0.1 Introduction
CTM is a compact and reliable magnetic drive centrifugal pump made in PP or PVDF. With proper attention
to maintenance, CTM pumps will give efficient and trouble free operation. This instruction manual will
familiarise operators with detailed information about installing, operating and maintaining the pump.
0.2 The warning symbols
The following warning symbols are present in this instruction manual. This is what they say.
This symbol stands next to all safety instructions in this instruction manual where danger
to life and limb may occur. Observe these instructions and proceed with utmost caution in
STOP
these situations. Inform also other users of all safety instructions. In addition to the instructions in this instruction manual, the general safety and accident prevention regulations
must be observed.
This symbol signals possible danger caused by the presence of electric fields or live wires.
Danger magnetic field, indicates the presence of high intensity magnetic fields.
This signal stands at points in this instruction manual of particular importance for compliance with regulations and directives, for correct work flow and for the prevention of damage
to and destruction of the complete pump or its subassemblies.
0.4 Description of the pump
The CTM pumps are centrifugal, single-stage type with magnetic coupling, in close-coupled version,
made from moulded thermoplastic material.
The main feature of these pumps is the transmission of movement by means of a magnetic coupling.
The outer magnetic unit (16), connected to the motor shaft transmits torque to the inner magnetic coreimpeller group (90), the magnetic field generates impeller rotation without physical contact. The isolation
shell (12) is fitted between the two cores sealing hermetically the liquid pumped by the atmosphere,
see figure below.

0.3 Qualification and training of personnel
The personnel in charge of installation, the operation cycle and maintenance of the pumps we produce
must be qualified to carry out the operations described in this manual. Tapflo shall not be held responsible for the training level of personnel and for the fact that they are not fully aware of the contents of

0.5 Health & safety
Electric safety
Do not carry out any maintenance operation on the pump while it is running or before it has been disconnected from the power supply. Avoid any danger caused by electric power (for details see current
regulations in force). Check that electrical specifications on the data plate are equivalent to the power
supply to which it will be connected.

STOP
Avoid pumping liquids, even in different moments that may cause chemical reactions without having
cleaned the pump.
Do not start nor carry out running tests before filling the pump with liquid. Always avoid the dry operation of the pump. Start the pump when it is completely filled with the delivery valve almost fully closed,
limiting this condition to the time that is strictly necessary to start the pump.
The cold or hot parts of the machine must be protected to avoid accidental contacts.
Do not tamper with the protection of the rotating parts, do not touch or approach rotating parts in
movement.
CTM pumps, including the motor, in normal operating conditions produce a sound level below 80 dB(A).
The major sources of noise are: liquid turbulence in the plant, cavitation or any other abnormal operation
that do not depend from the pump construction nor the pump manufacturer. The user must provide
suitable protective means if the sources of noise could produce a harmful noise level for operators and
for the environment (in compliance with current regulations).
1.1 Receiving inspection
Although precaution is taken by us when packing and shipping, we urge you to carefully check the
shipment on receipt. Make sure that all parts and accessories listed on the packing list are accounted for.
Immediately report any damage or shortage to the transport company and to us.
1.2 Storage
If the equipment is to be stored prior to installation, place it in a clean location. Do not remove the pro-
!
tective covers from the suction, discharge and air connections, which have been fastened to keep pump
internals free of debris. Make sure to clean the pump thoroughly before installation.
1.3 Foundation
The pump-motor unit must stand on and be fixed to a sufficiently rigid structure that can support the
!
entire perimeter on which the unit stands. The foundation on a firm bottom are the most satisfactory.
Once the pump is in position, adjust level with metal shims between the feet and the surface on which
it stands. Check that the feet of the pump-motor unit stand well on each of them. The surface on which
the foundation stands must be flat and horizontal. If the unit is fitted on a steel structure, make sure that
it is supported so that the feet do not warp. In any case, it is advisable to fit some antivibration rubber
pieces between the pump and the brickwork.
As the pump is close-coupled type, pump-motor alignment is not required.
1.4 Piping connections
A pump is generally part of a piping system that can include a number of components such as valves,
!
fittings, filters, expansion joints, instruments, etc. The way the piping is arranged and the positioning of
the components has a great influence on operation and the operating life of the pump. The pump cannot
be used as a support for the components connected to it.
The flow of liquid from the pump must be as even as possible. It is advisable to avoid any tight bends or
drastic reductions of diameters that may cause flow resistance in the plant. In case of diameter reduction,
it is advisable to use appropriate conical reductions (possibly eccentric on suction side and concentric
on delivery side) at changes of diameter and at a minimum distance from pump inlets of five diameters.
Powerful magnetic field
Mag-Drive pumps use wide range, high intensity magnets. All pacemaker carriers must not approach
magnetic components; intense magnetic fields can disturb heart pace.
Solids

