Application CIP self-priming pump uses acid resistant stainless steel(AISI316) as the main material ofthe pump body, possessingthe character of resisting the erosion of acid and alkaliand going well with the requirements of food sanitary.The self-oriming pump can inhale the liquids with air orfoams and ir can also work well even in the condition ofonly air So it is the capacitive pump with the superior characters than centrifugal pumps. It is broadly used inimbibition when liquid surface is lower than the pump. E.g.it can inhale the milk from the barrel; It can also be usedin the CIP as the returning pump for cleaning tank,mechanical sealed ad internal flow. The temperature of the absorbing material can not be higher tan 100'C.
