is non-flammable and is resistant to a wide range of solvents, mineral and organic acids and alkalis. It must NOT be
used with the following:
 Bromine (wet)
 Butyl Amine
 Chlorosulfonic Acid
 Chlorine (dry)
 Chromic Acid Conc
 Hydrogen peroxide 30%
 Morpholine
 Nitric Acid 35% to Conc
 Sulphuric Acid 98%

Riffled nozzles are provided on the pump for the water and vacuum connections and an internal non-return valve
prevents flooding of the vacuum system in the event of fluctuating water pressure.
