The A series self-priming pumps are built enbloc. According to the capacities, the rotor can be directly supported by the motor shaft or the motor separated and the flexible coupling. Chemical polishing and quick disassembly construction makes them particularly suitable for all the applications of food industry. All the parts in contact with the product are built in AISI 316 steel.

The ability to maintain a vacuum under changing suction conditions makes A Series pumps ideally suited for scavenge duties and applications where the inlet pipework is only partially filled, or where the incoming liquid includes entrained air or gas. The construction materials and quick disassembly design make them particularly suitable for a wide variety of applications.

They must be initially filled with liquid for the first start-up; afterwards, a small liquid reservoir remains to enable rapid self-priming to occur even if the suction pipe is emptied.
