Motor
The motor drives the connecting rod which moves the
diaphragm.
Pressure
Switch
The pressure switch at the pump outlet turns the motor
on
and of
f to control paint
pressure.
Diaphragm
The diaphragm is the heart of the pump. Driven by the
connecting rod and motor , the movement of the dia-
phragm
draws paint
through the suction hose and to the
outlet
valve.
Priming V
alve
The priming valve assists in priming the pump during
startup. Turning the priming valve counterclockwise
causes the paint to drain directly back into the pail
through the priming tube. T urning the knob clockwise
causes
the paint
to flow through the fluid outlet valve
and
to
the hose, roller valve and extension
.
Outlet V
alve
The outlet valve has a ball check which prevents paint
from flowing backwards into the pump. This helps keep
an
even supply of paint
to the roller each time you
trigger
the roller
valve.
Inlet V
alve
As
the diaphragm draws paint from the suction tube, the
paint
passes through the inlet
valve which opens to allow
paint
into the pump.
Outlet Hose
The hose has swivel-type couplings for easy assembly.
A
larger diameter outlet hose and chemical-resistant out
