PART I - PRECAUTIONS
The following precautions should be considered while using the dosing pumps from MILTON
ROY EUROPE range. Please read carefully this section before performing the installation.
Protective clothing
ALWAYS wear protective clothing, mask for the face, protective glasses and gloves
while using or working next to the dosing pump. Some additional precautions should
be taken in conformity with the nature of liquid being pumped. Please refer to the
precaution of the MSDS provided with the liquid.
Water pre-priming
All the pumps are pre-primed with water at the factory. If the liquid to be pumped is not
compatible with water, dismantle the liquid end of the pump. Dry up completely the
liquid end, the check valves and the balls. Reassemble the liquid end by tightening
the screws in a diagonal pattern. Fill the liquid end with the liquid to be pumped
before priming the pump. (It will ease the start-up.)
Chemical compatibility
Check that the material of the liquid end is (chemically ) compatible with the liquid to
be pumped. Always refer to the liquid provider and to Chemical Resistance Chart for
compatibility with your pump. Contact your local distributor for additional information.
Piping connection
The suction and discharge piping connection and the piping size should not be
reduced. The size of the discharge piping should not be increased. Ensure that the
piping is FIRMLY FIXED before use. ALWAYS use piping provided with the pump, it
is specially designed for use with the pump connections. All piping should be
protected and attached to avoid possible damage in case of any breakage or
accidental damages. If the piping is exposed to the sun, a black UV protective piping
should be considered. Check regularly the piping for cracks and replace portions when
required.
Connectors
All connectors shall be tightened by hand. An additional turn of 1/8 to 1/4 of 360°
might be necessary to ensure tightness. Any excessive tightening or using a tool
might damage the connecting device and the seals or the liquid end.
All the GTM series pumps are tightened with o-ring seals. NEVER use Teflon® tape
or a sealing compound to seal the joints. The Teflon® tape can be used on injection
nozzles on the 1/2” NPT side, on the connection of stainless steel liquid end, or
directly on suction or discharge piping.

7
Installation
Always comply with local regulations and requirements. Ensure that the installation is
not obstructed. Comply with local piping regulations. Milton Roy Europe is not
responsible of the pump installation.
Back pressure valve / Anti-syphon valve
If you are pumping downhill or into low or no pressure system, a back
pressure/antisiphon device such as Four-Function Valve should be installed to
prevent over pumping or siphoning. Contact your distributor for further information.
Electrical installation
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 nameplate. The pump must be connected to a good ground.
Do not use adapters! 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.
Line Depressurization
To reduce the risk of chemical splash during disassembly or maintenance, all
installations should be equipped with line depressurization capability. Using Four-
Function Valve (-FV) is one way to include this feature.
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).
Clean less
The pump should be clean and dust should be wiped off.
Weight
If the weight of the pump is over 25Kg use adequate means to manipulate/transport it.

III - 2. HYDRAULIC INSTALLATION
For information on hydraulic installation of a dosing pump, refer to the "Advice sheets" of the
CD ROM provided with the pump. The main points are briefly described below.
III - 2.1 GENERAL (See figure 2.1b)
There must be no swan-necks or stagnant volumes which are liable to trap air or gast
Stresses due to incorrect alignment of piping with respect to the centreline of valves must
be avoided as far as possible.
•Remove burrs and clean the piping before fitting.
•It is advisable to provide for a calibrating chamber in order to calibrate the pump in
service conditions.
III - 2.2 PIPING ON THE SUCTION CIRCUIT (See figure 2.1b)
•If your pump is flooded, a shutt-off valve will be required (F 2.1d).
•If your pump is not flooded (suction lift), install the foot valve equipped with the filter
upstream of the above-mentioned item(F 2.1c)
•For viscous products: consult us.
•Install the pump as near as possible to the suction tank.
III - 2.3 PIPING ON THE DISCHARGE CIRCUIT (See figure 2.1d)
•Provide for a safety valve on the discharge pipe, designed to protect the installation.
•It is advisable to install a priming valve on the maintenance of the pump easier.
III - 2.4 CONNECTION DEVICES (See figure 2.1a)
Use connection device adapted to your piping size.
Figure 2.1a
III - 3. DRIP COLLECTION (See figure 1.1a.)
Provide for outlets so that any leak or drips can be easily drained off without any danger. This
is especially important in the case of harmful liquids.
Position a tray under the plain hole located at the bottom of the liquid end mounting assembly
to collect leaks in the event of rupture of the diaphragm or boot.

