Description
The major components of an 8568 series pump consist of an
air-operated motor and a pump tube. The air motor connects
directly to the double-acting reciprocating pump tube.
These medium-pressure stub pumps (4:1 ratio) are designed
to deliver a range of light weight oils including gear lubricants.
The pump's bung adapter [2 " NPTF (m)] allows installation
directly onto original containers or bulk tanks.
Each model stub pump is also designed to accept a variety
of different length and types of extension tubes. These
extension tubes can also be equipped with a low level cut-off
valve. See Table 2.
The pump can also be installed remotely. In this case the
pump threads directly to the appropriate piping hardware.
