Walker Process offers a cover mounted vertical shaft mixer by STAMO that provides a low energy solution for through maintenance free mixing for anaerobic digesters.

The impellers are fabricated from stainless steel and designed to optimize the most effective glide ratio and lowest power usage with the highest pumping capacity.

The Agitator is driven through a hollow shaft reducer and the shaft is supported by a secure base that supports a radial bearing.

The main shaft is sealed with a labyrinth water seal that positively prevents leakage of gas from the digester. A monitoring device provides remote indication of low water level in the seal.

All product contact surfaces are stainless steel.

Controls include automatic reversal of shaft rotation to minimize debris accumulation on the impellers.
