The above LKH noise levels are the same for LKHPF, LKHI, LKH UltraPure, LKH Evap and LKHex.
The above SolidC noise levels are the same for SolidC UltraPure.
The noise measurements have been carried out using the original motor and shroud, at the approximate Best Efficiency
Point (BEP) with water at ambient temperature and at 50 Hz.
Very often, the noise level generated by the flow through the process system (e.g. valves, pipes, tanks etc.) is much higher than
what generated by the pump itself. Therefore, it is important to consider the noise level from the total system and take the
necessary precautions with regard to personal safety if required.
