CMA-150 Disperser

The CMA series is a 1.5 or 2 HP, variable speed, direct drive lab/small production disperser designed for use in 5 gallon pails. It is VFD inverter controlled, and uses either a 3” or 4” Cowles style sawtooth impeller. This is an economical, heavy duty disperser that provides full dispersion speed. Available with either a TEFC motor, or explosion Proof motor, it runs off standard 115 or 230 volt single phase AC power for the 1.5 HP machine and 230V single phase on the 2 HP machine. The 14” pneumatic lift is standard, but this unit may be ordered with a hand crank lift mechanism.
