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 3/8" 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 #8 Torx or flat screwdriver
to remove the four self-tapping screws
(item 1-J) (Plastic Valves). Use a Phillips
screwdriver to remove four machine
screws (item 1-I) (Aluminum Valves).
Remove the muffler cap and muffler.
The air distribution valve body has 3/8"
NPT threads for installation of alternate
mesh or sound dampening mufflers or
piped exhaust.
IMPOrtaNt INStaLLatION NOte:
The manufacturer recommends
installing a 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
physically supported. Failure to support
these connections could also result in
damage to the air distribution valve
body
.
