Notes:
1) F = External force (tension or compression).
M = External moment, clockwise or counter-clockwise.
Sign convention follows ISO1503 and ISO13709/API610.
2) Forces and moments may be applied simultaneously in any
direction.
3) Values apply to all materials.
4) Higher loads may be applicable, if direction and magnitude of
individual loads are known, but these need written approval
from Flowserve Pumps.
5) Pumps must be on rigid foundations and baseplates must be
fully grouted
6) Pump/baseplate should not be used as pipe anchor. Suction
and discharge piping should be anchored as close as possible
to the pump flanges to reduce vibration and prevent strain on
the pump casing. Expansion joints are recommended. They
must be properly tied and located on the side of the pipe anchor
away from the pump.
7) The pump mounting bolt torques specified must be used to
prevent relative movement between the pump casing and
baseplate. (See section 6.6, Fastener torques.) The bolt
material must have a minimum yield strength of 600 N/mm
2
(87 000 lb/in.
2
).
