Pneumatic Connections
NOTE:
An approved pressure relief device set at 5.52 bar (80 psi) must be
installed in the air inlet line to this pump.
The pump requires 5.52-bar (80-psi) maximum input and 0.48 m
3
/min.
(17.16 cfm) to operate at 60 strokes per minute. The air supply line should
be 13-mm
(1
/
2
-in.) minimum ID. Use a length of hose between any hard
plumbing and the pump. The hose will serve as a vibration damper.
1. Purge the air supply line of all contaminants.
NOTE:
Make sure the shut-off valve is in the OFF position and the
regulator is backed all the way out.
2. See Figure 2-2. Connect the air supply hose to the
1
/
2
-in. NPT female
air input fitting (13) at the shutoff valve.
Fluid Connections
Stainless steel fittings are recommended for all connections. Liberally coat
all fitting threads with pipe joint adhesive. Tighten fittings securely to
eliminate the siphoning of air.
If the installation is to be hard-plumbed, 10-mm (
3
/
8
-in.) ID, or 1-mm
(0.035-in.) wall seamless stainless steel tubing is recommended. Install a
high-pressure fluid hose at least 305-mm (12-in.) long from the pump outlet
to any tubing to serve as a vibration damper.
Siphon Connections
Siphon Rod and Strainer
1. See Figure 3-2. Install the siphon strainer (5) on the siphon rod (4).
Tighten the thumb screw securely.
2. Install the
1
/
2
-in. NPT male connector (3), provided with the pump, into
the elbow of the siphon rod (4).
3. Connect the siphon hose (2) between the male connector and siphon
manifold (1).
Pressure Feed Connection
See Figure 3-2. The coating material may be supplied to the pump by
gravity pressure or by pressure feed from a pressure reservoir. Maximum
feed pressure should be no more than 1.38 bar (20 psi).
1. Install the
1
/
2
-in. NPT male connector (3), provided with the pump, to a
fitting in the pressure feed line (4).
2. Install the siphon hose (2) between the pump siphon manifold (1) and
the pressure feed line. The hose will serve as a vibration damper.
3. Install a shutoff valve (5) in the pressure feed line, ahead of the pump.
Do not use a check valve or fluid regulator in the pressure supply line.
