloric acid (30%). Determine if the materials of construction included in the
liquid handling portion of your pump are adequate for the solution (chemical) to be pumped.
Always refer to the solution supplier and the Milton Roy Chemical Resistance Chart for
compatibility of your specific Milton Roy metering pump. Contact your local Milton Roy distributor
for further information.
Tubing Connections
Inlet and outlet tubing or pipe sizes must not be reduced. Outlet tubing size must not be
increased. Make certain that all tubing is SECURELY ATTACHED to fittings prior to start-up (see
section 3.3 Tubing Connections). ALWAYS use LMI supplied tubing with your pump, as the
tubing is specifically designed for use with the pump fittings. It is recommended that all tubing be
shielded and secure to prevent possible injury in case of rupture or accidental damage. If tubing
is exposed to sunlight, black UV resistant tubing should be installed. Check tubing frequently for
cracks and replace as necessary.
Fittings and Machine Threads
All fittings should be hand-tightened. An additional 1/8 - 1/4 turn after the fitting is snug may be
necessary to provide a leak-proof seal. Excessive overtightening or use of a pipe wrench can
cause damage to the fittings, seals, or pump head.
Most LMI pumps have straight screw machine threads on the head and fittings and are sealed
by the O-rings. DO NOT use PTFE tape or pipe dope to seal these threads. PTFE Tape may
only be used on NPT threads.
Plumbing
Always adhere to your local plumbing codes and requirements. Be sure installation does not
constitute a cross connection. Check local plumbing codes for guidelines. LMI is not responsible
for improper installations.

PRECAUTIONS
2
Back Pressure/Anti-Syphon Valve
If you are pumping downhill or into low or no system pressure, a backpressure /anti-syphon
device should be installed to prevent over pumping or syphoning. Contact your LMI distributor
for further information.
Electrical Connections
WARNING: To reduce the risk of electrical shock, the metering pump must be plugged into a
properly grounded grounding-type receptacle with ratings conforming to the data on the pump
control panel. The pump must be connected to a good ground. Do notu se ad apters!All wiring
must conform to local electrical codes. If the supply cord is damaged, it must be replaced by the
manufacturer, stocking distributor, or authorized repair center in order to avoid a hazard.
Fuse and Battery
CAUTION: Battery may explode if mistreated. Do not recharge, disassemble or dispose of in fire.
The battery and fuse are internal, factory serviceable parts, and must be replaced by the factory
or a qualified distributor with parts of the same type and rating.
Flooding
WARNING: Install this pump in a location where flooding cannot occur.
Ground Fault Circuit Interrupter
WARNING: To reduce the risk of electric shock, install only on a circuit protected by a Ground
Fault Circuit Interrupter (GFCI).
Line Depressurization
To reduce the risk of chemical splash during disassembly or maintenance, all installations
should be equipped with line depressurization capability.
Over Pressure Protection
To ensure safe operation of the pump it is recommended that some type of safety / pressure-
relief valve be installed to protect the piping and other system components from failing due to
excessive pressure.
Chemical Concentration
There is a potential for elevated chemical concentration during periods of no flow, for example,
during backwash in the system. Steps, such as turning the pump off, should be taken during
operation or installation to prevent this.
See your distributor about other external control options to help mitigate this risk.
Retightening Components
Plastic materials will typically exhibit creep characteristics when under pressure over a period of
time and to insure a proper fit it may be necessary to retighten the head bolts periodically. To
insure proper operation, we recommend tightening the bolts to 25 inch-pounds after the first
week of operation and on a monthly basis thereafter.

PRECAUTIONS
3
Flow Display
The accuracy of the flow value as shown on the pump display is highly dependent on the
specific application. Calibration is necessary in order to display an accurate measure of the flow.
Spills
CAUTION: Spills of Dangerous chemicals should be cleaned up immediately.

2.0 Introduction
LMI's metering pumps deliver the highest level of repetitive accuracy and reliability
with the capability to pump a wide range of chemicals. Our comprehensive selection
of pumps means you get the right pump for the right application. Every one of our
pumps is engineered to exceed expectations and is backed by a global network of
highly trained field engineers and aftersales support.
P lease review this manu alcarefu lly.P ay particu larattention to warnings and
precau tions. A lways follow good safety proced u res, inclu d ing the u se of
properclothing,eye and face protection.

3.0 Installation
3.1 Pump Location and Installation
Locate pump in an area convenient to solution tank and electrical supply.
The pump should be accessible for routine maintenance, and should not be operated
in ambient temperatures above 104°F (40°C). If the pump will be exposed to direct
sunlight, LMI black, UV resistant tubing should be installed.
3.2 Pump Mounting
The pump can be mounted in one of two ways:
Flooded Suction (ideal installation); or
Suction Lift - when suction lift is less than specified in section 2.1
Specifications and the fluid has a specific gravity of water and viscosity of
less than 50 cPs (centipoise). For denser or more viscous solutions, consult
distributor.
Note that suction conditions can affect the performance of the pump. This effect is
more pronounced with lower pressure pumps. Consult your distributor for additional
information.
Your LMI metering pump must be mounted so that the suction and discharge valves are
vertical.
NEVER position pu mphead and fittings horizontally.

INSTALLATION
7
3.2.1 Flooded Suction
For flooded suction, the pump is mounted at the base of the storage tank. This
installation is the most trouble-free, and is recommended for very low outputs,
solutions that gasify, and high-viscosity solutions. Since the suction tubing is filled
with solution, priming is accomplished quickly and the chance of losing prime is
reduced. A foot valve is not necessary in a flooded suction installation.
When pumping downhill or into a low or no pressure system, a backpressure / anti-
syphon device should be installed to prevent over pumping or syphoning.
Although popular for all solutions, LMI recommends flooded suction installations for
all high-viscosity fluid applications.
INCORRECT
Avoid this type of false flooded suction

INSTALLATION

3.3 Tubing Connections
Use only LMI supplied tubing with your pump, as the tubing is specifically designed
for use with the pump fittings. Before installation, all tubing must be cut with a clean
square end. Valve and head connections from the factory are capped or plugged to
