Linning process is Wolong’s Patent
Pump casing and cover are made of HT200 iron lining with PFA, PTFE, impeller made by WCB wrapped by PTFA, PTFE, which grantee this type centrifugal pump could widely used in corrosive application and wear well.
Reliable mechanical seal  
Shaft seal is outside seal, stationary seal is alumina ceramic ( 99.9%), rotating seal is PTFE filling material or according to customer request.
Advantage: High corrosive, well leakproof, easy assembly and maintenance
