 These
portable Stepless Variable Speed Mixers have the same proven
components as our constant speed mixers. - A firm mounting
assembly with rapid acting universal ball and socket swivel
clamp, adjustable through 360 degrees in a horizontal plane,
tilts back 100 degrees to clear tank. Broad clamp face to
grip tank edge. Accurate sleeve coupling. Precision shafting.
Balanced, high performance propellers. Geared models offer
heavy duty gears and wide bearing span for shaft support.
MOTORS
Shunt wound continuous duty, DC motors are used. Totally enclosed
and explosion proof motors have a 75 degree C rise above ambient
at full load, and Class B insulation. 120 volts in fractional
sizes, and 120 or 240 volts integral.
CONTROLS
For the unltimate in speed control, a shunt wound motor with
a full wave transistorized silicon rectifier is used. These
provide full range speed from 0 to 1725 RPM, or 0 to 430 RPM
in the geared models, with full rated torque over the whole
range. Where constant pre-set speed under varying load is
desired, this combination is suggested. Portected against
overload.
Full wave controls with various features, for operation from
230 volt, 60 cy., 3 phase current supply, require separate
rectifier assembly in wall mounted cabinet. Attached or remote
operator station, any enclosure. Higher voltages reduceable
by transformer.
Variable speed drives are available for vertical flange mounted
or side entering mixers to 25 horse power. Wetted parts in
carbon or stainless steels, monel, or coated, as required.
