OPTIMAL MIXING WITHIN THE PROCESS INDUSTRY.

Our long experience, our knowledge of the processes and the ability to use this knowledge in our own design programme have given even more effective agitators for all kinds of mixing.

The demand to acheive a perfect result is to get an optimal liquid motion for the specific process. Through research and theoretical calculations we have developed a correlation between the liquid’s surface velocity and what we call Degree of Agitation - DA. This and the choice of impeller is the foundation to decide the demand of the mixing for different processes.

SCANPUMP SCABA agitators

What is the aim of agitation? For Scanpump it is ”To attain the customers’ wanted process result by the most cost-effective solution”.

Choosing and designing agitators is related to the process in which they will operate. Many factors affect the process and mechanical aspects of the design procedure. Important considerations are type of process, type of liquid, volume, the shape of the tank etc. In some applications the density, viscosity and solid content are the dominant factors.

Design CriteriaDepending on the medias involved, they can be classi-fied into three groups: liquid/liquid, liquid/particles and liquid/gas.

Other kinds of application are also available but not presented here.

- Keeping liquid homogeneous- BlendingViscosity 1-10 000 mPas.Chemicals, Juice, Milk, Sugar, Oils, Soap, Plastics,Paint, Latex, Lime, Sugar solu-tions, pH-adjustment, Wastewater...

Liquid / Liquid Miscible liquids

- Keeping liquid homogeneousViscosity 10 000 - 1 milj. mPas orup to paste consistency.Oils, Latex, Lime slurry, Cream, Paint, Glue, Grease, Youghurt...

- Keeping liquid homogeneous / BlendingViscosity 1-5000 mPas.

High Flow Propeller3SHP1


For the liquid/liquid processes the design criteria is a certain amount of Liquid Motion. The suitable impeller is the patented SCABA High flow Propeller type 3SHP. It revolutionised the market by its ability to lower the power need drastically. It suits both to side and top entry agita-tors. Further development of the original 3SHP1 has given 3SHP18 mainly used in low viscosity medias and 2SHPD for high viscosity.

Design criteria in these processes are Shear forces and Liquid Motion. The patented special turbine SRGT with its unique properties is the optimal impeller.

This turbine disperses more gas before flooding which generates higher masstrans-fer. Furthermore, no power drop occurs when gased.

SCANPUMP SCABA AGITATORS

Our calculation programs allow for unlimited variation of tank sizes, media data, agitator impellers, speeds and shaft combinations.

Modern computerized machine tools are used in the production of our agitators.

Drive unitThe drive unit selected is determined by the pro-cess requirements and the customer’s wishes. The agitator can be equipped with gears, paral-lel shaft gears, bevel gears or V-belt drives.

Pedestal modulThe shaft coupling in the pedestal moduleprovides the connection between the driveand the agitator shaft. Sleeve and fl ange coup-lings are standard. Radially split couplings are used for special applications. The pedestal module is equipped with a double spherical roller bearing with adapter sleeve. For a V-belt drive and certain special applications, an extra shaft bearing is built into the pedestal module. The SCABA shaft bearing can be used as an The SCABA shaft bearing can be used as an The SCABAalternative. This enables the bearing to be chan-ged without the need for removing the shaft.

Housing for shaft sealThis is equipped with a suitable seal. The con-necting fl ange of the housing can be supplied in different sizes.

Shaft couplingThe agitator shaft is equipped with one or more shaft couplings, if necessary. The couplings are of fl ange type, although if the hygienic require-ments are strict, threaded shaft couplings can be supplied instead.

The shaft seals are designed to maintain the required pressure in the tank or to prevent leakage through the shaft entry. Seals are also used to prevent impurities from entering the tank, or to prevent damage to the agitator by splashing or by vapour from the process liquid.

Mechanical sealAdapted to meet the customer’s re-quirements on performance and the preferred seal supplier. The seal housing can be designed to allow the seal to be changed without removing the agitator from the tank.

Stuffi ng box sealThe lantern ring, usually included, servesas a gliding bearing and increases the useful life of the seal. The shaft is often equipped with a wear sleeve.

TH sealHygienic seal designed to prevent the ingress of oil and impurities into the pro-cess liquid. Has a labyrinth function.

TS sealLip seal designed to prevent the ingress of impurities into the process liquid. Protects the agitator from splashing and from attack by the vapour in the tank.

Labyrinth sealSeal for low-pressure processes.Particularly suitable for digesters. Theheight of the water trap is determinedby the pressure inside the tank.

Scanpump Scaba impellersScaba uses their own patented or designed registered impellers. Combined with our extensive design know-how, these impellers produce the best possible process results at the lowest possible energy cost. The wide-spanning range of impellers enable us to select the optimum element for each individual application.

SHP1Our high-fl ow propeller which is acknowledged for its energy-effi cien-cy and effectiveness. It is just as effective on diffi cult sus-pensions and reactions as it is on ho-mogenizing and mixing. Intended for viscosities up to 50 000 mPas.

SHP18A registered-design development of the SHP1. Offers better effectiveness at lower viscosities. Low weight allows for lighter shaft design.

SHPDDouble-acting propeller for high viscosities, up to paste consistency.Also suitable for very gentle stirring. Due to the double-acting function, the liquid is pumped both downwards and upwards.

SRGTPatented turbine intended for gas dispersion. Due to its design, the power demand is constant at varying gas fl ows. Performs very well also on three-phase systems comprising liquid - gas - particles.

Other agitator elementsOur range also includes impellers of conventional type.

Applications• Mixing• Homogenizing• Suspensions• Reactions• Medium-high viscosities
