PART II - INSTALLATION
II - 1. HYDRAULIC INSTALLATION
All the information concerning the hydraulic installation of a metering pump is detailed in a volume,
«Generalities about dosing pumps installation ». You should consult that manual to define the
installation required for your application. However the main items are describe hereafter.
GENERAL
•Piping layout
•There must be no swan-necks or stagnant volumes which can trap air or gas.
•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.
PIPING ON THE SUCTION CIRCUIT
•Provide for a filter with suitable mesh size upstream of the pump.
•Check whether the diameter and length of pipe are compatible with the pump's maximum
capacity.
PIPING ON THE DISCHARGE CIRCUIT
•Provide for a safety valve on the discharge pipe, designed to protect the installation.
•It is advisable to install a priming valve on the discharge circuit in order to make starting and
maintenance of the pump easier.

It’s recommended to install a drain system to collect the leakage and the drip, especially if the liquid
pumped is harmful
II - 3. HANDLING
Handling the pump
The lifting equipment must becompatible with the pump weight. (Refer to the pump signaletic plate)
The handling requires the following precautions :
•Fit the sling through the rings on the pump
•Check that the assembly is correctly balanced before starting to move it.
•Fix the pump as soon as it is positioned in correct location (see Chapter II - 4. Setting up).
Handling The Motor
The lifting equipment must be compatible with the motor weight (Refer to the motor signaletic plate).
Fit a sling in each ring on the motor.
Check that the motor is correctly balanced before starting to move it.
II - 4. SETTING UP
Pump Installation
Fix by the fixing holes the pump to an horizontal support correctly dimensioned. Leave enough clear
space around the pump to be able to carry out servicing operations and adjustments.
Pumps installed outdoors must be protected by a shelter (according to the climatic conditions).
II - 5. ELECTRICAL INSTALLATION
Connecting The Motor
Check the specifications of the motor and compare them with the voltage available on your installation
before making connections. Connect up the motor in accordance to the indications specified in the
connecting box.
Do not forget to connect the earth terminal of the motor [PE] to the equipment earth conductor.

PART III - START UP
III - 1. PROCEDURES BEFORE START UP
Special care has to be taken for chemicals product used in the process (acids, bases, oxiding/reducing
solutions, ...).
•Check the pump fixation(Chapter II - 4. Setting Up).
•Remove the filling plug and fill the housing with lubricating oil (Chapter IV-1. Oil Change) supplied up to
the middle of the level indicator. Reinstall the filling plug.
Check the opening of all isolating valves installed on the suction and discharge circuits.
Disconnect discharge circuit ( caution to the liquid pumped). This procedure is to verify that there is
liquid present (pump is installed in flooded suction), or to prime the pump (pump installed in suction lift).
•Check that the pump capacity is set to "0%" (hand-knob).
III - 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 hand-knob is unlocked.
•Adjust the pump capacity gradually from 0 % to 100% and control the liquid output at priming
valve.
•As soon as the liquid to be pumped flows out of the priming valve, priming on the process side has
been achieved. Close the priming valve or reconnect the discharge pipe, as applicable.
•Once the priming is obtained, adjust the pump to the desired capacity.
•Lock the hand-knob with the locking screw
III - 3. FAILURES ON START UP
The motor runs with difficulty and heats up
•One phase is incorrectly connected.
•The characteristics of the electrical power supply do not match the specifications of the motor.
•The electrical connection used is not suitable.
•The housing does not contain any oil. Fill up with oil (See Chapter III - 1. Procedures Before Start Up).
The flow rate is lower than desired
•The pump capacity is incorrectly adjusted: adjust the capacity to the desired value and lock
the hand-knob.
•The suction power is insufficient (pipe cross-section too small or pipe too long): replace the
pipe with ones that have a larger cross-section or install the pump in flooded suction.
•The leak-tightness of suction pipe is unsatisfactory.
•The viscosity of the liquid is incompatible with the pump's capabilities.

M0012001a /7

The capacity is greater than desired
•The stroke adjustment of debit of the pump is incorrect: to adjust the debit to the wanted value
•A syphoning phenomen is observed: check if the suction pressure is not superior to the discharge
pressure . So necessary, to place a back-pressure valve on the discharge line.
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 (by checking the assembly sequence
of different components).
III - 4. SCHEDULE FOR CHECKS AND MAINTENANCE OPERATIONS
•The programme of checks and maintenance operations depends on the conditions in which the
equipment is used. For this reason, the following frequencies are given as an example only.
Individual users should adapt these frequencies to their own specific operating conditions.

IV - 2. OTHER MAINTENANCE OPERATIONS
TRACING A OIL LEAKAGE
•Check that the drain plug is correctly tightened.
•Check for leakage on the shaft on the motor side. If a leakage is found, change the seals on the
worm shaft.
•Check for leakage on the micrometer screw. If a leakage is found, change the seal on the
micrometer screw.
CHECKING THE PUMP CAPACITY
This is a question of determining the straight line representing the pump's capacity according to its
adjustment.Four measurements are sufficient (adjustment at 100%, 75%, 50% and 25%).There are
two possible methods:
If the pump is installed in pressurizing mode
Measure the volume of pumped liquid in a calibrating chamber for a given period of time. It may
be necessary to reproduce actual operating conditions (suction pressure).
If the pump is installed in suction mode
Measure the volume of discharged liquid. It may be necessary to reduce actual operating
conditions (discharge pressure).
The first method is recommended. In addition, this method avoids placing the operator in contact
with the liquid, which is important if the pumped liquid is hazardous.
For a precise check, it may be necessary to use an electromagnetic flowmeter.
IV - 3. TRACING CAUSES OF FAILURE
PROBLEMS WITH MOTOR
The motor does not run :
•The thermal relay has been tripped.
•The motor is defective.
•Wiring is defective.
The motor heats abnormally :
•The quantity of lubricating oil is incorrect: trace the leak (see Chapter IV - 2.)
•The quality of the lubricating oil is incorrect. Check the date of the last oil change and the
specifications of the oil used.
•The pump is used in conditions it was not designed for.

PROBLEMS WITH NOISY MECHANICAL PARTS
•The bearings can be weared, replace them if necessary
•The motor coupling can be weared, replace it if necessary
PROBLEMS WITH FLOW RATE
The pump produces no flow
•The pump capacity is adjusted to « 0 % » : Adjust the capacity to the desired value and lock
the hand-knob.
•Check the leak-tightness of the piping safety valve.
•The liquid end is unprimed: release the pressure on the discharge pipe and prime the liquid
end, or check the leak-tightness of the suction circuit.
•The balls of the valve assemblies are blocked by particles: clean or replace the valve
assemblies.
•First, check whether the presence of the particles in the valve assemblies is normal and take
corrective action if necessary.
•If the problem is not solved chek the mechanial assembly and liquid end functionning.
The pump does not provide the required flow rate
•The pump capacity is incorrectly adjusted: adjust the capacity to the desired value and lock the
hand-knob.
•The valve assemblies are blocked by particles: clean or replace the valve assemblies.
•The suction circuit leak-tightness is unsatisfactory.
