Description
Major components of the 8568-A4 pump
consist of an air-operated motor and pump
tube The air motor connects directly to a
double-acting reciprocating pump tube
This low-pressure stub pump (4:1 ratio) is
designed to deliver a range of light weight
oils including gear lubricants Pump's
2 in NPTF (e) bung adapter allows
installation directly onto original containers
or bulk tanks
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 (→ Table 2, page 7)
Pump can also be installed remotely In
this case pump threads directly to
