Self-priming vs. standard centrifugal pump comparsion

The CTS pump is a great alternative to our standard CT pumps when the self-priming ability is needed. 
By replacing only one element -  the casing  with a self-priming chamber – we can achieve various advantages for our pump. 
The pump can now suck the liquid form a lower level than it is positioned or handle liquids with high content of air. 
The construction of the pump chamber ensures that there is always enough liquid left inside in order to prime the pump after stoppage.
