When it comes to making vessels, wecan manage just about anything. Butthat's not the only reason why vesselsfrom WALTHER PILOT are a good dealall round. They are also a worthwhileinvestment. You are guaranteed a pro-duct that is made in our own factoryand one that meets the high quality andsafety requirements that you take forgranted in your own production.

WALTHER PILOT recognised the poten-tial for vessel manufacture at an earlystage and has gained an excellent repu-tation as a supplier to industry and tra-des. Vessels are needed everywhere –liquids or paste-like media have to betransported in almost every sector ofindustry.

In consultation with our business part-ners, we constantly develop innovativeand tailor-made solutions. You too canprofit from this know-how. Flexible pro-duction methods allow manufacturingtime to be kept short even for specialcustomer requirements. The high qualityand safety standards are guaranteed bya qualified workforce and by continuousinvestment in new machinery.

Our market leadership in the field ofpressure pots has been constantly exten-ded by a wide range of standard andcustom-made solutions. And the trend isstill upwards.

The future is looking bright too as far asother countries are concerned. We canproduce our vessels to meet mostEuropean manufacturing standards aswell as the American ASME Code. Eventhe requirements of the Chinese SafetyLicense are fulfilled.

Many customers find pressure and vacu-um vessels so attractive because they areable to carry out several tasks at thesame time:

1. The material is safely stored – and novapours are allowed to escape.

2. The material can be stirred or tempe-rature controlled.

3. The material is delivered continuouslyand without pulsation – the ideal pre-condition for dosing purposes.

Other material delivery systems are notable to perform such "multitasking".Therefore, pressure and vacuum vesselsprovide an ideal combination of econo-mic and safety aspects. What is more,WALTHER PILOT manufactures vesselswhich make full use of all possibilities forprocess automation, even going as far asautomatic filling.

Bulk containers and autoclaves as well aspressure vessels for leak testing com-plete the product range.

But we shouldn't forget that, when itcomes to transporting material, a vesselis just a means to an end. Extensive con-tainer solutions are the result of anactive examination of everyday industri-al practice. And that is the reason whyWALTHER PILOT does not confine itsexpertise only to making vessels but isalso involved in the project managementof efficient and high quality total systemsolutions, for example for material circu-lation. All the necessary components,such as pumps, lids with lifters for origi-nal containers, filters for compressed airand material, level control and measure-ment technology, forward and returnflow controllers and ring circuits, are partof our wide range of products and servi-ces.

So why not take advantage of the com-petence of an all-rounder in all aspectsof material delivery.

WALTHER PILOT vessel solutions are aninvestment with hardly any follow-upcosts – we certainly don't earn muchfrom selling replacement parts. Whetheryou use pressure pots, vacuum vessels orpressureless containers, there are onlyvery few wearing parts. This guaranteesa maximum of process reliability with aminimum of maintenance.

Filter systems� With filtered compressed air control systems fromWALTHER PILOT you will avoid contaminating yourvaluable materials. The units are available as modules sothat, as can be seen in the above illustration of a spray-ing system for two-colour operation, other system requi-rements can also be taken into account.

� The air inlet fitting on the pressure tank itself is rever-se controllable, which means that the working pressurecan be changed at any time without bleeding the vessel.

� For pressure-sensitive applications, WALTHER PILOToffers precision reducing valves with fine adjustment.

� For media which react with humidity, silicagel filtersare available in various sizes.

� The vessels can also be equipped with material filters.We supply strainer inserts with various mesh sizes.

� We not only make vessels but provide tailor-madesolutions for all special requirements.

The filtered compressed air control-lers from WALTHER PILOT have adegree of filtration of over 97%.

Contaminants as small as 5 µm arefiltered out. This ensures an air quali-ty in accordance with ISO 8573.1

� The material can be sup-plied to the spray gun over along period without interrup-ting the job.Troublesome filling and clea-ning are no longer necessary.

� The material is safely stored.

� The even, pulsation-freedelivery ensures an excellentspray finish.

