Lubricant Pump
TM
9670
DESCRIPTION
Model 9670 Lubricant Pump is designed to pump
light to heavy oils directly from the original container.
This design features a 10:1 material-to-air pressure
ratio allowing for the pump to also be used when
pumping in longer systems. Maximum operating air
pressure of 150 psi would, therefore, create 1500 psi
of material pressure.
328304 ❋

▲
328030 ❋
The pump's double-action, reciprocating pump tube
is powered by an air-operated spool valve motor
providing a constant delivery of material on both the
upstroke and downstroke.
Material Outlet
(3/8" NPTF)
▲
Used with an extension (not included), the pump can
be mounted directly onto a remote tank or drum
having 2" bung threads. Furthermore, the pump can
be mounted on a wall bracket and used with a
suction hose.
NOTE: For sales information on extension, wall
bracket, and suction hose, contact your nearest
Regional Alemite Sales Office.
