Health & safety
Electric safety
Do not carry out any maintenance operation on the pump while it is running or before it has been dis-
connected 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.
Chemical hazards
Avoid pumping liquids, even in different moments that may cause chemical reactions without having
cleaned the pump.
Dry running
Do not start nor carry out running tests before filling the pump with liquid. Always avoid the dry opera-
tion 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.
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
CT 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 opera-
tion 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).
Cleaning & disinfection
Cleaning and disinfection of the pump system is of greatest importance when the pump is used in a food
process installation. Use of a pump system that is NOT cleaned or disinfected can cause contamination
of the product.