6 Instruction manual CTM mag drive pumps
It is not recommended to use liquid with suspended solids, especially if sensitive to magnetism.
In case dirty liquids are to be pumped and this was not mentioned at the time of ordering, it is necessary
to contact Tapflo’s technical service before activating the pump.
Any changes concerning the service of the pump as originally purchased, can be executed only after
written approval from Tapflo.
It is recommended to use only genuine Tapflo spare parts and approved accessories. The use of nonoriginal spare parts or non approved accessories will void warranty and removes any responsibility on
our behalf for any damage caused to people or things.
1.4.1 Discharge pipe
A nonreturn valve and a shutoff/regulation valve are normally fitted on the discharge side.
The nonreturn valve protects the pump from any backflow. The shutoff/regulation valve excludes the
!
1.4.2 Suction pipe
!
!
IOM manual Tapflo PE & PTFE series pumps 7
pump from the line and adjusts output. Never adjust flow-rate using the valve on the suction pipe.
The suction piping is very important for the correct operation of the pump group. It must be as short
and as direct as possible. If a longer suction line is unavoidable, the diameter should be large enough,
i.e. at least as the inlet connection on the pump, to ensure less flow resistance. In any case, suction must
be carried out properly avoiding any air locks.
The CTM pumps are single-stage centrifugal type, thus not self-priming. It will therefore always be necessary to install a bottom valve in all cases when the static height of the liquid is lower than the suction
height of the pump. The suction piping must be without air inlets that are more probable with long
suction lines or if suction occurs with negative head. Critical points in these terms are also the seals between flanges and the seals of the valve stems. Even some small air let into the suction line cause serious
operating problems that can make the pump stop.

1.5 Example of installation
1.6 Instruments
In order to ensure a reasonable control of the performance and the conditions of the pump installed, we
!
Electric power
Optional instruments
!
Thermometer
recommend using the following instruments:
- a pressure-vacuum gauge on the suction piping;
- a pressure-vacuum gauge on the delivery piping.
The pressure intakes must be made on straight pieces of piping at minimum five diameters from the
pump inlets. The pressure gauge on delivery must always be fitted between the pump and the shutoff/
regulation valve. The output can be read on the pressure, transformed into meters and then compared
with the typical curves.
The electric power absorbed by the motor can be measured with wattmeters.
The optional instruments can advise of abnormal operating conditions of pumps, such as: valves closed
accidentally, missing liquid, overloads, etc.
If the temperature of the pumped liquid can be a critical element, provide a thermometer (preferably
on suction).
1) YES: gate valve (may also be near pump in the case of long piping)
2) With positive head: tilt of piping towards pump
3) YES: line strainer if particles are present
4) NO: air pockets: the circuit must be short and straight
5) YES: pipe fixing parts
6) Suction line as short and direct as possible
7) YES: check valve (especially for long vertical or horizontal pipes; compulsory with parallel
pumps)
8) YES: adjusting gate valve on outlet
9) Bends placed after valves and instruments
10) YES: attachment for gauge or safety pressure switch
11) NO: elbow joints (and other parts) on the pump (discharge and suction lines)
12) With negative suction lift: tilt of piping towards suction tank
13) YES: check valve (with negative suction lift)
14) YES: strainer if particles are present
15) Suction head varies according to flow in order to prevent windage
16) Suction head
17) Immersion depth
18) YES: expansion joint (indispensable with long pipes or hot liquids) and/or anti-vibration facility
during discharge and suction; anchored near to pump
19) YES: pipe discharge (completely sealed), discharge valve shut during normal operations
20) YES: overcoming obstacles at lower depths
21) Fix the pump by the fixing holes provided: the supports must be level
22) YES: drainage channel around base
1.7 Motor Connection
An expert electrician must always carry out the electrical connection. Compare the power supply with the
data plate specifications and then choose a suitable connection. The type of connection is stated on the
motor data plate that can be Y (star) or D (Delta), according to the power supply of the motor (see figure).
Star connection Y Delta connection D
Follow the prescriptions of the local electricity board for the connection. In no case connect the electrical
motors directly to mains but also fit in between a suitable electric switchboard equipped with a knife
switch and suitable safety devices. Safety devices against overloads must protect the motors. Make sure
that the motor has suitable grounding and that it has been connected properly.

