Technical  Specifications

.  INOXPA  will  not  be  liable  for  improper  use  of  the 

equipment. 

 

 

NEVER touch the pump or the lines if hot liquids are being pumped. 

 

5.1.1.  

 

Checks before starting the pump 

 

·

 

Completely open the shut-off valves on the suction and discharge lines. 

·

 

If liquid does not flow towards the pump, fill it with the liquid to be pumped. 

 

 

The pump must never turn dry. 

 

·

 

Check that the direction of rotation of the motor is correct. 

 

5.1.2.  

 

Checks when starting the pump 

 

·

 

Check that the pump is not making any strange noises. 

·

 

Check if the  absolute inlet  pressure is sufficient  to prevent cavitation in  the  pump. Check the curve to obtain the 

minimum required pressure above the vapour pressure (NPSHr). 

·

 

Control the discharge pressure. 

·

 

Check for leaks in the sealing areas. 

 

 

A shut-off valve shall not be used to regulate the flow in the suction line. All shut-off valves must be fully 
open during operation. 

 

 

Control the motor consumption to prevent an electrical overload. 

   

 

Reduce  the  flow  rate  and  the  electrical  power 
consumed by the motor: 

  

·

 

by regulating the pump's discharge flow. 

·

 

by decreasing the motor speed. 

 

 

 

Use special protection when the sound pressure in the operation area exceeds 80 dB(A).
