0. GENERAL

0.1. Introduction

CTM is a compact and reliable magnetically driven centrifugal pump made in PP and 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. 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 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 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.

This symbol indicates possible danger caused by strong magnetic field in the
vicinity of the pump.

This symbol signals possible danger caused by the presence of electric fields or
live wires.

0.3. Qualification and training of personnel

The personnel in charge of installation, operation 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 this manual.

1. INSTALLATION

IOM manual CTM mag drive pumps 5

1. INSTALLATION

1.1. Operation principle

In the CTM pump the torque from the motor shaft is transmitted to the impeller by means
of a magnetic coupling. The drive magnet (1) is fixed on the motor shaft. The magnets
installed in the drive magnet and in the impeller/magnet assembly (2) have different polarity.
When the pump is at rest, the magnets of both parts are aligned. When the motor is started
and the drive magnet starts to rotate, the magnets create an attraction and repulsion force
thus forcing the impeller to rotate. If the impeller gets blocked or the pumped liquid will be
too dense and too much torque will be generated on the motor shaft, the magnet will de­couple and no damaged will be done to the motor. When the pump will come to a stop, the
magnets will re-couple. Between both magnet assemblies there is located an isolation shell
(3) that separates the liquid side from the motor side.

1.2. 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. INSTALLATION

IOM manual CTM mag drive pumps 6

1.3. Storage

If the equipment is to be stored prior to installation, place it in a clean location. Clean the
pump thoroughly before installation.

1.4. 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 is
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 anti-vibration rubber pieces between the pump
and the brickwork.

For close-coupled type, pump motor alignment is not required.

1.5. Environment

➢ There should be enough space in the vicinity of the pump in order to operate, maintain

and repair it.

➢ The area in which the pump is operated, must be sufficiently ventilated. Excessive

temperature, humidity or dirt may affect the pump operation.

➢ Behind the cooling fan of the motor there must be sufficient room for the hot air to

escape the motor.

1.6. Suction and discharge piping

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 the operation and the
lifetime 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
installation. In case of diameter reduction, it is advisable to use appropriate conical reductions
(possibly eccentric on suction side and concentric on discharge side) at changes of diameter
and at a minimum distance from pump connections of five diameters.

1.6.1. Connection of discharge pipe

A shut-off / regulation valve is normally fitted on the discharge side. It cuts off the pump
from the line and adjusts the output. Never adjust flow rate using the valve on the suction
pipe.

1. INSTALLATION

IOM manual CTM mag drive pumps 7

1.6.2. Connection of suction pipe

The suction piping is very important for the correct operation of the pump assembly. 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 non 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 a bit of air let into the suction line can cause serious operating problems that can make
the pump stop.

1.7. Health and safety

The pump must be installed according to local and national safety rules.

The pumps are constructed for particular applications. Do not use the pump on
applications different from that for which it was sold without consulting us to ascertain
its suitability.

1.7.1. Protection

In the interest of health and safety it is essential to wear protective clothing and safety
goggles when operating, and/or working in the vicinity of Tapflo pumps.

1.7.2. Electrical safety

Do not carry out any maintenance or/and 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 motor
nameplate are equivalent to the power supply to which it will be connected.

1.7.3. Chemical hazard

Whenever the pump is to be used for pumping a different liquid, it is essential to clean the
pump beforehand in order to avoid any possible reaction between the two products.
Before pump disassembly clean it thoroughly.

1.7.4. Dry running

Do not start nor carry out running tests before filling the pump with liquid. Always avoid dry
operation of the pump. Start the pump when it is completely filled and with the valve on the
discharge side almost completely closed.

1. INSTALLATION

IOM manual CTM mag drive pumps 8

1.7.5. Noise level

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 installation, cavitation
or any other abnormal operation that is independent 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 local regulations).

1.7.6. Temperature hazards

Raised temperature can cause damage on the pump and/or piping and may also be
hazardous for personnel in the vicinity of the pump/piping. The hot or cold parts of the
machine must be protected to avoid accidental contacts

1.7.7. Rotating parts

Do not tamper with the protection of the rotating parts, do not touch or approach rotating
parts in movement.

