Varmeca Drive
The Varmeca drive brings 10:1 speed control,
constant torque output and total reliability to the
industrial environment. With no external wiring and
resin-shrouded electronics, humidity and vibration are
no threat. Inverter and motor are UL Approved and
sealed to NEMA 4X. Control could not be simpler,
with local forward/stop/reverse switching and a large
speed control knob calibrated in percentage of
maximum speed. The drive offers 230V and 460V
three phase power options, plus 115V and 230V
single-phase.

Mining
Used throughout the mining and mineral-processing world, Watson-Marlow
Bredel peristaltic pumps are the solution to many of the rigorous metering
challenges found in the mining industry including: reagent feed, shear sensitive
polymer metering for flocculation, abrasive lime slurries for pH control, or
corrosive cyanide for gold recovery. With a wide variety of drive configurations
available, including integral NEMA 4X washdown, TEFC and explosion proof,
Watson-Marlow Bredel offers the flexibility to meet the requirement of any
mining application. By changing either the bore diameter of the tube or the rpm
of the rotor, the rate of reagent feed will vary proportionally. And, each unit can
be interfaced to any digital or analog process control signal.
