Assembling the SPS 100
During assembly, check that all O-rings are properly positioned before fitting each component, and that
all components are clean and lubricated.
Fitting the seal housing
The two versions of the SPS 100 pump seal housing: left,
where no static flushing system is fitted; right, where a
static flushing system is fitted
•
Push the reassembled seal housing into position, castellations first. Make sure it is pressed all the
way home. This can be done using the special tools as pushers, or using a special cylindrical tool
which is available from MasoSine. Note: If a static flushing device is to be fitted, align the threaded
sockets on both sides of the seal housing vertically, so they are central to the top hole in the
bearing housing. See "The static flushing device" on page 83.
Fitting the static face and the mechanical seal—SPS 100 pumps with a single mechanical seal
•
Check that the static face’s O-ring is properly positioned and that the O-rings either side of the
mechanical seal are properly positioned.
