MS-40H Hydraulic Mixer General Information

MS-40H HYDRAULIC MIXER — GENERAL INFORMATION

GENERAL

The STOW MS-40H plaster and mortar hydraulic mixer is shipped completely assembled and has been factory tested.

The drum batch capacity of these mixers is between 3.5 and

4.0bags. With proper care, they will give continuous service year-after-year.

This mixer can be powered by either gasoline or electric motors. The power from the engine rotates a hydraulic pump which provides hydraulic fluid to a directional control valve. The control valve directs fluid to the hydraulic motor which causes the paddle shaft to rotate. This type of hydraulic pump design provides high mixing torque and eliminates V-belts, pulleys ect.
