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" (2.54 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.

Use a #8 Torx or flat screwdriver to

remove the six self-tapping screws (item

1-L).

Remove the muffler cap and muffler

(items 1-E and 1-G). The ½" NPT molded

threads in the air distribution valve body

(item 1-B).

Piping or hose may now be installed.

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.
