For drawing the material
to be mixed from the
top to the bottom.
Local shearing forces.
Generates axial flow
in the vessel. Used at
medium to high speeds.

and the bottom. Minimum
shearing forces. Used at
medium to high speeds.
Ø 5, 9cm
Ø 1.5, 2.5, 4cm
Radial flow, for drawing
the material to be mixed
from the top and the

Paddle stirrer
Ø 8, 10, 12, 16, 20cm
Ø 5cm
Two-bladed, blades open
with increasing speed.
For stirring in round ves-
sels with narrow necks.
Effect is similar to that
of a 4-bladed propeller
stirrer. Medium to high
speeds required.
Ø 5, 7, 7.5, 8, 11cm
Tangential flow, high
shearing rate at edges,
minimum deposits
on the vessel wall.
Used at low speeds.
Polymer reactions,
even distribution of
high mineral contents in
liquids. The ideal stirrer
for medium to highly
viscous fluids.
Ø 9.5cm
Ø 7cm
Tangential flow, minimum
turbulence, good heat
exchange, gentle
treatment of product.
Used at low to medium
speeds.
