2. PUMPED
LIQUIDS
KC – KCV pumps are horizontal single-stage
centrifugal pumps for pumping clean liquid, non
explosive fluids, without solid particles or fibres that
can attack the pump mechanically or chemically.
The pumps must not be used for the
transfer of inflammable or toxic
liquids.
If ethylene glycol or propylene is
added to the pumped liquid, the
concentration must not exceed 45%.
