Self-priming pumps are also known as CIP return pumps,the pump part of the materials,are acid-resistant stainless steel (AISI  316),acid and alkali resistance properties,is particularly significant,in line with food hygiene requirements.

Characteristics better than centrifugal pump means that it can absorb liquid mixed with air or foam,and can conduct self-sucking when there is only air.This pump belongs to positive displacement pump and is widely used to suck material when liquid level is below pump. For example,it can suck milk from milk can,or can be considered as pullback pump of cleaning tank in automatic CIP cleaning system. Mechanical seal is internal installation inward flow type,and sucked material temperature is not higher than 120℃ .