2. OPERATION
2.1 Start-up
- Check manually that the motor is free to turn, moving the motor cooling fan.
3. MAINTENANCE
Maintenance work on electrical installations must be performed by qualified personnel
and only when the power supply has been shutoff. Follow the local and national safety
regulations.
- Make sure that the piping is not clogged and is free from residues or foreign objects. Make sure that
the liquid flows regularly into the pump.
- The pump and piping connected to it, at least the suction pipe, must be full of liquid. Any air or gas
!

STOP
2.1.1 Starting the pump
!
must be carefully released. In case of suction with negative head, fill the suction piping and check how
the bottom valve works. It must guarantee that the liquid must not flow back, emptying therefore
the suction pipe with consequent disconnection of the pump.
- The suction shutoff valve (if any) must be completely open.
- The shutoff/regulation valve on the discharge side must be almost completely closed.
- The motor must turn in the same direction as the arrow shown on the pump. The direction of rotation
is always clockwise looking at the pump from the motor side; check by starting briefly, then looking at
the direction of rotation of the motor fan through the fan lid. If it is wrong, the motor must be stopped
immediately. Change the connection to the terminals of the electric motor (chapter 1.7) and repeat
the procedure described above.
- Any auxiliary connections must all be connected.
Start the electric motor and open the discharge adjustment/shutoff valve gradually until the desired
output has been reached. The pump must not turn more than two or three minutes with discharge closed.
A longer operation in these conditions can damage the pump seriously.
3.1 Maintenance schedule
The CTM range pumps have been designed and tested to run for 5000 hours in ideal working conditions.
Please note that is a conservative figure since the actual duty point of your pump can substantially modify
such value. Additional factors such as intermittent operation, type of pumped liquid and installation in
the plant may affect the life of components subject to wear.
In any case, Tapflo advises to service pumps every year of service, even when used in ideal operating
conditions.
3.2 Trouble shooting
The following tables help to identify the causes of any problems during operation or failures of the pump.
By consulting table ”A” identify on the left column (symptoms) the problem encountered on the right
column (causes) the number relevant to the possible causes of malfunctioning. Table ”B”, by excluding
the causes not applicable to the case being examined, allows to identify the causes of the problem.
If the pressure shown on the pressure gauge on the discharge piping does not increase, turn off the pump
immediately and release pressure carefully. Repeat the connection procedure.
If there are changes of flow-rate, head, density, temperature or viscosity of the liquid, stop the pump and
!
2.1.2 Re-starting after power shutoff
get in touch with our technical service.
In case of accidental stopping, make sure that the non-return valve has prevented backflow and check
that the motor cooling fan has stopped. Start the pump again following the instructions of chapter 2.1.1
”Starting the pump”.
If the pump intakes from a lower level, it can unprime during the standstill and therefore you must check
again before starting that the pump and the suction piping are full of liquid.
2.2 Stopping the Pump
It is advisable to close the discharge adjustment/shutoff valve gradually and stop the motor immediately
!
after. The reverse sequence is not recommendable, especially with larger pumps or longer delivery piping.
That is to avoid any problems due to water hammering. If a suction shutoff valve has been installed, it
is advisable to close it completely.

3.3.1 Disassembly of the pump
The assembly and disassembly should only be performed by qualified personnel.
Each operation carried out on the machine must always be carried out once all the electrical contacts
have been disconnected. The pump-motor unit must be placed in a position where it cannot be started
unintentionally.
Before servicing in any way the parts in contact with the pumped liquid, make sure that the pump has
been fully emptied and washed. When draining the liquid, make sure that there is no danger for people
or the environment.
For dismantling the pump proceed as follows (see drawing below):
Dismantle the pump casing (13) from the lantern (11), by loosening screws (141) washers (142) and nuts
(143).
Pull out the static bushing (1521) from the casing.
For CTM 20-7: remove the impeller magnet assembly (90) extract rotating bushing (1511) and rear bushing
(1512) and the O-ring (1812).
For CTM 25-8 and 25-10: remove the impeller magnet assembly, extract rotating bushings (1511) and
(1512) and the O-rings (1811) and (1812).
The static and rotating bushes are usually made from very fragile sintered material and therefore has to
be handled with extreme care.
Remove the casing O-ring (18) from the isolation shell (12).
Extract the isolation shell (12) from the lantern (11).
Loosen the lock screws (161).
Remove the external magnet assembly (16) from the lantern (11) loosening the screws (111).
