Notes:

1) F = External force (tension or compression).

M = External moment, clockwise or counter-clockwise.

2) Forces and moments may be applied si multaneously in any

direction.

3) Val ues apply to all materials.

4) Higher loads maybe applicable, if directi on and magnitude of

indivi dual loads are known, but these need written approval

from Flowserve Pump Di vision.

5) Pumps must be on rigid foundations and baseplates must be

fullygrouted.

6) Pump/baseplate should not be used as pipe anchor. Sucti on

and discharge piping should be anchored as close as possible

to the pump flanges to r educe vibration and prevent strain on

the pump casing. Expansion joints are r ecommended. They

must be properl ytied and l ocated on the side of the pipe anchor

awayfrom 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.). T he bolt

material must have a minimum yiel d strength of 600 N/mm

(87 000 l b/in.
