SPRING MOUNTED BASE

Fig. 8 shows a V-belt driven AF pump on a spring
mounted sub-base. Sub-bases supported by spring
pockets assure that the pump remains level,
regardless of vertical movement due to thermal pipe
expansion during operation.

The following is a brief description of the spring pocket
components and their function (see Fig. 9). The
adjusting screw is used to compress or relax the
spring. Turning the screw causes the adjusting screw
nut assembly to move vertically and change the
amount of force the spring exerts against the spring
retainer, which is fastened to the sub-base. The stop
nut is to limit the vertical up motion of the sub-base in
case part of the load is removed from the pump unit
