ROUBLESHOOTING

 

Problem 

Caused by / Conditions 

Solution 

Leaking liquid from washing 
heads. 

Damaged seal in pumping 
head. 

Replace the seal 
immediately. The pump must 
not be used with damaged 
seal. 

Pressure pulsation. 
Pressure sometime suddenly 
decreases. 

Column, injection valve or 
other equipment connected 
after the pump. 

Test if the problem persists 
without any equipment after 
the pump. Then try to connect 
any reliable source of 
hydrodynamic resistance 
(column, reduction valve).
