CHAPTER 3
VOLUTE BODY
Removing & Refitting
Slacken the clips and disconnect the rubber hose from the priming valve to the primer.
Remove the sixteen bolts and sealing washers which attach the volute body to the pump
head and remove the volute body.
When re-assembling, ensure that the flange faces are clean. Fit a new joint washer with
a smear of jointing compound.
A 5/8” UNC stud, fitted temporarily into one of the tapped holes in the volute body, will be
useful in guiding the volute body into position when re-assembling.
CHAPTER 4
PRIMING VALVE
Maintenance Attention
The priming valve may be left in position for examination of internal components, but if it
is necessary to remove the valve, remove the priming pipe and rubber hose from the
valve and remove the nuts, spring washers, plain washers and bolts which secure it to its
bracket. Lift off the valve.
To dismantle the valve, remove the three nuts, spring washers, plain washers and bolts
which retain the end plates. These can then be removed together with the spring. The
diaphragm is exposed and may be examined for deterioration, cracks, wear etc.
To examine the valve sealing washer, unscrew the self-locking nut from the centre bolt
and remove the spring washer, large stepped washer, and the nitrile rubber seal. The
seal and its seating should be examined for damage. Should the diaphragm require
renewing, this should be carried out at this stage.
When refitting the end covers ensure that the flange faces are clean. Use a new paper
gasket with jointing compound on the inlet cover, (this is at the end opposite to the
diaphragm) and replace in position. Fit the return spring. Push the three bolts through the
cover and the body and refit the diaphragm end cover plate. Replace the nuts and
washers to complete the assembly.
