SCANPUMP SCABA agitators
System DA - Degree of Agitation
Application Know-how for Optimal Mixing
What is the aim of agitation? For Scanpump it is ”To attain
the customers’ wanted process result by the most costeffective 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.
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.
Benefits
Technical Features
Process guarantee: Desired mixing result obtained
High Flow Propellers: Better mixing, less vibrations,
minimises forces and power consumption
Cost effective: Minimum power needed
Sealing: Maintenance work without emptying the tank
Easy service: Designed for minimised downtime and
maintenance
Modular system: Same Modular System for all agitators
Support: Our specialists will ensure best mixing result

Design Criteria
Liquid / Liquid Miscible liquids
Depending on the medias involved, they can be classified into three groups: liquid/liquid, liquid/particles and
liquid/gas.
Other kinds of application are also available but not
presented here.
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 agitators. Further development of the original 3SHP1 has given
3SHP18 mainly used in low viscosity medias and 2SHPD
for high viscosity.

SCANPUMP SCABA TOP ENTERING AGITATORS.
The agitators are of a robust, modular design and can be combined with various
types of drive units, seals and impellers. Due to this flexibility, the agitators can
be adapted optimally to the needs of the process.

Pedestal modul
The shaft coupling in the pedestal module
provides the connection between the drive
and the agitator shaft. Sleeve and flange couplings 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
alternative. This enables the bearing to be changed without the need for removing the shaft.

Shaft seals for top entering agitators
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 seal
Adapted to meet the customer’s requirements 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.
Stuffing box seal
The lantern ring, usually included, serves
as a gliding bearing and increases the
useful life of the seal.
The shaft is often equipped with a
wear sleeve.

Labyrinth seal
Seal for low-pressure processes.
Particularly suitable for digesters. The
height of the water trap is determined
by the pressure inside the tank.

Scanpump Scaba impellers
Scaba uses their own patented or designed registered impellers. Combined with our extensive design knowhow, these impellers produce the best possible process results at the lowest possible energy cost. The widespanning range of impellers enable us to select the optimum element for each individual application.
SHP1
Our high-flow propeller which is
acknowledged for its energy-efficiency and effectiveness.
It is just as effective on difficult suspensions and reactions as it is on homogenizing and mixing. Intended for
viscosities up to 50 000 mPas.
SHP18
A registered-design development of
the SHP1.
Offers better effectiveness at lower
viscosities. Low weight allows for
lighter shaft design.
SHPD
Double-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.
