FLUSHING PROCEDURES FOR CHEMPUMP PRODUCTS

THE FOLLOWING FLUSHING PROCEDURES ARE REQUIRED TO ALLOW FOR MAXIMUM REMOVAL OF PROCESS FLUIDS.

A.

COMPLETE PUMP

A1)

WITH THE SUCTION FLANGE DOWN, INTRODUCE AN APPROPRIATE NEUTRALIZING FLUID
THROUGH THE DISCHARGE FLANGE.  FLUSH THE PUMP IN THIS MANNER FOR A SUFFICIENT
TIME TO ALLOW FOR THE REMOVAL OF ALL PROCESS FLUID.

A2)

AGAIN, WITH THE SUCTION FLANGE DOWN, REMOVE THE CIRCULATION LINE (AND FITTING IF
NECESSARY) AND INTRODUCE AN APPROPRIATE NEUTRALIZING FLUID TO THE REAR OF THE
PUMP.  FLUSH THE PUMP IN THIS MANNER FOR A SUFFICIENT TIME TO ALLOW FOR THE
REMOVAL OF ALL PROCESS FLUID.  ALSO FLUSH THE CIRCULATION LINE AND/OR HEAT
EXCHANGER TUBING, AS REQUIRED.

A3)

AFTER FLUSHING AS SPECIFIED ABOVE, REMOVE AS MUCH OF THE NEUTRALIZING FLUID AS
POSSIBLE USING COMPRESSED AIR OR INERT GAS.

B.

G and J-SERIES STATOR  ASSEMBLY (if equipped with a relief valve ): IF A STATOR LINER RUPTURE IS
SUSPECTED, FOLLOW THIS SECTION TO FLUSH THE STATOR CAVITY.  

CAUTION:  IF THIS STEP IS

FOLLOWED, THE MOTOR MUST BE REWOUND.

B1)

REMOVE THE RELIEF VALVE.  INSERT A SCREWDRIVER INTO THE RELIEF VALVE ADAPTER
AND PRY THE LISK FILTER TO ONE SIDE.  REMOVE THE CONNECTION BOX FROM THE LEAD
NIPPLE AND CHIP AWAY THE POTTING COMPOUND FROM THE LEAD NIPPLE.

B2)

POSITION THE STATOR ASSEMBLY WITH THE LEAD NIPPLE DOWN AND INTRODUCE AN
APPROPRIATE NEUTRALIZING FLUID TO THE RELIEF VALVE ADAPTER.  THE FLUID WILL EXIT
THROUGH THE LEAD NIPPLE.  FLUSH THE STATOR CAVITY IN THIS MANNER FOR A SUFFI-
CIENT TIME TO ALLOW FOR THE REMOVAL OF ALL PROCESS FLUID AND STATOR OIL.

B3)

REMOVE AS MUCH OF THE NEUTRALIZING FLUID AS POSSIBLE BY PURGING THE STATOR
CAVITY WITH COMPRESSED AIR OR INERT GAS FOR 3 - 5 MINUTES.

C.

NC and LE-SERIES STATOR  ASSEMBLY (no relief valve):  IF A STATOR LINER RUPTURE IS
SUSPECTED, FOLLOW THIS SECTION TO FLUSH THE STATOR CAVITY.  

CAUTION:  IF THIS STEP IS

FOLLOWED, THE MOTOR MUST BE REWOUND.

C1)

DRILL A HOLE THROUGH BASE CRADLE MOUNTING HOLE LOCATED IN REAR END BELL, DRILL
THIS HOLE JUST DEEP ENOUGH TO BREAK THROUGH END BELL. DRILL A SECOND HOLE
THROUGH STATOR LINER ON OPPOSITE END OF STATOR.

C2)

POSITION THE STATOR ASSEMBLY WITH REAR END BELL UP AND INTRODUCE AN APPROPRI-
ATE NEUTRALIZING FLUID THROUGH DRILLED HOLE IN REAR END BELL. THE FLUID WILL EXIT
THROUGH THE DRILLED HOLE ON OPPOSITE SIDE.  FLUSH THE STATOR CAVITY FOR A
SUFFICIENT TIME TO ALLOW FOR THE REMOVAL OF ALL PROCESS FLUID.

C3)

REMOVE AS MUCH OF THE NEUTRALIZING FLUID AS POSSIBLE BY PURGING THE STATOR
CAVITY WITH COMPRESSED AIR OR INERT GAS FOR 3 - 5 MINUTES.
