THE EQUALIZER®

All reciprocating pumps experience a pres sure fluctuation. The Equalizer® minimizes unwanted pressure fluctuation by provid ing a supplementary pumping action. This is accomplished by using a diaphragm as a separation membrane within the Equalize~ 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 Equalize~ 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.

PHASE1 PHASE 2

LIQUID SIDE LIQUID SIDE

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

The Equalize~ automatically sets and main tains the correct air pressure matching the variations in liquid flow or discharge pressure generated by the pump. A shaft attached to the Equalize~ diaphragm triggers the addition or deletion of the air within the non-wetted side of the Equalize~. The Equalize~ 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 procezss system from unwanted pulsation or pressure fluctuation.

Contact your local Wilden distributor for fur ther information on the Equalizer® and other pumping solutions.

phase 2). When the pump redirects its motion upon stroke completion, the liquid discharge pressure decreases forcing 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.

CAUTION: DO NOT EXCEED 125 PSIG AIR PRESSURE.

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

Prevention of static sparking - If static spark ing occurs, fire or explosion could result. Pump, Equalizer®, valves, and containers must be grounded when handling flammable fluids and whenever dis charge of static electricity is a hazard.

INSTALLATION

The model SO/';; has a /';;" inlet/discharge. The model S01 has a 1" inlet/discharge. The model S02 has a 2" inlet/discharge. The Equalizer® can be installed in either direction. A variety of materials are available to satisfy tempera ture, chemical compatibility, abrasion and flex concerns. The Equalize~ installed on the dis charge 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 SO~ is engineered for use with Wilden ~ (6mm) and Y2 (13mm) pumps. The model S01 is engineered for use with Wilden 1" (25mm) pumps. It can also be used with the 1 /';; (38mm) in applications where the discharge pressure is less than 50 psi. The model S02 is engineered for use with Wilden 1 /';; (38mm) and 2" (51 mm) pumps.

INSTALLATION

TROUBLESHOOTING

When there is a significant drop in the fluid discharge pressure, there will be a notice able release of air through the small bleed hole in the air regulator body. This is how the Equalize~ automatically adjusts itself for optimal suppression. This is a good way of verifying proper operation of the unit. If there is a continu ous discharge of air out this hole during steady fluid discharge pressure, the Equalize~ is not functioning properly and should be inspected.

The S01 and S02 air regulator body houses three 0-rings which may need to be replaced.

A few drops of oil in the top of the regulator every 200 hours of operation will significantly extend the life of th"ese 0-rings. The SO/';; uti liz-

WIL-19010-E-04 5

Install the Equalize~ as shown below. The use of flexible connections and a Filter, Regulator, Lubricator (FRL) will extend parts life on the SD1 and S02. Lubrication is not needed for the soy,;. Shut off valves on the suction side of pump and the discharge side of Equalize~ will enable maintenance personnel to safely service the equipment. To maximize effectiveness install the Equalize~ as close as possible to the dis charge of the pump. It is important to support the pipe immediately downstream from the Equalizer®.

Use a tee connector on the pump air sup ply line and connect the line to the Equalizer® regulator body. This tee connector should be installed after the FRL. The Equalizer® con sumes very little air, therefore, a 1/4" hose is more than adequate to supply enough air vol ume. When the air supply to the pump is shut down, the air to the Equalizer® will be shut off as well.

es 3 slipper seals with back-up 0-rings which allow lubrication-free operation.

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.

Air leakage at the bottom of the 801 and S02 air regulator body normally requires the tightening of the three screws located in the air chamber. If leak age continues, the gasket between the air regula tor body and air chamber should be replaced.

If air bubbles in fluid discharge line are present, check for diaphragm rupture and tightness of clamp bands. · ·
