VIBCO features both the One Piece Design and the All Steel Models. The one piece housing makes the unit low in cost but still maintaining high quality and long life. The one piece design is the choice for general applications. 
 

VIBCO’s steel units can take more abuse, operate longer with minimal lubrication, and have a longer life expectancy than the one piece design units. The all steel units should be used in continuous duty applications and where long life and high reliability is a must.
