I - 3. OPERATING PRINCIPLE OF THE MECHANICAL ASSEMBLY

Drawing 1066085010

The movement of rotation of the motor is transmitted by the worm [052B] to the tangent wheel [052A],
herself connected to the eccentric [016] by the finger [037H].

The system of rod and eccentric transforms the rotative movement in a linear movement The
crosshead connected to the connecting rod move with an adjusting linear stroke.The stroke of the
crosshead [010] depends on the position of the eccentric female [016A] in relation to the eccentric
male [016].

I - 4. OPERATING PRINCIPLE OF THE MECHANICAL ASSEMBLY

Refer to chapter VII « Servicing the liquid end »

1 - 5. SAFETY AND HEALTH INSTRUCTIONS

acquainted with, assimilate and comply with the contents of this manual in order to:

• avoid any possible risk to themselves or to third parties,

• ensure the reliability of the equipment,

• avoid any error or pollution due to incorrect operation.

Any servicing on this equipment must be carried out when it is stopped. Any accidental start-up must
be prevented (either by locking the switch or removing the fuse on the power supply line).
A notice must be attached to the location of the switch to warn that servicing is being carried out on
the equipment.

During oil changing operations, the waste oil must be collected in a suitable receptacle. Any overflow
of oil which may result must be removed using a degreasing agent suitable for the operating
conditions.

Soiled cleaning cloths must be stored in suitable receptacles. The oil, degreasing agent and cleaning
cloths must be stored in accordance with the rules on pollution.

Switch off the power supply as soon as any fault is detected during operation: abnormal heating or
unusual noise.

Special care has to be taken for chemicals used in the process (acids, bases, oxiding/reducing
solutions, ...).

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.

II - 2. DRIP COLLECTION

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.

The electrical protection for the motor (fuse or thermal protection) must be suitable for the motor's
rated current.

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.