14
PART IV - START UP
IV - 1.PROCEDURES BEFORE START UP
Special care has to be taken for chemicals used in the process
(acids, bases, oxiding/reducing solutions...).
•Check that the pump is secured to its support (Chapter III - 5. COMMISSIONING).
•Check the pipe fitting torque.
•Check the opening of all the isolating valves installed on the suction and discharge
circuits. If your pump is equipped with a 4-function valve, see the relevant specific
documentation. If the discharge circuit is equipped with an injection nozzle or a
back-pressure valve, open the priming valve on the discharge side (if there is no
priming valve, disconnect the piping on the discharge side). This allows you to
check for the presence of liquid if the pump is installed in flooded suction or to prime
the pump if it is installed in suction lift.
•Set the pump capacity adjustment to 0% (stroke adjustment knob)
•Check the compatibility of the liquid end material with the liquid to be pumped.
IV - 1.1 CHECKING THE ELECTRICAL CONNECTION OF THE MOTOR
Start up the pump to check the motor's direction of rotation. It must comply with that
indicated by the arrow marked on the pump cover.
IV - 2 START UP
•Once all the checks and procedures described in the previous section have been
carried out, start up the pump.
•Check visually and by listening. (In particular, check that there are no suspicious
noises).
•Make sure that the stroke adjustment knob is unlocked.
•Adjust the pump capacity gradually from 0% to 100% and control either.
- The liquid output at priming valve
- or, the noise of the liquid when it discharges from the outlet check valve (if your
installation is not equipped with a Priming Valve).
Priming has been achieved when one of these two processes is carried out.
If a Priming Valve is installed close it, otherwise connect the outlet discharge line.
•Set the pump to the desired capacity. Lock the stroke adjustment knob with the
stroke locking device.
IV- 3. FAILURES ON START UP
IV - 3.1 PROBLEMS WITH MOTOR
The motor runs with difficulty and heats up.
•The characteristics of the electrical power supply do not match the specifications of
the motor.
TRI
Phase
One phase is incorrectly connected.
The electrical connection used is not suitable.
•Check that the pressure on the discharge side is compatible with the equipment’s
capabilities.
•Too many flow pulsations: a pulsation dampener is required, or the pulsation
dampener installed is of the wrong size, or the pressurization of the pulsation
dampener (2/3 of the working pressure).
TRI
Phase
The direction of rotation of the motor is incorrect. (Check using the arrow marked on
the cover). Reverse the direction Procedures.(See Chapter IV - 1.1. Checking the
electrical connection of the motor).

15
IV - 3.2 PROBLEMS WITH FLOW RATE
The flow rate is lower than desired
•The pump capacity is incorrectly adjusted: adjust the capacity to the desired value
and lock the stroke adjustment knob.
•The suction power is insufficient (Piping cross-section too small or piping too long):
replace the pipes with ones with a larger cross-section or install the pump in flooded
suction.
•The leak-tightness of the suction pipes is unsatisfactory.
•The viscosity of the liquid is incompatible with the capabilities offered by your pump
version.
•The filter is blocked, clean it.
The capacity is greater than desired
•The pump capacity is incorrectly adjusted: adjust the capacity to the desired value
and lock the stroke adjustment knob.
•A siphoning phenomenon is observed: check that the discharge pressure is higher
by at least 1,5 bar than the suction pressure. Install a back pressure valve on the
discharge portion
•Too many flow pulsations: a pulsation dampener is required, or the pulsation
dampener installed is of the wrong size, or the pressurization of the pulsation
dampener is incorrect.
The capacity is variable
•This problem may be due to particles from the piping which interfere with the
operation of the valve assemblies: clean the piping and the valve assemblies.
•Lack of back pressure on the discharge portion: install a back pressure valve on the
discharge portion
IV - 3.3 OPERATION - SCHEDULE FOR CHECKS AND MAINTENANCE
OPERATIONS
The programme of checks and maintenance operations depends on the conditions in which
the equipment is used. For the frequency of maintenance, refer to the instruction manual for
installation, operating and maintenance included in the CD-Rom delivered with the pump. You
can adapt the frequency to the conditions of your exploitation.
