Dismounting of Pump
- Close the isolation valves in suction and discharge pipes.
- Open the fuses of electricity line fuses coming to motor as they will not carry current
and remove control cable coming to motor from motor terminal box.
- Open the discharge plug under the scroll case and discharge the liquid inside
pump.
- If the liquid inside pump is special, discharge it after taking necessary safety
precautions.
- In liquid oil pumps, open discharge plug in bearing bed and discharge the oil.
-. Remove coupling and other safety guards.
- Remove pump suction and discharge flanges and auxiliary pipe connections and
disconnect pump from pipe system. There is no need in pumps where intermediate
partial clutches are used. In pumps where such kind of clutches are used rotor can
be taken out without separating scroll case from pipe system.
- Separate motor from pump, (not necessary in pumps with coupling)disconnect
pump from frame and take outside.
-Uninstall the bolts which connect roller bearing bed to scroll case.
-Uninstall the bolts which connect seal box to scroll case
- Remove the clutch intermediate part in pumps having coupling. Use the occurred
space and take the bearing group and rotor outside.
-- Remove the clutch part over pump shaft by means of puller. Remove clutch
wedge.
-Uninstall the impellor nut and remove clutch wedge. Use rust solvent if necessary.
Installation of Pump
-. Pump installation operation is made by reverse order of pump dismounting
process.
- Before starting to installation operation, apply lubricious materials such as graphite,
silicone or similar slippery substances over contact surfaces or bolt surfaces. If you
can not find those substances use liquid oil.
- Do not use gaskets which you had removed. Use new ones having same
dimensions. Be careful that new gaskets and O-rings are in same dimensions.
- Start installation from bearing group. Place the bearing into their places over shaft
by using press. Place this part from clutch side towards bed housing. Place the bed
covers from two side. Place the seal box and impellor and tighten the impellor nut.
-Connect the rotor group to body.
-Place the pump over the frame, install the motor and connect suction and discharge
pipes and auxiliary pipes.
