The "PA-AM" pumps have metal parts in product contact made from AISI 316 stainless steel. Mirror polished both internally and externally. With the "long" version, it is possible to immerse the pumping cylinder and inlet port directly into drums or vats. The powerful double effect pneumatic motor, protected by a stainless steel shroud, can cover a wide range of performances for flow rate and pressure. The components are assembled with clamps for quick and easy disassembly for periodical inspection and cleaning. Usually the pumps are light and easy to handle. For larger, heavier models special trolleys are available to secure the pumps to vertical lifts or to clamps which secure the pump to a container during emptying or for mounting on a wall.
