4.0 Disassembly and assembly
4.1 Assembly of head kit (pump without motor) to IEC-motor
See drawing sections 5.1 and 5.5.
1) Clean the motor shaft and make sure that the surface does not have any cuts or marks.
2) Put the pump and motor shaft together by using a plastic hammer or equivalent. Make sure
not to damge the pump shaft.
3) Clean the surface area of the rotating seal part and assemble to the pump shaft.
4) Bolt the flange to the motor.
5) Clean the surface area of the stationary seal part, which is assembled in the pump body.
6) Slide the complete pump head kit onto the flange, taking care not to damage the seals.
Twist the pump back and forth to get the shaft connected correctly in the impeller. In
case of necessity, pull out the impeller and assemble the pump body separately.
7) Tighten the cap screws according to section 2.9.
4.2 Disassembly of impeller and shaft seal
See drawing sections 5.1, 5.3, 5.5 and 5.7.
1) If check valves are installed, close the valves on both sides of the pump and drain the
pump.
2) Remove the front cover (2) and gasket.
3) Remove the impeller (3) from the pump
body (4) by using suitable pliers or two
levers. Take care not to damage the
pump body.
4) Separate the pump body from the
pedestal/flange (6). Check for wear
inside the pump body and replace
wearing parts if necessary (bronze
pumps only).
5) Press out the seal seat from the pump body. Remove the seal assembly from the shaft.
6) Inspect and clean all parts which will be reused.
4.3 Assembly of shaft seal and impeller
See drawing sections 5.1, 5.3, 5.5 and 5.7.
1) Slide the rotating seal part onto the shaft with a twisting movement, and press the
stationary seal part into the pump body. Lubrication with soap solution (for foodstuff
applications use appropriate food grease) will ease the assembly.
2) Bronze pumps: Change wear plate (22) and cam (21) if worn. Before assembling, apply
sealing compound onto cam, e.g. Permatex Form-a-gasket No. 3, and cam screw, e.g.
Permatex Form-a-gasket No. 2.
