By working closely with customers, Viking hasdeveloped breakthrough products with widespreadapplications.

For instance, the Viking Flow Manager

controls continuous metering or batch delivery forasphalt blending and hot mix applications, withouta flow meter. By monitoring asphalt temperatureand pump inlet and discharge pressures, it compen-sates for changes in viscosity and slip to providethe exact rate or volume needed, regardless ofchanging operating conditions.

Customer input led to another Viking advance.The traditional braided packing seal used in mostasphalt pumps necessarily leaks to keep movingparts lubricated. Customers interested in reducingthe costs of lost product, downtime and disposal,as well as fugitive emissions, helped Viking developretrofittable, cartridge-style lip and mechanicalseals that make leaking seals a thing of the past.

Our customer relationships are true partnerships.By listening and learning while out in the field, wehave accomplished more together than we couldon our own.

Service to the Asphalt Industry Problem-Solving InnovationViking Pump has supplied steam-jacketed

pumps to the asphalt industry since 1933. As theindustry has evolved, so have our products.

Working with asphalt professionals worldwide,Viking has analyzed how different asphalts fromstraight-runs to cutbacks, emulsions, blown, filled,and polymer-modified affect pump performance.Looking even further, weve minimized pumpsimpact on asphalt characteristics and performance.By responding with new designs, sizes, materials,options and operating parameters, weve worked tosatisfy each unique asphalt application.

Vikings commitment to customer needs isreflected in our international network of knowl-edgeable, factory-trained, stocking distributors andPositive Pumpcare Certified Service Centers.They provide expertise in selection, installation,commissioning, operation and service. And theyrebacked by the extensive technical expertise ofVikings field sales team and Customer SupportCenters.

Lip SealLow cost seal for all cleanasphalts, requires steam or hot oil quench.

Single Mechanical SealWith hard faces for clean andfilled asphalts, requires steamquench.

Double Mechanical SealWith hard faces for clean andfilled asphalts, requires pressurized barrier fluid.

Mechanical seals have performedwell for over a decade at a New Mexicobulk asphalt storage facility. They havepaid for themselves over and over,according to Mitch Taylor of T.P. Pump,the Viking distributor who installedthe heavy-duty pumps at the plant.

This customer was concerned aboutcleanliness and waste. They did notwant any material loss, he explained.

To meet the challenge, Viking developed a system for directing low pressure steam to the seals. Byflushing out asphalt residue there, the mechanical seals dont crack or break.

After more than a decade, wevehad to replace just two of the tenmechanical seals originally installed,said Taylor.

Refineries Terminals Hot Mix Plants Roofing PlantsThis is where asphalt production begins,

and if it doesnt move smoothly here, there maybe problems down the road or on the roof.Viking Pump delivers on the challenges facingtodays refiners.

Our cast steel asphalt pumps withstandextreme temperature changes without damage.Able to manage viscosities up to 2,000,000 SSU,a heavy-duty Viking pump can handle asphalt orany other hydrocarbon, providing year-roundversatility for seasonal asphalt producers.

With flow capabilities up to 1500 gpm (345 m3/hr), Viking pumps swiftly conveyasphalt through processing operations to storageto transport, helping to ensure that delivery is on-time and productivity on-target. Along theway, our pumps handle long pipeline head losses, thanks to discharge head capabilities up to 462 feet (200 psi/14 bar).

Speed is critical in terminal operations. Soloading, unloading, and blending equipment allneeds to function quickly and reliably.

Bi-directional pumps are one way Viking has helped streamline terminal flows. Instead ofrequiring two sets of pumps, drives and piping, a single pump can change direction to load orunload with equal efficiency. We also speed upasphalt transfer with a powerful suction lift thatallows pumps to draw down rapidly from the top ports of barges, railcars or tankers duringunloading.

Vikings Flow Manager can help reduce the need for multiple tanks with premixedasphalt grades and cutbacks, too. With this tool,terminals can use fewer base materials and mixon-demand, cutting investment expense andenergy use.

For many hot mix manufacturers, the pavingseason is short. When demand is high, they need tooperate 24/7. Downtime must be kept to a minimum.

What hot mixers need is simple, dependablepump operation year in and year out. Evenafter sitting dormant all winter. Our internal geardesign uses just two moving parts for reliableoperation and easy maintenance.

And when paving season is on and demand is high, hot mixers can rely upon Viking's vaststocking distributor network to provide fast andknowledgeable service whether its repairs,replacement parts or complete pumps.

Asphalt used for roofing products is anotherbreed. With crushed limestone and other abrasiveagents, filled asphalt takes on the texture of liquidsandpaper. Thats why hardened, heavy-dutyViking Pumps are such a sound investment.Specially designed for roofing applications, theyfeature cast steel housings and tungsten carbidebushings and seals. With pumps durable enoughto last years instead of months, Viking can helpcut life-cycle costs dramatically.

Asphalt fumes can be unpleasant for indoorplant workers as well. With the option of singleor double mechanical seals, Viking can virtuallyeliminate fugitive emissions from asphalt pumps.

Vikings are the preferred pumps inother asphalt applications as well,including:

Distributor trucks, for spray injection to fill and coat roadbed aggregate.

Pipe lining, where liquid asphalt is used to line sewer pipe in-plantand in-place.

Tar kettles, or portable heat-and-spray units, for on-site roofing build-up, foundation-sealing and crack-filling.

Asphaltic insulation in automotiveand appliance manufacturing lines for sound deadening.

Aluminum refining, for pumping pitch
