Franklin Electric FBSE Series Owner's Manual page 3

DISASSEMBLY:
1) Drain the pump (see DRAINING).
2) Disconnect the pipe/hoses.
3) To remove the casing (2), remove the nuts (on a FSBEF-
150, -200, -300, remove the bolts) from the adapter.
4) To remove the impeller (3), remove the cap off of the back
end of the motor and insert a screwdriver into the slot on
the shaft. Unscrew the impeller, or the bolt (1) in a counter-
clockwise direction.
5) To remove the seal (8), simply pull it off of the shaft. On a
FBSEF-500, -750, the sleeve (11) will come with it.
6) To remove the adapter (6), remove the bolts and pull the
adapter off.
CAUTION: Be careful not to damage the motor shaft (7)
when removing the adapter.
7) To remove the ceramic seat (9), press it on from the
backside of the seal plate.
8) Remove the rubber cup (5).
9) Do not remove the flinger (10), unless it needs to be
replaced.
REASSEMBLY:
1) Clean all parts thoroughly before reassembly.
Refer to Fig. 3, to reassemble the following items.
2) Insert the ceramic seat (9) into the rubber cup (5). Make
sure that the smooth face of the ceramic seat is facing
towards the front of the pump. Oil the rubber cup and push
this assembly into the adapter (6), using hand pressure
only.
3) Bolt the adapter assembly onto the motor. Make sure that
the flinger (10) is on the shaft.
CAUTION: Be careful not to damage the ceramic seat
or shaft when reassembling sleeve to the motor.
4) Slide the sleeve (11), except for the FSBEF-150, -200, -300,
and the seal (8) onto the shaft. Insert the key into the slot in
the sleeve.
5) Reassemble the impeller (3).
6) Replace the gasket (4) and the washers. Then assemble
the casing (2) onto the adapter.
PRECAUTION: Check to see that the impeller rotates
freely in the casing.
7) Reconnect the suction and discharge lines. Use a thread
compound and make sure that the connections are tight.
a) Pump Fails to Prime or Primes Slowly:
1) Leaks in the suction line.
2) Loose gasket connection due to shrinkage of the gasket.
3) Collapsed or clogged suction line.
4) Not enough water in the casing for priming.
5) Suction lift is too great.
b) Reduced Pressure or Capacity:
1) Partially collapsed or clogged suction hose.

Clogged impeller.
Leaks in the suction line.
Strainer or end of suction hose is not properly submerged.
Suction line is improperly installed, resulting in air pockets
in the suction line.
Suction lift is too great (the greater the suction lift, the
lower the capacity and pressure).
Worn parts, such as the impeller or the pump casing.
