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.
CONVERTING THE PUMP FOR PIPING THE EXHAUST
AIR
The following steps are necessary to convert the pump to pipe the
exhaust air away from the pump.
U s e a P h i l l i p s s c r e w d r i v e r
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.
