Installation
1. Install the pump on the drum cover so that the
pump’s fluid intake is 1/2 in. (13 mm) off the
bottom of the drum, as shown in Fig. 1.
2. On Models 204254 and 222087, screw the bung
adapter tightly into the drum cover’s bung hole,
adjust the position of the pump in the drum, and
tighten the bung adapter screw to hold the pump.
Always mount the pump firmly to a bracket or a
tank cover. Never operate the pump while it is not
mounted. Such use could damage the pump and
fittings.
CAUTION
System Accessories
CAUTION
Do not hang the air accessories directly on the air
inlet (E). The fittings are not strong enough to
support the accessories and may break. Provide a
bracket on which to mount the accessories.
Four accessories are required in your system: an
air shut-off valve/air bleed device, fluid drain valve,
thermal relief kit, and ground wire. These accesso-
ries help reduce the risk of serious bodily injury,
including fluid injection, splashing in the eyes or on
the skin, injury from moving parts if you are adjust-
ing or repairing the pump, and explosion from
static sparking.
DThe air bleed device relieves air trapped
between it and the air motor after the air supply
is shut off. Trapped air can cause the air motor
to cycle unexpectedly, causing serious injury if
you are adjusting or repairing the pump. Use
either a bleed-type master air valve (A) or a
quick-disconnect coupler (M) and fitting (L).
Install them near the pump air inlet within easy
reach from the pump.
DThe fluid drain valve (H) assists in relieving fluid
pressure in the displacement pump, hoses, and
dispensing valve. Triggering the valve to relieve
pressure may not be sufficient.
DThe thermal relief kit (R) assists in relieving
pressure in the pump, hose, and dispensing
valve due to heat expansion.
DThe ground wire (F) reduces the risk of static
sparking.
WARNING
NOTE: Install these accessories in the order shown
in Fig.1:
DInstall a pump runaway valve (D) to shut off the air
to the pump if the pump accelerates beyond the
pre-adjusted setting. A pump that runs too fast can
be seriously damaged.
Never allow the pump to run dry of the fluid being
pumped. A dry pump will quickly accelerate to a
high speed, possibly damaging itself, and it may
get very hot.
CAUTION
DInstall an air line lubricator (N) for automatic air
motor lubrication.
DInstall a bleed-type master air valve (A) to relieve
air trapped between it and the motor when the
valve is closed. Order Part No. 107142. As an
alternative, you can install an air line quick
disconnect coupler (M) and fitting (L) to serve as an
air-bleed device. See Detail A in Fig.1.
DInstall a Thermal Relief Kit (K) on the dispensing
valve side of the pump. To order a 900 psi
(6.2 MPa, 62 bar) Thermal Relief Kit, order Part No.
237893.
DInstall the air regulator (C) to control pump speed
and pressure.
DInstall an air line filter (B) to remove harmful dirt
and contaminants from your compressed air supply.
Install another bleed-type master air valve (A) to
isolate the accessories for servicing.
DInstall a drain valve (H) near the pump fluid outlet.
Order Part No. 210658.
DInstall a suitable fluid hose (P) and dispensing
valve (J).
