The multi-S mixer series was born from Satake's cutting-edge
mixing technology and commitment to products.
The belt reducer type is a mixer that is a step ahead of
the rest, responding precisely to user needs by completely
exploring compactness, light-weight, and high efficiency.

2Extensive achievements inusage are proof of trustThe Multi S Mixers, born from Satake’s many yearsof experience and novel technology, are available ina wide range of variations from 3.7kW to 30kW (topmount type and side-mount type models), allowing
you to choose the best model that meets yourneeds. Satake's Multi S Mixers of belt reducer type
is the most trusted belt type mixer with an extensive
track record of use, born from the eyes of ourdedicated engineers.
In addition, it also features a high-efficiency andhigh-discharge eco-impeller developed by theworld's top mixing technology laboratory. We offerproducts that satisfy both hardware and software
requirements.

Side-mount type(S4)3Top-mount type (S3)Features

Model coding• A simple and compact design of the mixer structure has madehandling, maintenance, and inspection easier. The design isbased on the user's perspective and respects the user's needs.
• The novel AF100 impeller, which is exclusively designed for theside-mount type, has significantly increased the discharge flowrate.
• The shaft sealing can be selected from a wide range ofoptions depending on the condition of the liquid in the tank. Inaddition, replaceable gland packings are also available when
the tank is full of liquid.
• The belt cover is made of FRP resin (S3 and S4), making it
extremely lightweight (applicable to the Fire Service Law). The
bottom plate of the belt cover is split into two, making it easy
to install and remove.
• The vibration of the motor part is minimized by increasing therigidity of the motor base.
• The V belt for high-speed drive system is used. It has an
excellent life span, oil resistance, heat resistance, and alsoanti-static. And of course, the operation noise is also quiet.
• The shaft sealing part, which is the important part of a mixer,
uses a deep groove ball bearing shield type that is oil-less. Theseals are designed to be sufficiently long-lasting to support theoutput of each series.

Utilizing advanced technology - ImpellerSupermix HR100 Impeller (for Top-mount type)
Satake are dedicated in promoting research and development (R&D) of impeller
blades based on fluid engineering and impeller blade theory. The impellers
born from these R&D are called the Supermix® series, and their superior
performance are widely used in various applications.
The Supermix HR100 impeller is designed by considering the shape of bladesurface, angle of attack and camber ratio. This impeller is a low shear andenergy-saving axial flow type that feature high discharge performance at low
power by utilizing a multiple bending structure with twisted-down blade tip toprevent flow separation behind the impeller blade.
Thereby, it is suitable for liquid-liquid mixing, solid-liquid dispersion, anduniform suspension of emulsified microcapsules (latex, etc.), and particles thatare easily crushed and light-weight. Additionally, its characteristics can also
be demonstrated in combination with other type of impeller by utilizing its
excellent axial flow effect.

type

The AF100 impeller features an air-foil cross-sectional design as a result ofnumerous research and experiments to improve the discharge efficiency of theimpeller blades.
Moreover, the impeller blade’s plane shape was designed with a skew back tominimize the impact fluctuation associated with the characteristic cavitation
observed in side-mount type mixers.
The AF100 impeller is the result of rigorous research by our engineers, which
has reduced the impact fluctuation during rotation, thereby significantlyimproved the discharge efficiency.
This makes the AF100 impeller is an ideal impeller blade for side-mount typemixers.

•The AF100 impeller is made of cast stainless steel.
•The impeller blades with diameter up to 680 mm are cast as a one-pieceunit. Meanwhile, the impeller blades with 680 mm or more in diameter are
fabricated as an assembled unit.

Mounting position and flow pattern
One of the factors that determines mixing efficiency is the mounting position of a mixer.
To determine the mounting position of a mixer, decide the flow pattern that meetsthe mixing objective by considering the purpose, specific gravity, viscosity, and otherproperties of the liquid, as well as the mixing ratio, mixing time, etc.

h=1.0〜3.5d
Note: In the case ofsolids suspension
h=0.25〜0.5d
B=0.1D
C=0.025D•Center mounting with baffles

The swirling flow is controlled by thebaffles, and up-and-down flow becomesdominant. Since the flow becomesturbulent, the mixing effect is enhanced.
Normally, two to four baffles are installed
equally near the inner wall of the tank andperpendicular to the rotating flow is mostsuitable.

h=1.0〜3.5d
Note: In the case ofsolids suspension
h=0.25〜0.5d
d>0.35D
ε=0.5dd≦0.35D
ε=0.25D•Off-center mounting

If the mixer is mounted off-center without
baffles inside the tank, it eliminates theconcentric flow against the tank, particularly
in low viscosity liquids, thereby resulting ingood turbulent flow.

Side-mount typeh=1.0〜1.5d•Side-mounting mixer

Generally, similar as to the vertical type,
except that the side-mount type is mostly
used in deep tanks with medium viscosity
or less. For installation in a tank, it isnecessary to maintain an off-center angle
about 10° as shown in the figure above.
This eliminates the need of baffles and alsoenables to prevent swirling flow.

Regarding the operation that the liquid level passes over impeller position and empty operation•What is the operation that the liquid level passes over impeller position?

In case of increasing or decreasing the liquid while running the mixer, the bottom impeller is from the stable condition without creating
steady suction vortex (at the MIN.L.L. on the drawing) to the fully exposed in air condition (or conversely) within 10 minutes. Failure to doso may cause bending of the shaft. (Please check shaft runout, looseness of bolts, etc.)•What is empty operation?

A condition in which the bottom impeller is completely exposed in air due to operation through the liquid level. In the case of empty
operation, there is no vibration control effect from the liquid, which can lead to shaft bending. Please stop the operation within 10 minutes.
