Wilfley Model S3 Chemical Slurry Pumps
Wilfley hydraulic seal in actual operation.
The combined corrosive and abrasive
action of many of todays modernprocesses have required compromisesfrom traditional pumps. Slurry pumpshave generally been too heavy indesign and uncompromising for alloyconstruction. Acid pump designs havebeen too light for some of the robustapplications. A clear need for an alter-nate choice was the reason for the birthof the Wilfley S3.
T his unique Wilfley S3 was designedspecifically for corrosive/slurry applica-tions. The pumps have a strong, solidpower frame that can withstand highheads, speeds and specific gravities.It can be upgraded for extreme duties.
The pump s hydraulic parts are designed
to be made of a wide range of materials.The pump designs are flexible enoughto customize pumps for specific services.
C learly, the most outstanding featureof the S3 is the Expeller/DryLockt seal
combination. T he Expeller has been ahallmark of Wilfley pumps since 1919.Wilfley invented it and has perfected itsoperation during the last 80 years.
The Expeller seals the pump while running.The DryLockt is an adaptation of theseal that has made Wilfleys A7 ANSIchemical pump a leader in corrosive
fluid handling. T he repeatable andpredictable smooth action of the sealensures leak free startups and stops.

The DryLockt has been modified tothrive in the most aggressive slurries.There is no rubbing contact while thepump is running and no need for
cooling flushes. However, multipleflush ports are available to clear anycaking materials.
Wilfley free engineering service matchesthe pump to your specific application.Systems will be analyzed to ensureleak free, efficient and reliable pumpoperation. Each pump is tested before
leaving our plant. It is through thisthorough preparation that we canguarantee the operation of Wilfleypumps to your complete satisfaction.
Wilfleys application and engineeringstaff continue to provide the most upto date information and innovative tech-nology on pumps and pump processesto customers and the world. T he S3

Wilfley Model S3 Features and Benefits
Extra w all thickness extends w ea r
life (1/4 c orrosion a llow anc e vs .
1/8 w ith sta nd a rd ANSI/AS ME).
The large c losed impellervane s
provide highly e fficient p umping
and long we ar life. The front pump
out vanes reduce circulation.
The Dryloc k sea l is a mod ular
ca rtridg e des ign, simplifying ma in-
tenance. Slurry performance has
been improved by adding Wilfleys
new, pa tented B arrier Ring.
Optional expe ller drain and
ca sing drain (not show n)
ava ilab le for both o perational
and s afety purpose.
The Wilfley e xpe ller is a no n-co nta c ting
hydrodyna mic s ea l that provides long,
trouble free life minimizing operating c os ts
and d owntime.

Expeller performance has
been enhanced by a dding
fixed rad ial vanes on the

Wilfley Model S3 Features and Benefits
DryLock
The DryLock uses the action ofcentrifugal force combined with thesmooth actuation of bearing balls toopen and close the seal. As the pumpstarts up, the expeller evacuates theliquid in the seal area. T he balls of theDryLock are forced outward andslide up a ramp in the ball housing.
The ramp forces the balls against theactuator plate and opens the sealfaces. Upon shut-down, the balls losetheir centrifugal force allowing thespring-loaded actuator plate to moveback into its closed position. The sealis then closed.

A .R . Wilfley & Sons manufactures S3centrifugal pumps in a variety of mate-
rials including special combinationsof alloys.
Wilfley' s engineering staff has theexpertise and experience to assist inmaterial selections. To help in thisservice, Wilfley maintains an extensivelibrary of pump services and corro-sion/abrasive data. Wilfley is continuallytesting the effects of both abrasionand corrosion on a wide variety ofmaterials as well as actively developingnew ones.
Wilfleys in-house metallurgicaldepartment has developed uniquematerials to survive in the most hostileenvironments. These proprietary mate-rials were developed to extend the wearlife of parts in extreme corrosive andabrasive conditions.
C D4M C u and M axalloy 5 arecommonly used alloys. Wilfleysfoundry and metallurgical staff havedeveloped proprietary processesenhancing these alloys for improvedpump performance.

General Installation Recommendations
Choosing Pump Location
Locate the pump as close to the liquidsource as practical so the suction pipe
is short and direct with a minimum ofelbows, fittings and valves.
Place the pump in a location so the unit isaccessible for inspection during operationas well as for maintenance operationsinvolving removal and disassembly.
Foundation
The foundation should be strong enoughto absorb any vibration and to form apermanent support for the baseplate.T his is important in maintaining thealignment of the direct connected unit.
Foundation bolts of the proper sizeshould be embedded in the concretelocated by the outline drawing.
Alignment
T he pump and motor are aligned atthe factory before shipment. H owever,realignment is necessary after thecomplete unit has been installed.
G uidelines for checking and aligningthe pump components may be foundin the Hydraulic Institute Standards.
Piping
Both suction and discharge pipesshould be supported independently
near the pump so when the flangebolts are tightened no strain will betransmitted to the casing.
A check valve should be be installedin the discharge line to prevent fluidfrom flowing back through the pumpwhile it is shut down. G ate valvesshould be installed in both dischargeand suction lines to isolate the pumpduring maintenance.
Care must be taken in sizing and locatingsuction piping to prevent cavitation.
Ordering InformationWilfley pumps are engineered to operatein compliance with your specifications.C areful evaluation of pumping conditionsis needed to provide accurate pumprecommendations and quotations.