1.7.8. Powerful magnetic field

Magnetically driven pumps use high intensity magnets. All pacemaker carriers must not
approach magnetic components; intense magnetic field can disturb heart pace.

1.8. Solids

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 technical service before activating the pump.
Acceptable solid size for all CTM pumps is 0,1 mm (100 microns).
Maximum solids concentration by weight is 2%.

1. INSTALLATION

1. INSTALLATION

IOM manual CTM mag drive pumps 10

1.10. Instruments

In order to ensure a proper control of the performance and the conditions of the installed
pump, we recommend using the following instruments:

- a pressure-vacuum gauge on the suction piping;

- a pressure gauge on the discharge piping.
The instruments must be installed on straight pieces of piping at a distance not bigger than
five diameters of the pipeline from the pump connections. The pressure gauge on discharge
must always be fitted between the pump and the shut-off / regulation valve. The output can
be read on the pressure gauge, transformed into meters and then compared with the typical
curves.

1.10.1. Electric power

The electric power absorbed by the motor can be measured by means of a wattmeter.

1.10.2. Optional instruments

The optional instruments can indicate if pump is working in an abnormal way. The abnormal
conditions can be caused by: accidentally closed valves, lack of pumped liquid, overloads,
etc.

1.10.3. Thermometer

If the temperature of the pumped liquid is a critical parameter, provide the installation with
a thermometer (preferably on the suction side).

1.11. 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 and can be Y (star) or D (Delta), according to
the power supply of the motor (see table below).

STAR

DELTA

Follow the connection standard used in the plant. In no case connect the electrical motor
directly to supply network but use a suitable electric switchboard equipped with a knife
switch and suitable safety devices (e.g. motor breaker switches) in the power circuit. Safety

1. INSTALLATION

IOM manual CTM mag drive pumps 11

devices against overloads must also 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 by moving the motor cooling fan.

➢ 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 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 and eventually disconnection
of the pump.

➢ The suction shut-off valve (if any) must be completely open.

➢ The shut-off / regulation valve on the discharge side must be 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 1.11 “Motor connection”) and repeat the
procedure described above.

➢ Any auxiliary connections must all be connected.

2.1.1. Starting the pump

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.

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 get in touch with our technical service.

2. OPERATION

IOM manual CTM mag drive pumps 12

2.1.2. Restarting after power shut-off

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”.

2.2. Stopping the pump

It is advisable to close the discharge shut-off / regulation valve gradually and stop the motor
immediately after. The reverse sequence is not recommended, 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. MAINTENANCE

IOM manual CTM mag drive pumps 13

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.

3.1. Inspections

The CTM range pumps have been designed and tested to run for 5000 hours in ideal
working conditions. Please note that it is a conservative figure since the actual duty point of
your pump can substantially modify this value. Additional factors such as intermittent
operation, type of pumped liquid and installation in the plant may affect the life of
components that are subject to wear. In any case, Tapflo advises to service pumps every
year, even when used in ideal operating conditions.

➢ Periodically check suction and discharge pressures.
➢ Inspect the motor according to the instructions from the motor manufacturer.

3. MAINTENANCE

IOM manual CTM mag drive pumps 15

3.3. Disassembly of the pump

The 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 that come 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.

The static and rotating bushings are usually made from very fragile sintered material and
therefore have to be handled with extreme care.

The numbers put in brackets, refer to the part numbers in the spare part drawings and spare
part lists in chapter 4 “Spare parts”.

Nevertheless there are a few things that you have to remember in order to assemble the
pump correctly.

Fig. 3.4.1

Wet the O-rings with alcohol before assembly to make
the procedure easier.

3.4.1. Test run

We recommend you to conduct a test run of the pump before installing it in the system, so
no liquid gets wasted if the pump leaks or perhaps does not start accordingly to wrong
assembly of the pump.
After a few weeks of operation retighten the screws with appropriate torque.
