The model XSD1 has a 25 mm (1") inlet/discharge. The model
XSD2 has a 51 mm (2") inlet/discharge and the XSD3 has a
76 mm (3") inlet/discharge. The Equalizer
®
can be installed
in either horizontal or vertical orientations. A variety of
materials are available to satisfy temperature, chemical
compatibility, abrasion and flex concerns.
The Equalizer
®
installed on the discharge side of the pump
minimizes pulsation and protects in-line equipment. It can
also be connected on the suction side to prevent water
hammer associated with a positive inlet condition.
Install the Equalizer
®
as shown below. The use of flexible
connections and a Filter, Regulator, Lubricator (FRL) will
extend parts life. Shut-off valves on the suction side of
pump and the discharge side of Equalizer
®
will enable
maintenance personnel to safely service the equipment.
To maximize effectiveness, install the Equalizer
®
as close
as possible to the discharge of the pump.
It is important to support the pipe immediately
downstream from the Equalizer
®
. Use a tee connector
on the pump air supply line and connect the line to the
Equalizer
®
regulator body. This tee connector should be
installed after the FRL. The Equalizer
®
consumes very
little air, therefore, a 1/4” hose is more than adequate to
supply enough air volume. When the air supply to the
pump is shut down, the air to the Equalizer
®
will be shut
off as well.
NOTE: In the event of a power failure, the shut-off
valve should be closed if the restarting of the pump is
not desirable once power is regained.
AIR-OPERATED PUMPS: To stop the pump from
operating in an emergency situation, simply close
the shut-off valve (user supplied) installed in the air
supply line. A properly functioning valve will stop the
air supply to the pump, therefore stopping output. This
shut-off valve should be located far enough away from
the pumping equipment such that it can be reached
safely in an emergency situation.
