The CKm 50 self-priming electric pump from the CK series by Pedrollo has a liquid ring.
Recommended for pumping diesel, clean water and chemically non-aggressive liquids for components.
Thanks to its specific operating principle, the liquid ring impeller, the CKm 50 is suitable for irregular and mixed water flow.
Extremely compact, it can be easily installed even in small spaces.
It is an excellent solution thanks to its excellent suction capacity, capable of guaranteeing priming up to 9 metres deep.
