FLYGT MP-3067 PUMP 

 

Safety Precautions 

Before  starting  work  on  the  pump,  make  sure  that  the  pump  is  isolated  from  the  power  supply  and  cannot  be 
energized. 
 
NOTE!  This applies to the control circuit as well. 
 
The following points are important in connection with work on the pump: 

-

 

Make sure the pump has been thoroughly cleaned. 

-

 

Observe good personal hygiene. 

-

 

Beware the risk of infection. 

-

 

Follow local safety regulations. 

 
The pump is designed for use in liquids which can be hazardous to health.  In order to prevent injury to the eyes and 
skin, observe the following points when working on the pump: 

-

 

Always wear goggles and rubber gloves. 

-

 

Rinse the pump thoroughly with clean water before starting work. 

-

 

Rinse the components in water after disassembly. 

-

 

The  oil  housing  may  be  under  pressure.    Hold  a  rag  over  the  oil  casing  screw  (oil  plug)  and  the 
inspection screw to prevent splatter. 

 
Proceed as follows if you get hazardous chemicals in your eyes: 

-

 

Rinse immediately in running water for 15 minutes.  Hold your eyelids apart with your fingers. 

-

 

Contact an eye specialist. 

On your skin: 

-

 

Remove contaminated clothes. 

-

 

Wash your skin with soap and water. 

-

 

Seek medical attention, if required. 

 
Make sure the pump cannot roll or fall over and injure people or damage property. 
 

Inspection 

Regular inspection and preventive maintenance ensure more reliable operation. 
 
The pump should be inspected at least once a year, but more frequently under sever operation conditions. 
 
Under normal operating conditions, the pump should have a major overhaul in a service shop at least every third 
year for permanent installation and every year for portable pumps. 
 
If the pump is new or if the seals have been replaced, inspections is recommended after one week of operation. 
 
Regular check of the condition of the lifting handle and chain is important. 
 

Inspection of hot water applications 

Pumps in hot water applications shall undergo inspection or overhaul at a service shop as follow, depending on the 
time they have been submerged in the hot water:
