CLEANING
DISASSEMBLY
WARNING
Before servicing the pump, disconnect electrical power
source, carefully relieve all pressure, and drain all fluids
from the pump and connected piping.
It is necessary to disassemble parts of your pump for cleaning and sanitizing. The extent of
disassembly will depend on the application and the type of seal used in your pump. For pumps
equipped with the “groove in shaft” design, it is not necessary to disassemble if used in a clean-in-
place installation.
To disassemble:
1.
Disconnect the suction and discharge piping.
2.
Turn the wingnut on the clamp assembly until tension on the clamp saddle is relieved.
3.
Open the saddle and remove the casing.
4.
On pumps with the floating impeller retainer:
a. Rotate the impeller until the retainer is in a horizontal position.
b. Push back on the impeller and center the retainer in the shaft.
c. Slide the impeller forward and remove it.
5.
On pumps with threaded shaft and castellated nut, remove cotter pin and turn castellated nut
in counterclockwise direction, and remove washer and impeller. Pumps equipped with
packing glands do not require further disassembly for cleaning.
Refer to the
Seal Servicing section of this manual for disassembly and reassembly of the seal
installed in your pump.
