Maximum temperature limits are based upon
mechanical stress only. Certain chemicals will
significantly reduce maximum safe operating
temperatures. Consult Wilden Chemical Guide for
chemical compatibility and temperature limits. Plastic
Equalizers are manufactured with virgin plastic and
are not UV-stabilized. Direct sunlight for prolonged
periods can cause deterioration of these plastics. In
this situation a metal Equalizer®is suggested.
Wear safety glasses. When diaphragm rupture occurs,
material being pumped may be forced out air exhaust.
WARNING Prevent static sparking. If static sparking
occurs, fire or explosion could result. Pump, Equalizer®,
valves and containers must be grounded when
handling flammable fluids and whenever discharge of
static electricity is a hazard.
caution: Do not exceeD 8.6 bar (125 psig) air pressure.
A compressed air line attached to the air regulator body sets
and maintains pressure on the air side of the diaphragm. As the
reciprocating pump begins its stroke, liquid discharge pressure
increases which flexes the Equalizer®diaphragm inward. This
action accumulates fluid in the liquid chamber (see Phase 2).
When the pump redirects its motion upon stroke completion,
the liquid discharge pressure decreases and compressed air
in the air side forces the Equalizer®diaphragm to flex outward
displacing the fluid into the discharge line (see Phase 3). This
motion provides the supplementary pumping action needed to
minimize pressure fluctuation.
Section 3
How It works—DAMPENEr
The Equalizer®automatically sets and maintains the correct air
pressure matching the variations in liquid flow or discharge
pressure generated by the pump. A shaft attached to the Equalizer®
diaphragm triggers the addition or deletion of the air within the
non-wetted side of the Equalizer®. The Equalizer®automatically
adjusts to any pressure and/or flow setting of the pump with
no need for manual adjustment of the unit and/or system. The
Equalizer®has proven to be the cost effective choice for protecting
your liquid process system from unwanted pulsation or pressure
fluctuation. Contact your local Wilden distributor for further
information on the Equalizer®and other pumping solutions.
All reciprocating pumps experience a pressure fluctuation. The
Equalizer®minimizes unwanted pressure fluctuation by providing
a supplementary pumping action. This is accomplished by using
a diaphragm as a separation membrane within the Equalizer®to
trap a given volume of liquid on one side and pressurized air on the
other. When the fluid pressure falls in the system, the Equalizer®
supplies additional pressure to the discharge line between
pump strokes by displacing fluid via diaphragm movement. This
movement provides the supplementary pumping action needed
to virtually eliminate pressure variation and pulsation.

XSD1½ HS PERFORMANCE
These charts show discharge head fluctuations for
a diaphragm pump with and without a dampener.
By reviewing the variation in pressure, the level of
dampening can be estimated for an application. For
example, the head pressure generated by a 38 mm
(1-1/2")” pump operating at 6.8 bar (100 psig) air
inlet pressure and 6.2 bar (90 psig) head pressure
varies between 0.8 bar (12 psig) and 7.4 bar (108 psig)
resulting in a total pressure fluctuation of 96 psig
for each stroke. When an XSD1 1/2/SZSS/LEL/0770
dampener is installed in the application, the head
pressure varies between 5.1 bar (74 psig) and 6.8 bar
(99 psig) resulting of a pressure fluctuation of only 1.7
bar (25 psig). This results in a 74% reduction in head
pressure fluctuation.

NOTES

WIL-12230-E-04 9 WILDEN PUMP & ENGINEERING, LLC
The model XSD1-1/2 Hygienic Series™ has a 38 mm (1-1/2”)
tri clamp style inlet/discharge. The model XSD2 has a 51 mm
(2”) inlet/discharge. The model XSD3 has a 76 mm (3”) inlet/
discharge. The Equalizer®can be installed in either direction.
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. The model XSD1-1/2
Hygienic Series™ is engineered for use with Wilden 38 mm (1-
1/2”) PX4 Hygienic Series™ pumps. The model XSD2 Hygienic
Series™ is engineered for use with Wilden 51 mm (2”) PX8
Hygienic Series™ pumps. The model XSD3 is engineered for
use with Wilden PX15 Hygienic Series™ pumps.
Install the Equalizer®as shown above. The use of flexible
connections and a Filter, Regulator, Lubricator (FRL) will extend
parts life on the. 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.

1) When there is a significant drop in the fluid discharge
pressure, there will be a noticeable release of air
through the small bleed hole in the air regulator body.
This is how the Equalizer®automatically adjusts itself
for optimal suppression. This is a good way of verifying
proper operation of the unit. If there is a continuous
discharge of air out this hole during steady fluid
discharge pressure, the Equalizer®is not functioning
properly and should be inspected. The air regulator
body houses three (3) Glyd rings.
2) Fluid leakage around the clamp band area is normally
stopped by tightening the clamp band bolts. If
leakage continues, unit should be disassembled and
inspected.
3) Air leakage between the adapter plate and air chamber
requires tightening of four air chamber bolts on the
inside of the air chamber.
