5. Product introduction
5.1 Applications
Grundfos LS horizontal split case pumps are typically
used in these applications:
•
circulation in heating and air conditioning
systems, water condensing and boiler feed
systems
•
liquid transfer and pressure boosting in various
industrial systems
•
water distribution and water treatment in public
water systems.
5.2 Pumped liquids
Clean, thin, non-aggressive liquids, not containing
solid particles or fibres. Do not pump liquids that will
attack the pump materials chemically.
When pumping liquids with a density and/or viscosity
higher than that of water, the head and flow will be
reduced. Alternatively, use motors with
correspondingly higher outputs.
The stuffing box packing rings or mechanical shaft
seal O-rings chosen must be suitable for the liquid to
be pumped.
Special stuffing box packing rings or shaft seal
O-rings may be required if you use the pump for
pumping treated water:
•
at temperatures above 80 °C (176 °F).
•
containing additives to prevent system corrosion,
calcareous deposits, etc. (this may be the case in
heating and ventilating systems).
When pumping liquids other than water, select an
appropriate stuffing box or shaft seal. For further
information, contact Grundfos.
5.3 Identification
The type designation and rating information of
Grundfos horizontal split case pumps are stated on
the nameplate. See fig.
. The type designation
includes model number, size and type.
Permanent records for this pump are kept under its
year-week code and serial number (fig.
, 4 and 5)
and this number must therefore be stated in all
correspondences and spare parts orders.
For more information about weight, see the label on
the packaging.
