Mounting Accessories
Mount the pump (E) to suit the type of installation
planned. F
. 2 illustrates a wall mount system. Pump
dimensions are shown on page 36.
1.
Be sure the mounting surface can support the
weight of the pump, bracket, hoses and accesso-
ries, as well as the stress caused during operation.
2.
Position the wall bracket about 1.2-1.5 m (4-5 ft)
above the floor. For ease of operation and service,
make sure the pump air inlet, fluid inlet, and fluid
outlet are easily accessible.
3.
Drill mounting holes in the wall. Attach the bracket to
the wall. Use screws that are long enough to keep
the pump from vibrating during operation. Be sure
the bracket is level.
Install the Muffler
The muffler (C) is shipped loose. Screw the muffler into
the muffler port before installing the pump.
Air Inlet Fitting
A 1/4 npt air inlet fitting 245718 (113) is supplied on bare
pumps 234084 and 234085. It is held in place with a set-
screw (47). Loosen the setscrew before removing the fit-
ting. Tighten the setscrew to hold the fitting in place.
A 3/8 bspp(m) air inlet fitting (245682) is supplied on
Models 245934 and 245935.
Air and Fluid Hoses
Be sure all air hoses (A, P) and fluid hoses (R, U) are
properly sized and pressure-rated for your system. Use
only electrically conductive fluid hoses. Fluid hoses
should have spring guards on both ends. Use a swivel
(S) between the fluid hose (R or U) and the gun (T) to
allow easier gun movement.
Air Line Accessories
Install the following accessories in the order shown in
F
. 2, using adapters as necessary:
•
A bleed-type master air valve (B) is required in your
system to relieve air trapped between it and the air
motor when the valve is closed. Be sure the bleed
valve is easily accessible from the pump.
•
A pump air regulator (D) controls pump speed and
outlet pressure by adjusting the air pressure to the
pump. Locate the regulator close to the pump.
•
A gun air regulator (N) controls air pressure to the
air-assisted spray gun.
•
An air line filter (M) removes harmful dirt and mois-
ture from the compressed air supply.
•
A second bleed-type air valve (L) isolates the air line
accessories for servicing. Locate upstream from all
other air line accessories.
Fluid Inlet Adapter
A 3/4 npt fluid inlet adapter (115) is supplied on Models
234084 and 234085 only. Models 245934 and 245935
have a 1” bspp female port.
Fluid Line Accessories
Install the following accessories in the positions shown
in F
. 2, using adapters as necessary:
•
A fluid filter (F) with a 60 mesh (250 micron) stain-
less steel element, to filter particles from the fluid as
it leaves the pump. Install a fluid drain valve (G),
which is required in your system to relieve fluid pres-
sure in the hose and gun.
•
A fluid shutoff valve (H) shuts off fluid flow.
•
A fluid pressure regulator (J) allows more precise
adjustment of the fluid pressure.
•
A gun or valve (T) dispenses the fluid. The gun
shown in F
. 2 is an air-assisted spray gun for light
to medium viscosity fluids.
•
A fluid line swivel (S) allows easier gun movement.
•
A suction kit (K) allows the pump to draw fluid from a
fluid container.
•
A 3/8 BSPP female port (Z) allows for fluid recircula-
tion.
CAUTION
The pump must be suction-fed in order to operate
properly. Pressure feeding the pump will cause bel-
lows seal failure.
