Agitator (Model No: SVE01):-
Our SVE01 agitators are designed for a wide range
of service in the chemical, pharmaceutical, ethanol
and biofuels, water and wastewater, Flue Gas
Desulfurization, power and other general process
industries. The agitators feature a new, high-
efficiency gearbox designed specifically for agitator
service. Models are available in right angle and
parallel shaft configurations to meet specific
application requirements from critical chemical
reactor systems to routine storage.
Advantages:-
• Quick and easy seal change capability that
saves time and reduces maintenance costs
• Variety of seal options for application
versatility
• High energy efficiency due to an optimized
gear design and lighter weight shaft
diameter requirements
• Reversible rotation to meet a variety of
process requirements
• Reliable performance and long life resulting
from the gearbox with heavy duty output
shaft and bearings.
Side Entering Agitators: -
Our Side-Entering Agitators offer the same
ruggedness, dependability and simplicity of design
found in our other high-quality turbine agitators
and mixers. Our Side-Entering Agitator is a right-
angle drive exclusively engineered for side-entering
agitator service.
Our Side-Entering Turbine Agitators work efficiently
when a tank is too large for convenient installation
of a top-entering agitator, or where headroom is
severely limited. For large tank installations, several
smaller side-entering agitators may be more
efficient and economical than a single, larger unit.
The wide range of power selections and seal
options combined with two standard output speeds
and accurately sized impellers. Our Side-Entering
Agitators for process applications involving
continuous blending, heat transfer, mass transfer
or solids suspension.

Agitator (Model No: SVE03):-
Today's applications demand high-performance
process equipment accompanied by total support
for customers' mixing needs. To address these
requirements, we offer a line of top-entering and
portable mixers. Direct-drive and gear-reduced
designs for both open and closed tank applications
are available. Superior materials of construction
throughout, along with advanced modular designs
give each one the strength, flexibility and reliability
to perform to the same standards as all our agitators
and mixers.
Design Features
• Drive - Direct-drive or gear-reduced designs
are available giving the end user the
necessary mixer speed choices to adapt to
changing process conditions. Right angle
worm drive models are available where low-
headroom clearance is required.
• Mounting options (open tank) - Angle risers
or flat plate mounts are available for proper
mixer positioning above open tanks.
• Sealing options (closed tanks) - SVE offer the
broadest range of commercially available
mixer sealing options on the market. They
include the following: a standard 4-ring
stuffing box, v-ring or lip seal, single
mechanical seal, single mechanical cartridge
seal and double mechanical cartridge seal.
• Shaft lengths –SVE provides numerous shaft
length options. When conditions change,
they can be easily changed by means of the
convenient chuck or flanged shaft coupling.
• Impellers – SVE’s mixing expertise includes
low shear liquid-liquid/solids blending, gas
dispersion, high shear blending and viscous
mixing. Whether it is R&D or production
phase, we have the expertise to solve your
mixing challenges.

Scrapper Mechanism:-
These systems are used to clean waste water
through the process of settling of heavy particles
of sludge and suspended matter in water. The
product offered by us uses a scraper Mechanism
that rotates at the bottom of the conical bottom
tank to scraps the sludge settled on the slope of
the conical bottom and the blades bring down the
sludge to the center of the cleaning tank, from
where it is pumped out. We also offer these
systems in custom-built range and at reasonable
market prices.
Focculators: -
Flocculators are custom designed for all your
flocculation needs. Energy is transferred into
water through the use of paddle wheels which
promote particle agglomeration to form large,
fast-settling floc particles. Typically the process
applies tapered flocculation to the inlet stream,
where the first stage has high energy input
(velocity gradient), and subsequent stages have a
reduced velocity gradient.
Flocculator mechanisms can be oriented
horizontally or vertically depending upon drive
location and/or customer
preferences. Horizontal flocculator drives can
have a dry well (requiring a wall penetration) or
a wet well arrangement.

Straight Blade Turbine:-
• Close clearance design for operation near the tank bottom.
• Excellent for low-liquid-level solids suspension & laminar
flow applications
• Designed for use in laminar regime (Reynolds number < 50)
applications.
High Efficiency Impeller: --
• An established industry standard for axial flow impellers.
• Ideal for blending, heat transfer and solids suspension.
• Good impeller for applications where the viscosity changes
over a wide range causing the flow regime to vary between
turbulent and laminar flow.
• Extremely efficient creates greater fluid motion with less
energy
Axial Flow Impeller:-
• Excellent performer in abrasive solids suspension, liquid-
solid-gas and boiling applications.
• High-solidity blade design translates into higher gas rates
and viscosity values over other high efficiency designs.
High shear Impeller:-
• Customize levels of shear to suit your process.
• Proper fluid turnover minimizes the need for auxiliary
pumping impellers.
• Small particles possible, 2 microns achieved in processes
such as micro-encapsulation.
• Traditional dispersion blades can also be used in high shear
applications.
Advance Impeller Designs

Concave Blade Impeller:-

factor effect)

gas.

Pitched Blade Turbine:-
• Axial flow design suitable for wide changes in process
viscosity.
