850 SERIES
PRODUCT DESCRIPTION
The Griswold 850 Series pump is a centrifugal single-stage close-coupled pump which is also offered as
a frame-mounted pump. The pump has a back pull-out design, meaning that it is possible to remove the
pump back-end without disturbing the case and piping, which can facilitate easier maintenance of the
pump. The casings are of a single-casting design with an end-suction tangential-discharge configuration.
The close coupled pumps are designed to bolt onto standard JM and JP motor frames.
Each pump will be supplied with a factory installed nameplate. See the figure for a description of each
nameplate field.
