the diaphragm (O) into the Pump body.
5. INSTALLING NEW DIAPHRAGMS: Clean well the threaded hole of the piston (Q). Install the
diaphragm bolt (L) and washer (M) into the new diaphragm (O). Install this assembly to the piston
(Q). Use Loctite 243 thread locker o equivalent on the diaphragm bolt (L). Then torque to the
recommended specifications (see page 19). Now rotate crankshaft (N) to bring the piston (Q) and
diaphragm (O) to the bottom of its stroke. Then seat the outside edge of the diaphragm (O) into the
Pump body.
6. HEAD INSTALL: When reinstalling the Pump head (B) it is very important to make sure that the
check valves are installed correctly. For each cylinder there are two valves, one valve lets the fluid
flow into to the head, the other valve lets the fluid flow out of the head. PAY VERY CLOSE
ATTENTION TO THIS. After having correctly positioned the Pump head (B), tighten the screws (A)
with the proper torque (see page 19).
7. INSTALLING PULSATION DAMPENER DIAPHRAGM: Bleed off the air in the chamber using the
air-valve (G) on the dampener, then remove the cover bolts (E), cover (D) and diaphragm (C), install
correctly the new diaphragm (C). Reinstall cover (D) and tighten the screws (A) with the proper
torque (see page 19). Recharge dampener with air according to UDOR specifications at page 13.
8. REFILL PUMP CRANKCASE: Re-mount the oil drain plug (T). Fill Pump with SAE 15W-40 OIL to
recommended mark on the oil reservoir (H) or on the sight glass (S). Rotate the crankshaft (N) while
filling to eliminate air pockets. Re-mount the oil fill cap (F) or the oil fill plug (R).
9. INITIAL START UP: Start the Pump with the outlet line at “0” pressure; after about 5 minutes at “0”
pressure you may increase the outlet pressure and make a few cycles of pressure on/off. This will
evacuate any remaining air pockets in the crankcase. Turn Pump off and re-check oil level. Refill as
necessary to proper oil level.
IMPORTANT: During initial start up, monitor the oil color. If it turns milky white, the diaphragms were
not seated correctly.
9.2 LUBRICATION
The Pump is supplied with the correct amount of lubrication oil (see table on page 17).
Periodically check the oil level in the Pump through the oil level indicator.
Use OIL type SAE 15W-40 or equivalent. Here are some recommended types of oil:
BRAND TYPE
AGIP F.1 Supermotoroil 15W-40
BP Vanellus C 15W-40
CASTROL GTX 15W-40
ESSO Uniflo 15W-40
MOBIL Super M 15W-40
SHELL Rimula R4 15W-40 / Helix Super 15W40
TOTAL Rubia 15W-40 / Quartz 5000 15W-40
The oil is to be changed by draining it through the dedicated bottom discharge cap and strictly with
the Pump stopped.
The oil level could vary during priming ; then it will stabilize when the system is pressurized. If the oil
level gets lower during the first few hours of the pump’s operation , it could be normal. Simply refill .
If instead , the oil level changes considerably after several hours of operation, the pump’s
diaphragms might be damaged or there might be restrictions along the suction line.
DO NOT START THE PUMP IF THERE IS NO OIL IN THE PUMP!
During maintenance, you are recommended to:
- Use and wear suitable personal protection equipment (i.e. gloves).
- Wait for the machine to cool down and to have stopped completely.
