Standard design
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 selfpriming to occur even if the suction pipe is emptied.
A 21- A 31: Close-coupled pumps with the impeller directly supported by the electric motor shaft. Easy-opening front cover,
by unscrewing three hand-nuts, allows quick inspection without disconnecting the inlet and outlet pipes.
A 41 - A 51 - A 66 - A 81: Close-coupled design with separate IEC motor and flexible coupling. Easy-opening front cover, for quick inspection without disturbing the inlet and outlet pipes.
