PUMPiNg HAzARDOUs LiQUiDs
When a diaphragm fails, the pumped
liquid or fumes enter the air end of the
pump. Fumes are exhausted into
the surrounding environment. When
pumping hazardous or toxic materials,
the exhaust air must be piped to an
appropriate area for safe disposal. See
illustration #1 at right.
This pump can be submerged if
the pump materials of construction
are compatible with the liquid being
pumped. The air exhaust must be
piped above the liquid level. See
illustration #2 at right. Piping used for
the air exhaust must not be smaller
than 1/2" (2.54 cm) diameter. Reducing
the pipe size will restrict air flow and
reduce pump performance. When the
pumped product source is at a higher
level than the pump (flooded suction
condition), pipe the exhaust higher than
the product source to prevent siphoning
spills. See illustration #3 at right.

The following steps are necessary
to convert the pump to pipe the exhaust
air away from the pump.
Use a Phillips screwdriver
to remove the four machine screws
(item 1-I).
Remove the muffler cap and muffler.
The air distribution valve body has 3/8"
NPT threads for installation of metal
muffler or piped exhaust.
iMPORTANT iNsTALLATiON NOTe:
The manufacturer recommends
installing a conductive flexible hose or
connection between the pump and any
rigid plumbing. This reduces stresses
on the molded plastic threads of the
air exhaust port. Failure to do so may
result in damage to the air distribution
valve body.
Any piping or hose connected to
the pump’s air exhaust port must be
groundable and physically supported.
Failure to support these connections
could also result in damage to the air
distribution valve body.
