80 Years of Quality and Innovation

Sihi is a world leading designer and manuacturer o liquid ring

pumps and systems, with over 80 years o experience. Our steady

growth has been the rew ard or delivering proven technology, inno-

vation and reliability to satisied customers around the world. Sihis

reputation as a premier supplier o well-designed products and an

outstanding level o service has been built on our mission to provide

the very best in engineered solutions and lasting value. We are a

preerred supplier to the reinery, petrochemical, p olymer, pharma-

ceutical, oil & gas and power industries and we continue to grow due

to our commitment and dedication. Q uality, dependability, value and

service are our most important products and our customers are our

most important assets.

SIHI 2-Stage Liquid Ring Pumps

The heart o our condenser evacuation package is our rugged, low-

maintenance, two-stage liquid ring vacuum pump. It is the ideal

solution or handling liquid carryover, condensate and large volumes

o water vapor. It perorms seamlessly and automatically through

condenser hogging and holding. he positive displacement char-

acteristics o SIHI liquid ring vacuum pumps result in signiicantly

increased perormance even as air in-leakage increases, so your con-

denser will continue to operate closer to the design point. Our liquid

ring pump tracks condenser perormance as cooling water tempera-

ture varies, since it uses main condenser circulating water or cool-

ing. You can begin condenser hogging without waiting or ull steam

pressure, which is ideal or plants that need to come online quickly.

wo-stage liquid ring pumps are naturally suited or main condenser

evacuation service and provide long lie and optimum perormance

or your steam turbine condenser system.

Power Market Experience

As a global leader in the electric utili ty industry, SIHI has hun-

dreds o installations in conventional, geothermal and nuclear

eam power plants worldwideso we understand your needs. Maineam condenser air removal is critical to eicient plant operation,

nd an application in which we excel,but we also cover the entire

amut o power plant applications, including water-box and pump

riming, condenser hogging, deaeration, ue gas desulurization

nd y-ash conveying. We also have a signicant installation list o

umps and systems in nuclear plants around the world. All systems

upplied to North American customers are designed and built in the

SA to meet your most exacting design specications.

SIHI 2-Stage Liquid Ring Vacuum PumpHeavy duty, 2stage liquid ring vacuum pumps are the key component of ourCondenser Evacuation Systems. Tese slow running, low noise pumps haveno metal-to-metal contact, need no internal lubrication and are low main-tenance. Tey operate automatically for both hogging to holding. Pumps are

iron or stainless steel construction with no copper alloys, and come standardwith packing or optional mechanical seals.

SIHI Dedicated Hogging PackagesSIHI hogging systems utilize our rugged single stage vacuum pumps andmeet all HEI standards for main condenser shell side evacuation. Teyre

the ideal solution for peaking plants or whenever you need to get online fast.Like our Condenser Evacuation Systems, they come piped, wired and readyto go, and since they dont need steam, you can begin hogging before y ourboilers are up to full steam pressure.

Selecting an Optimal System

electing the best vacuum system or your condenser involves a thorough

understanding o anticipated plant loading, seasonal actors, condenser

perormance and design point, the efect o condenser pressure on turbine

eciency and other actors. Our engineers can assist you in estimating your

needs until you are ready or in-depth analysis.

SIHI uses sophisticated sizing and selection programs to model perormance

using your precise operating conditions. Our systems can be specied
