14.3 Operation supervision

 

 

Depending on the disposability of personnel and on the importance of the pump, we recommend the following supervision. 

In case of any irregularity, the maintenance supervisor should be called immediately.

 

 

14.3.1 Weekly supervision

 

 

Check:  

 

a)  Operating point of the pump 

b)  Electric motor consumed current and network voltage 

c)  Suction pressure 

d)  Vibrations and irregular noises 

e)  Oil level 

f)  Packing leakage 

 

14.3.2. Monthly supervision 
 

Check:  

 

a)  Oil change interval. Consult chapter 15.2 

 

14.3.3. Semestral supervision 
 

Check:  

 

a)  Fixing bolts on pump, driver and base 

b)  Alignment of the motor-pump assembly 

c)  Coupling lubrication (if any) 

 

14.3.4 Annual supervision 
 

a)  Disassemble the pump for maintenance. After cleaning, inspect condition of : ball and roller bearings (very carefully), 

radial seal rings, gaskets, o-rings, impellers, internal areas of the volute casing (check also thickness), wear areas and 

coupling. 

 
14.4 Shutdown procedure 
 

Follow in sequence these instructions: 

 

a)  Shut off pump discharge valve 

 

b)  Turn off the driver and observe the pump assembly stop, gradual and smoothly 

 

c)  Close the suction valve (if any) 

 

d)  Close the auxiliary pipe lines (if there is no contraindication of the mechanical seal manufacturer)
