Direct Drive Air Mixer Flange Mount

The flange mounted, air driven mixer uses 316SS
shaft and 316SS marine propellers. Single propeller
models have one left-handed propeller pumping
downward in normal operation. Dual propeller
models have one each left-hand and righthand
propellers providing counterflow mixing. Air control
valve included to allow speed adjustment. Motor
may be stalled without damage.
Model BF-7.4-27S

Mixer Selection

These mixers have been designed, engineered
and built to provide long life and trouble-free
service in a wide variety of blending/mixing
operations. These mixers are popularly used to:
final product, and other parameters. Our
portables are available at either 350 or 420
RPM (gear-driven) or 1750 RPM (direct-
drive). If you have any questions or wish
to discuss your mixing/blending application
with us, please feel free to call one of our
sales engineers.
1. Blend liquids.
2. Suspend or dissolve solids
3. Disperse immiscible liquids
4. Disperse small amounts of gases in
    liquids
Selection Chart
These portable mixers can be clamp- or base-
mounted on beams, tank walls or other
supports. Angle of entry may be adjusted to
meet specific mixing requirements. These
portable mixers find use in a variety of dif-
ferent industrial applications…waste treat-
ment, water treatment and batch chemical
preparation. These portables are also ideal
for mixing paints, varnishes, polymers, textile
sizes and dyes, pharmaceuticals, soaps and
countless other materials from 1 to over
25,000 CPS viscosity. In the following pages,
we present specifications, dimensions and
dimensional drawings and other information
to help you select the proper mixer for your
application, depending on the size of the
batch, the size of the batch, components and
The chart below is intended to provide some
basic guidelines for selecting the proper
mixer(s) to provide mild blending of various
viscosity liquids in different size tanks. This
chart is based on an approximate mix/blend
time for two liquids of 30 minutes, with both
liquids already in the tank. Mixing times will
be shortened if one liquid is added to a
second liquid while the mixer is operating.
Powders should always be added while the
mixer is running. This chart also applies to the
suspension of solids with settling velocities of
less than one foot per minute. For more rapid
or vigorous mixing, use a mixer one or two
sizes larger. Dual propellers are recommended
for tanks 1000 gallons and larger at viscosity's
of 1000 CPS and higher.

Proper Mixer Mounting and Positioning

In most applications involving small
mixing tanks of 1000 gallons or less, the
mixer is clamped to the side of the tank.
Optimum mixing will be achieved when
the mixer is angled from the tank wall,
either off center (figure 1) or on center
(figure 2). Improperly mounting a portable
mixer will greatly lessen mixing
efficiency, cause vibration and could
possibly damage the mixer.
Angling off center is preferred when
good material turnover is required, as in
mixing a slurry. Angling on center is desired
for more gentle mixing and when
vortexing must be minimized.
Larger size tanks may require that a
mixer be mounted directly in the center of
the tank with the shaft vertical (figure 3).
When a mixer is used in this arrangement,
baffles are recommended to prevent the
contents of the tank from turning in the
direction of the mix. If this occurs, mixing
action will be poor.
Such baffling will avoid vortexing and
allow mixing to be as thorough as possible.
These suggests that four baffles
be used, located 90° apart and sized
approximately 1/12 of the tank diameter.
The baffle should not fully extend to the
bottom of the tank and a gap should be
provided between the baffle and the
tank wall.
FIGURE 1 - Angling the portable mixer off center
is the position recommended for rapid turnover
of tank contents and good bottom washing.
FIGURE 2 - On center angling will produce good
mixing with minimum vortexing. Tank contents
turn over thoroughly but gently.
FIGURE 3 - For mixing in larger tanks, the mixer
is often placed vertically on center. In this con-
figuration, baffles are recommended to prevent
the contents of the tank from rotating, avoid
vortexing and achieve good mixing and top-to-
bottom turnover.
