Medium-Pressure Stub Pump
Description
The major components of the model 9668 stub pump consists of
an air-operated motor and a pump tube. The air motor connects
directly to the double-acting reciprocating pump tube.
This medium-pressure stub pump (5:1 ratio) is designed to
deliver all grades of oil. The pump’s bung adapter [2 " NPTF (m)] *
allows installation directly onto original containers or bulk tanks.
Pump Extensions
Extensions that screw directly into the pump’s material inlet
allow the pump to accommodate different size drums and tanks.
Extensions are accessory items and are not included with the pump.
