Cleaners, Disinfectants and Descalents
On installations where chemical disinfectants or descalents are periodically
used, the compatibility of the chemical solution regarding the pump must be
considered.
Acid based descalents and aggressive cleaning agents must not come into
contact with the pump. The pump must be removed from the system prior to the
use of these products. The system should be flushed to remove all chemicals
before the pump is re-connected.
If in any doubt as to the suitability of the chemical solutions refer to Stuart
Turner Ltd.
