0. GENERAL
0.6 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 specications on the data plate are equivalent
to the power supply to which it will be connected.
Chemical hazards
Avoid pumping liquids, even in different moments that may cause chemical reactions without
having cleaned the pump.
Temperature hazards
The cold or hot parts of the machine must be protected to avoid accidental contacts.
Rotating parts
Do not tamper with the protection of the rotating parts, do not touch or approach rotating parts in
movement.
Noise level
CTV 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).
Modifications and Spare parts
Any changes concerning the service of the pump as originally purchased, can be executed only
after written approval from Tapo.
It is recommended to use only genuine Tapo spare parts and approved accessories. The use
of non-original spare parts or non approved accessories will void warranty and removes any re-
sponsibility on our behalf for any damage caused to people or things.

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 protective covers from the suction and discharge, which have been fastened
to keep pump internals free of debris.
- Store the pump on the motor fan cover in an upright position, or hang the pump from the cover
plate.
- Make sure to clean the pump thoroughly before installation.
1.3 Installation
- CTV pumps must be installed vertically and can be used in sumps, tanks and similar contai-
ners.
- For a safe "outside tank" installation always consult us for arrangement of neccessary modi-
cations.
- Install the pump on a rigid support and fastened by the cover plate.
1.4 Piping
A pump is generally part of a piping system that can include a number of components such as
valves, ttings, lters, expansion joints, instruments, etc. The way the piping is arranged and the
positioning of the components has a great inuence on operation and the operating life of the
pump. The pump cannot be used as a support for the components connected to it.
The ow 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 ow resistance in the plant. In case of
diameter reduction, it is advisable to use appropriate conical reductions.
Discharge pipe
If the discharge height is more than 2 meters, a check valve shoiuld be installed in the discharge
line (see installation example, chapter 1.5)
Suction extension
Use of extension pipe is possible on CTV pumps to allow emptying from a lower level. The liquid
level can drop under the impeller (pump casing) during operation. However during startup the level
must always be over the impeller (pump casing). See installation example, chapter 1.5.
Return flow
To avoid return ow, a check valve is recommended on the discharge side as near to the pumps
as possible. It is of greatest importance in installations with high discharge height. See installation
example, chapter 1.5.

1.6 Instruments
In order to ensure a reasonable control of the performance and the conditions of the pump instal-
led, we recommend using the following instruments:
- a pressure-vacuum gauge on the delivery piping.
The output can be read on the pressure, transformed into meters and then compared with the
typical curves.
Electric power
The electric power absorbed by the motor can be measured with wattmeters.
Optional instruments
The optional instruments can advise of abnormal operating conditions of pumps, such as: valves
closed accidentally, missing liquid, overloads, etc.
Thermometer
If the temperature of the pumped liquid can be a critical element, provide a thermometer.
1.7 Motor Connection
An expert electrician must always carry out the electrical connection. Compare the power supply
with the data plate specications 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 gure).
Star connection YDelta connection D
Follow the prescriptions of the local electricity board for the connection. In no case connect the elec-
trical motors directly to mains but also t 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
- The motor shall be connected by qualied personnel only.
- Check manually that the motor is free to turn, moving the motor cooling fan.
- Make sure that the piping is not clogged and is free from residues or foreign objects.
- Bump start the motor to determine the direction of rotation (indicated with an arrow on the
motor). If change is necessary, follow instruction in chapter 1.7.
- The shutoff/regulation valve on the discharge side must be almost completely closed at start-
up.
- Any auxiliary connections must all be connected.
2.1.1 Starting the pump
- When ever starting the pump, the pump casing must be lled with liquid, see MIN start level in
chapter 1.5.
- 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.
- 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 ow-rate, head, density, temperature or viscosity of the liquid, stop the
pump and get in touch with our technical service.
- During operation, make sure the liquid level is within the limits, see levels H min and MIN in
chapter 1.5.
2.1.2 Re-starting after power shutoff
In case of accidental stopping, make sure that the non-return valve has prevented backow 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 adjustment/shutoff valve gradually and stop the motor imme-
diately 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.
