DESCRIPTION
The VSC and VSCS Series centrifugal pumps are frame mounted
pumps which feature – high efficiency, rugged construction,
compact design, foot mounted volute, center drop out coupler,
and regreasable bearings. These features along with the verti-
cally split case make installation, operation, and service easy to
perform.
PUMP APPLICATION
The standard VSC and VSCS Series centrifugal pump’s br
onze
fitted construction make it ideal for service with the following
liquids: unheated domestic and fresh water, boiler feed water
,
condensate, hydronic cooling or heating, pressure boosting,
general pumping and benign liquids.
For other applications contact your local B&G Representative.
OPERATIONAL LIMITS
Unless special provisions have been made for your pump by
Bell & Gossett, the operational limits for VSC/VSCS Series
Pumps are as follows:
Maximum Working Pressur
e
Listed on pump nameplate.
SEAL OPERATING LIMITS
Standard Seals
BUNA-PH Limitations 7-9; Temperature Range -40 to +225°F
EPT-PH Limitations 7-11; Temperature Range -40 to +250°F
For use on closed or open systems which are relatively free of
dirt and/or other abrasive particles.
Flushed Single Seals
PH Limitations 7-9; Temperature Range 0 to +250°F†
Note: On closed or open low pressure systems which may
contain a high concentration of abrasives an external flush is
required.
Flushed Double Seals
PH Limitations 7-9; Temperature Range 0 to +250°F
Note: On closed or open low pressure systems which may
contain a high concentration of abrasives an external flush is
required.
Packing
PH Limitations 7-9; Temperatur
e Range 0 to +200°F
Note: On open or closed systems which require a large
amount of makeup water, as well as systems which are sub-
jected to widely varying chemical conditions and solids buildup.
† For operating temperatures above 250°F a cooled flush is requir
ed
and is recommended for temperatures above 225°F for optimum seal
life. On closed systems cooling is accomplished by inserting a small
heat exchanger in the flush line to cool the seal flushing fluid.
Flush-line Filters and Sediment Separators are available on special
request.
