Servicing the Seals
MANIFOLD AND SEAL REMOVAL
1.03 Use a rubber mallet to tap back side of
discharge manifold and separate from inlet
manifold.
1.05 Remove insert adapters from discharge
manifold. Inspect and replace as needed.
1.04 With a helper, remove the discharge manifold
by sliding along the guide studs. Place
discharge manifold on work surface with
seal chambers facing upwards.
1.00 Use a 14 mm hex bit socket with ratchet to
remove the two (2) top outside M16 x 110 HSH
screws on the discharge manifold.
1.01 Hand thread in two (2) M16 x 277 studs
(PN 88902) into the open screw holes.
These studs will assist in guiding the
discharge manifold over the plungers
and evenly distribute the load.
1.02 Use a 14 mm hex bit socket with ratchet to
remove the remaining six (6) M16 x 110 HSH
screws on the discharge manifold.
1.06 Use a 14 mm hex bit socket with ratchet to
remove the two (2) top outside M16 x 50 HSH
screws on the inlet manifold.
1.07 Hand thread in two (2) M16 x 277 studs
(PN 88902) into the open screw holes.
These studs will assist in guiding the inlet
manifold over the plungers and evenly
distribute the load.
Exercise extreme caution when removing the
discharge manifold. It is very heavy and will require
two (2) individuals.
The weight of the manifold or any twisting action
can damage the ceramic plungers.
NOTE: One (1) seal kit is required to repair the pump (see Data Sheet PN 99DAT048).
