SA-EP Piston Vibrators from HVI will bring your problems back down to size!  SA-EP Piston Vibrators are the most powerful continuous duty vibrator available for their size.  These miniature powerhouse vibrators will keep your production at its peak by eliminating wasted man-hours and unnecessary maintenance.  The linear shock action vibration of the SA-EP series puts an end to bridging and plugging, and keeps your material flowing in small bins, hoppers, and chutes.  The SA-EP Piston Vibrators feature rugged steel bodies with hardened end heads and heat-treated pistons which are precision ground and hard chrome plated. Their full porting insures quick startup and smooth operation, making the SA-EP the simple choice for material flow problems in small places.
