MECHANICAL DIMENSIONS
The Controller/Pump series of instruments are enclosed in a modular
housing for maximum protection. The dimensioned illustrations show
the layout of the Controller/Pumps and how they utilize the one-piece
polypropylene, injection-molded housing. Since there are no joints or
screws holding different sections of the housing together, the case is
extremely rugged and sturdy.
