WARNING:
Refer to Fig. 1.
a) PREPARING THE ENGINE: Follow the engine manufacturer's
instructions before operating.
b) PRIMING THE PUMP: Remove the priming plug and fi ll the
casing with the same liquid that you will be pumping and
replace plug. If the pump is below the level of the liquid that
will be pumped (fl ooded suction), the pump will automatically
fi ll up when the valves are open. Then start the pump.
NOTE: DO NOT OPERATE THIS PUMP DRY!
c) START-UP: In a 'fl ooded suction' situation, the pump will
discharge the liquid almost immediately. If the suction line is

a) ENGINE: Refer to the engine manufacturer's instructions for
any maintenance requirements.
b) FLUSHING: If you are pumping chemicals, fertilizers or corrosive
liquids, fl ush the pump after each use. Remove the drain and
priming plugs and fi ll the casing several times with clean water.
Refer to Fig. 2.
DISASSEMBLY:
1) Drain the pump (see Draining under Maintenance).
2) Disconnect the pipes/hoses.
3) To remove the casing (1) remove the 4 bolts from the
adapter.
4) To remove the impeller (2), use a rubber mallet to tap it loose
and unscrew the impeller in a counter-clockwise direction.
5) To remove the seal (8), simply pull it off of the shaft. The
sleeve (10) will slide off with it.
6) Remove the adapter (6), by removing the 4 bolts.
7) To remove the ceramic seat (9), press it out from the backside
of the adapter with your thumbs.
8) Remove the rubber cup (4) from the adapter.
9) DO NOT REMOVE THE FLINGER (11) unless it needs to
be replaced.
REASSEMBLY:
1) Clean all parts thoroughly before reassembly.
2) Apply liquid soap to the outer surface of the rubber cup (4)
on the stationary seat (9). Insert the stationary seal seat into
the seal adapter plate. Make sure that the smooth face of the
ceramic seat is facing towards the front of the pump. Push
this assembly into the adapter, using hand pressure only.
OPERATION - PRIMING THE PUMP
DO NOT RUN THE PUMP BEFORE PRIMING IT, SINCE THE SEAL AND IMPELLER COULD BE
PERMANENTLY DAMAGED.
These pumps can also be used for basic dewatering purposes.

above the liquid level being pumped, it will take a few minutes
to lift the water to the casing and then to discharge it. If the
suction line is quite long, the pump may overheat before the
liquid in the suction line reaches the pump. In this case, turn
the pump off and drain the casing. Wait a few minutes for
the seal in the pump casing to cool down.Then replace the
drain plug and refi ll the casing with the same liquid that will be
pumped. Replace the priming plug and restart the pump.
WARNING
If the overheated casing is fi lled while hot, damage to the seal
will occur.

MAINTENANCE
c) DRAINING: If the pump is subject to freezing temperatures,
drain the pump by removing the drain plug and priming plug.
After liquid has drained, run the pump for a few seconds to
get the last liquid out of the impeller. Make sure the suction
and discharge lines are free of liquid.
REPAIR
3) Assemble the adapter (6) and handle (5) onto the engine
using the bolts and washers. Make sure that the fl inger (11)
is on the shaft.
NOTE: There may be more than one position that the
IMPORTANT: Be careful not to damage the ceramic seat or
shaft, when assembling the adapter to the engine.
4) Replace the Seal:
- The sleeve (10) may have a chamfer on the inside diameter
at one end only, or at both ends. If the chamfer is only on
one end, the chamfer end must be towards the engine. Slide
it onto the shaft.
- Make sure both faces of the seal are clean, then slide seal
(8) onto the sleeve.
5) Screw on the impeller (2), clockwise.6) Replace the gasket
(3) and the washers. Then assemble the casing onto the
adapter. Use thread locking / sealing compound on casing
bolts to prevent leaks.
PRECAUTION: Check to see that the impeller rotates freely
7) Reconnect the suction and discharge lines. Use a thread
compound and make sure that the connections are tight.
