Description
The major components of the stub pumps in
the model series consists of an air-
operated motor and a pump tube. The air
motor connects directly to a double-acting
reciprocating pump tube. These low-
pressure stub pumps (: ratio) are designed
to deliver all grades of oil.
Pump extensions
Extensions that screw directly into the
pump’s fluid inlet allow the pump to
accommodate different size drums and
tanks. Extensions are accessory items and
are not included with the pump.
See Accessories table, page 7.
