Air Exhaust Ventilation
NOTE:
The pump exhaust air may contain
contaminants. Ventilate to a remote area if the exhaust
could contaminate your fluid supply.
NOTE:
The air exhaust port is 3/4 npt(f). Do not restrict
the air exhaust port. Excessive exhaust restriction can
reduce pump performance.
To provide a remote exhaust:
1. Remove the muffler (M) from the pump air exhaust
2. Install a conductive, grounded air exhaust line (N)
and connect the muffler (M) to the other end of the
line. The minimum size for the air exhaust line is
19
mm (3/4 in.) ID. If a line longer than 4.57 m (15 ft)
is required, use a larger diameter line. Avoid sharp
bends or kinks in the line.
3. Place a conductive, grounded container (P) at the
end of the air exhaust line to catch fluid in case of a

. 3: Venting Exhaust Air
Be sure the system is properly ventilated for your type
of installation. You must vent the pump air exhaust to
a safe place, away from people, animals, food
handling areas, and all sources of ignition when
pumping flammable or hazardous fluids. Diaphragm
rupture can cause the fluid being pumped to exhaust
with the air. Place a grounded container at the end of
the air exhaust line to catch the fluid. See F
