MD Series

Features & Benefits:

• Available in 7 heights, from 7 3/8″H to 23 1/2″H; and 7 flange diameters from 4″ to 16″.
• Valve housing cast in North America; ensures superior strength and solidification of housing’s metallurgy.
• CNC-machined components and housing provide precision tolerances; eliminates axial shaft movement, extends maintenance cycles.
• Outboard bearing design protects bearings in high-temperature and high-PSIG applications; removes bearings from direct path of damaging contaminants.
• Easily manages pressure differentials up to 15 PSIG; with super-duty series up to 22 PSIG.
• Excellent performance in high-temperature applications up to 750°F.
• Cast iron housing.
• 8-vane rotor with beveled tips and sides.
