Thrust tube sleeves may be either welded together permanently or alternatively, may have an inner ‘O’ ring
inside the sleeve. Removal of this ‘O’ ring and replacement can be carried out by pulling the two halves
of the thrust sleeve tube apart, prizing out the old ring and fitting with new components supplied.
PUMPS WITH 14” DIAMETER DIAPHRAGMS
All above instructions apply except that the through studs passing through the pump body are in two
sections,and are replaced by bolts screwing into four horizontal bars inset into the pump body.
These bolts must be unscrewed from the top plate and footplate to obtain access to the balls and seats.
Refer to Section 8 for torque figures. Bolts must always be tightened in rotation to ensure that
manifolds are pulled down true and square to avoid subsequent leakage.
