Page 5: General
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. -
Page 6: Installation
INSTALLATION 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. -
Page 7: Storage
INSTALLATION 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. -

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. -
Page 9: Noise Level
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). -
Page 10: Example Of Installation
INSTALLATION 1.9. Example of installation 1) YES: Gate valve (may also be near pump in 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 fastening 6) Suction line as short and direct as possible 7) YES: adjusting gate valve on outlet... -
Page 11: Instruments
INSTALLATION 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. -
Page 12: Operation
INSTALLATION devices against overloads must also protect the motors. Make sure that the motor has suitable grounding and that it has been connected properly. OPERATION 2.1. Start-up ➢ Check manually that the motor is free to turn by moving the motor cooling fan. ➢... -
Page 13: Restarting After Power Shut-Off
OPERATION 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. -
Page 14: Maintenance
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. -

Page 16: Disassembly Of The Pump
MAINTENANCE 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. - Page 17 MAINTENANCE Fig 3.3.3 Pull out the impeller / magnet assembly [90] from the isolation shell [12]. NOTE! Take extra care while proceeding with this point. The magnetic field generated by the magnets can cause finger seizure between the impeller and the impeller [90] and isolation shell [11].
- Page 18 MAINTENANCE Fig 3.3.8 Take out the isolation shell [12] form the lantern [11]. Fig 3.3.9 Pull out the rear static bushing [1522] along with the O- ring [1822]. Fig 3.3.10 Loosen the lock screws (2 x [161] on CTM20/25; 1 x [1611] and 2 x [1612] on CTM32).
