2. General information
Grundfos booster modules BME and BMET are supplied from the
factory in boxes in which they should remain until they are to be
installed. The modules are ready for installation.
2.1 Pumped liquids
Thin, non-explosive liquids, not containing solid particles or
fibres. The liquid must not chemically attack the booster module
materials. In case of doubt, contact Grundfos.
Warning
The booster modules must not be used for the
pumping of inflammable liquids such as diesel
oil, petrol or similar liquids.
We recommend that you filter the raw water to maximum 30
microns.
The booster modules must never operate with water/liquid
containing substances which would remove the surface tension,
e.g. soap. If this type of detergent is used for cleaning of the
system, the water/liquid must be led around the modules via a
bypass.
During transportation and storage, the booster
modules must never be preserved with glycerine
Caution
or similar liquids which are aggressive to the
booster module materials.
