7. TO CHANGE VALVE RUBBERS:
A. Remove suction and discharge connections and
remove valve rubbers.
B. Place new valve rubber between weight and binder
and insert and tighten 2 screws that hold them together.
Tighten fi rmly but not so rubber is distorted, causing
poor seating.
C. Install fl apper valve assembly onto the fl ap valve seat.
Tighten the two bolts holding the clamp bar and fl ap
valve to the seat. DO NOT overtighten so as to distort
the fl ap valve.
8. Diaphragm pumps will handle fl uids containing
considerable solids, however if mixture is too heavy to
be pumped, liquid must be added until it becomes
suffi ciently fl uid for pumping.
9. Neoprene and other rubbers can be furnished for the
diaphragm and valve rubbers when pumping fl uids
containing considerable oils, greases or chemicals.
10. DRIVE GEAR AND PINION:
Paint grease on the drive gear and pinion whenever the
gear mesh looks dry. Use an Exxon Ronex MP grease
or equal.
SECTION E: TROUBLE SHOOTING
If your pump does not prime or operate properly, check the
following:
1. Pump may be too high above or far from water.
2. Leaks in suction hose or hose connection to pump.
Check if hose inner lining has loosened. If loose, pump
suction will cause lining to collapse and block hose.
3. Valves may not be seating properly due to accumulation
of residue or wear. Pour water in suction and discharge
chambers to help seal valves.
4. Check diaphragm for breaks or leaks
5. Make sure that end of suction line is in position to allow
water to enter; it may be buried in muck or blocked in
other ways.
