Port Name Function
DA Single-acting model pumps:
(Double Port is fitted with a plastic vent orifice plug so
that air can be exhausted on piston return
stroke.
Double acting model pumps:
Port has air or hydraulic supply connected to it.
Fluid directed to this port causes the pump to
retract to the loading position.
GAUGE Port for attaching a pressure gauge to indicate
pump output pressure. This port is common to
the LUBE OUT port.
IND Port for attaching a blowout or pressure
indicating assembly. This port is common to
the LUBE OUT port.
SYS FILL Port for attaching an inlet check valve. This
allows the lubrication lines to be filled by an
outside source of lubricant so that the pump
does not cycle excessively when filling the
system.
LUBE OUT Port that the system being lubricated is
connected to. An outlet check valve is installed
here.
SA Port has a pneumatic or hydraulic supply
(Single source connected to it. Fluid directed to this
Acting) port causes the pump to dispense.
TEST Port is used for bleeding air out of pump. Back
out setscrew one or two turns while pump is in
the dispense stroke. Close setscrew when
pump is on return stroke to prevent air from
being sucked in. Repeat process until air-free
lubricant comes from vent hole.
LUBE IN Port that the lubricant reservoir or tank outlet
Pump-to- is connected to.
Wall (Re-
mote) Mani-
fold Only
On newer units, the test port has been relocated to the
adjustment end of the pump body. The use and function
of this port is the same in either location.
