Self-priming pumps
4Pages

Standard design AS series sanitary self-priming pumps. A close coupled design with independent shaft support and standard IEC motors. The ability of these pump to maintain a vacuum under varying suction conditions, makes them ideal for applications where the incoming liquid contains gas or air, such as vessel scavenging, the handling of foaming liquids or where the suction pipe is only partially fl ooded. Prior to the fi rst start-up, they must be initially fi lled with liquid; subsequently, liquid remains in the pump, allowing rapid selfpriming to occur, even if the suction pipe is emptied. The construction materials and the quick disassembly design make the AS series particularly suitable for a wide range of applications. All CF-3M 1.4404 / AISI 316L stainless steel parts. Investment cast components with electro-chemical polishing. Stainless steel adjustable feet. Seals: Mechanical seals with seats to EN 12756, ISO 3069 standards. Single internal mechanical seal Flushed mechanical seal Double fl ushed mechanical seal Elastomers (certifi ed to FDA): EPDM Fluorocarbon (Viton) Silicone P.T.F.E. (FEP) Connections: DIN - SMS - IDF - BS / RJT - DS - CLAMP and EN 1092-1 PN16 fl anges to suit most international standards. Applications AS series pumps incorporate design features and material technologies that enable them to fulfi l a wide range of operational requirements within the food, beverage, dairy, pharmaceutical and chemical industries. They are especially suited for clear low viscosity fl uids: CIP solutions, water, juices, wine, spirits, chemicals and pharmaceutical media, in CIP scavenge/return and tank emptying duties.
