Maintenance 

7.1. 

 

 GENERAL CONSIDERATIONS 

This  pump,  just  like  any  other  machine,  requires  maintenance.  The  instructions  contained  in  this  manual  cover  the 
identification  and  replacement  of  spare  parts.  The  instructions  are  aimed  at  maintenance  personnel  and  those 
responsible for the supply of spare parts.  

 

 

 

Carefully read Chapter 8. 

H

Technical Specifications

 

All replaced material should be duly disposed of/recycled according to the directives in force in each area. 

 

ALWAYS disconnect the pump before beginning any maintenance work. 

 

7.1.1.  

 

Check the mechanical seal 

Periodically check that there are no leaks around the shaft. If leakage is detected through the mechanical seal, replace 
it following the instructions in the section Assembly and Disassembly. 

 

7.2. 

 

STORAGE 

Before storing the pump it should be completely drained. Prevent as far as possible exposing the parts to excessively 
humid environments. 

 

7.3. 

 

CLEANING 

 

 

The use of aggressive cleaning products such as caustic soda and nitric acid may burn the skin. 

 

Use rubber gloves during the cleaning process. 

 

 

Always use protective goggles. 

 

7.3.1.  

 

CIP (Clean-in-Place) cleaning 

If  the  pump  is  installed  in  a  system  with  a  CIP  process,  its  removal  will  not  be  required.  If  an  automatic  
cleaning process is not available, disassemble the pump as indicated in the section 

Assembly and Disassembly

 

 

Cleaning solutions for CIP processes. 

 

Only use clear water (chlorine-free) to mix with the cleaning agents: 

 

a) Alkaline solution:    

1% by weight of caustic soda (NaOH) at 70ºC (150ºF) 

 

                                     1 kg NaOH + 100 litres of  water = cleaning solution 

or 

                         2.2 litres of 33% NaOH + 100 litres of  water = cleaning solution 

 

b) Acid solution:

  

   0.5% by weight of nitric acid (HNO

3

) at 70ºC (150ºF) 

 

                             0.7 litres of  53% HNO

3

 + 100 litres of  water = cleaning solution
