9. The pump should never run dry Never use a stop valve in the suction line to control pump output The stop valve should always be fully opened during operation Check whether the absolute inlet pressure is sufficient to prevent vaporization in the pump Check whether the pressure difference between suction and delivery side corresponds with the specifications of the pump s duty point A mechanical seal may never show visible leakage Noise The noise production of a pump depends to a great extent on the operating conditions The values stated in paragraph 10 7 Noise data are based on normal operation of the pump driven by an electric motor In case the pump is driven by a combustion engine or in case it is used outside the normal operation area as well as in case of cavitation the noise level may exceed 85 dB A In that case precautions should be taken like building a noise barrier around the unit or wearing hearing protection 28 Commissioning 1501 6 6 CombiBloc 5 1 5 2 5 3 5 4 5 5 5 6 eX Maintenance Regular maintenance Regularly check the outlet pressure No water should get into the terminal box of the electric motor when the pump room is sprayed clean Never spray water on hot pump parts The sudden cooling down may cause them to burst and hot water may flow out Flawed maintenance will result in shorter lifespan possible break down and in any event loss of warranty Mec