� For spray guns with pressu-re pots, the material pressureand the air pressure can beoptimally matched to eachother. This also allows for spe-cial nozzle/air cap systemswhich guarantee excellentcoating quality even for criti-cal materials.

� Since the material is deli-vered under pressure, materialflow and working speed aregenerally higher than forspray guns with cups.

� The ergonomic benefits ofspray guns supplied frompressure pots should not beunderestimated. Since there isno longer a heavy gravity cup,the gun can be handled muchmore comfortably.

� The weight advantages alsobecome positively apparent ifthe gun is used for a longerperiod.

In many cases, the use of pressure tankswill improve results. They also have a positive influence onwork ergonomics.

Special containers

Vacuum vesselsThe use of vacuum technology in storage containers offersmany advantages when it comes to keeping the properties ofthe material stable. For example, when stirring in a vacuumthere is no danger of introducing air into the material. Theabsorption of moisture from the ambient air is also avoided.This is important, for example, in the processing of castingresin, where moisture from the air or air inclusions can impairthe quality of the casting compound.

WALTHER PILOT vacuum vessels guarantee a constantlyhigh casting quality. The vessels are fitted with level sensors,so that they are filled automatically when the low limit is rea-ched. There is no need to interrupt the job.

The material is fed in via a suction valve. Below the opening,a baffle plate breaks the material apart, also serving to large-ly degas the material. This effect is reinforced by the use ofagitators, which also provide an optimum homogenisation ofthe material.

In order to guarantee the required flow behaviour, thermalconditioning can be achieved by a heating band laminatedonto the vessel.

In addition, the lid is fitted with an illuminated inspectionglass so that optical monitoring of the material is possible atall times.

The right lid for every barrel

As a system supplier for a whole range of container solutions, WALTHERPILOT also supplies the technology for transporting fluids from the original

container or tank storage to the container station for further processing.In circulation loop systems, material transport back to the tank is also

no problem.

The lids with lifting mechanisms are fitted with the necessaryequipment to suit your needs: pumps, agitators, forward and

return fittings, material filters, etc.

No aspect of material transport is left unnoticed. For exam-ple, castors and lifting systems are available for positio-

ning the original barrels, so that the barrel can be chan-ged easily and safely.

WALTHER PILOT know-how guarantees compre-hensive and permanent system solutions.

in this picture is unavoidable. The valua-ble chemicals stored in the barrels must atall costs be protected from light and tem-perature variations. So even our photogra-pher had to use a special filter.

The ghostly atmosphere...

The material is transported to the glassfibre processing station for coloration in13 different colours. With the specificati-on of developing a fault-free system thatrequired practically no maintenance,WALTHER PILOT was entrusted by ALCATEL Kabel, Mönchengladbach, withthe job of designing the appropriate pro-cess technology.

The delivery system works round theclock. Only the barrels need to be chan-ged from time to time.

The innovative plant technology helpsALCATEL to achieve a considerable increa-se in fibre production.

Level control and measurement

Capacitivemin./max. sensorsfor continuous measurementand vibrating fork sensors for limitdetection are available in various versions.

The signals are processed by analogue ordigital transducers for each application.

We can also install other technicalsolutions, e.g. ultrasound systems, to suit yourneeds.

Conventional systems (optical indicators) arealso available.

Many containersolutions require processcontrol that is matched tothe application. Automationis especially recommendedwhen, for safety reasons,contact between humanbeings and the material isto be kept to a minimum.Indicator gaugesfor level,pressureand temperatureoffer excellentpossibilities for this.

For example,the process control issupported by modernlevel measurementsystems to ensurethat containers inmaterial circulationloops can be filled without risk to wor-kers or the environment.

A sensor (1) automatically activates thebarrel pump when the minimum level isreached. At maximum level, the pump is

switched off. For safety reasons, there is asecond sensor (2) as an overfill protection.The operator is required only to change thebarrel. This is indicated by a signal sent bya further sensor (3).

To guarantee a maximum of environ-mental protection and working safety, the

barrel and mixing tank are placed oncollecting basins.

The user receives all components from onemanufacturer. The high quality individualcomponents are ideally matched to forman integrated system.
