Pumps with a triple lip seal: fitting the rear liner
Pumps with a stainless steel seal housing for a triple lip seal:
fitting the sealing system
l Push the shaft sleeve fitted with the seal housing over the shaft and into
position, the chamfered, lip-seal end of the shaft sleeve first. The seal
housing’s pins (arrowed) must be upward and central. The shaft sleeve is a
tight push fit. Be sure to push it all the way home. The shaft sleeve has an
alignment lug inside it (ringed) which must be aligned with the shaft splines.
l Push the shaft sleeve into the seal housing (with the lip seals)
l Push the rear liner into position below the shaft sleeve, pushing evenly at both
ends so that it does not jam. The anti-rotation pins within the pump housing
(arrowed) guarantee that the liner is properly positioned. The two liners are
identical.
