REASSEMBLY HINTS & TIPS
ASSEMBLY:
Upon performing applicable maintenance to the air distribu-
tion system, the pump can now be reassembled. Please
refer to the disassembly instructions for photos and parts
placement. To reassemble the pump, follow the disassem-
bly instructions in reverse order. The air distribution system
needs to be assembled first, then the diaphragms and finally
the wetted path. Please find the applicable torque speci-
fications on this page. The following tips will assist in the
assembly process.
• Clean the inside of the center section shaft bushing to
ensure no damage is done to new seals.
• Stainless bolts should be lubed to reduce the possibility
of seizing during tightening.
• Level the water chamber side of the intake/discharge
manifold to ensure a proper sealing surface. This is most
easily accomplished by placing them on a flat surface
prior to tightening their clamp bands to the desired
torque (see this page for torque specs).
• Be sure to tighten outer pistons simultaneously on PTFE-
fitted pumps to ensure proper torque values.
• Place one liquid chamber on its side and align center
section with chamber using alignment marks made during
disassembly. Push down on diaphragm assembly until
diaphragm is inverted. Place opposite liquid chamber on
center section and align.
• Position valve balls, seats, and o-rings in discharge
manifold. Place vertical through discharge manifold with
threads pointing up. Install washer and start threads of
bolt (about 1-1/2 turns).
•
Place center section and liquid chambers on intake mani-
fold.
•
Position discharge manifold and bolt assembly on liquid
chambers. Ensure proper alignment of mating surfaces
between liquid chambers and manifolds before tightening
bolts.
• Apply a small amount of Loctite 242 to the steel bore of
the shaft from the diaphragm assembly.
UL LISTED PUMPS
ASSEMBLY:
Upon performing applicable maintenance to the air distribu-
tion system, the UL pump can now be reassembled. Please
refer to the disassembly instructions for photos and parts
placement. To reassemble the pump, follow the disassem-
bly instructions in reverse order. The air distribution system
needs to be assembled first, then the diaphragms and finally
the wetted path. Please find the applicable torque speci-
fications on this page. The following tips will assist in the
assembly process.
• Clean the inside of the center section shaft bushing to
ensure no damage is done to new seals.
• Stainless steel bolts should be lubed to reduce the possi-
bility of seizing during tightening.
• Level the water chamber side of the intake/discharge
manifold to ensure a proper sealing surface. This is most
easily accomplished by placing them on a flat surface prior
to tightening their vertical bolts to the desired torque.
• Apply a small amount of Loctite 242 to the steel bore of
the shaft from the diaphragm assembly.
• Be sure to tighten outer pistons simultaneously on PTFE-
fitted pumps to ensure proper torque values.
• Place one liquid chamber on its side and align center
section with chamber using alignment marks made
during disassembly. Push down on diaphragm assembly
until diaphragm is inverted. Place opposite liquid cham-
ber on center section and align.
• Position valve balls, seats, and o-rings in discharge mani-
fold. Install vertical bolts through discharge manifold
with threads pointing up. Install washer and start threads
of bolt (about 11 turns).
• Place center section and liquid chambers on intake
manifold.
• Position discharge manifold and bolt assembly on liquid
chambers. Ensure proper alignment of mating surfaces
between liquid chambers and manifolds before tighten-
ing vertical bolts.
• After vertical bolts are tightened, install two (#1 & #2)
of the four jumper wires to the front-right vertical bolt.
Install grounding tag. Install jam nut onto vertical bolt.
• Route #1 jumper wire to back of pump and attach to
liquid chamber with 1/4-20 fastener.
• Route #2 jumper wire to the top of the center section.
• Install #3 jumper wire to the muffler plate using 1/4-20
fastener. Ensure the small eyelet of jumper wire is used
at this location.
• Route #3 jumper wire from muffler plate to the top of the
center section. Using one 1/4-20 fastener, install the #3
jumper wire, then install the #2 jumper wire over the top
of the #3 jumper wire. The #2 jumper wire should have
the small eyelet for use in this connection.
• Install #4 jumper wire to the front-left vertical bolt. Install
jam nut onto vertical bolt.
• Route the #4 wire to front of pump (left liquid chamber)
and attach to liquid chamber with 1/4-20 fastener.
