Tri-Rotor Pump model 100CX, which shares common components with model 80BX and model 120AX, is in the second to largest family of Tri-Rotor bypass head pumps that incorporate an internal relief valve and provide constant flow rates.  The oversized relief valve bypasses full flow directly from the discharge to the suction port when the set discharge pressure is achieved.  Discharge may be restricted or blocked entirely without shock or chatter.  The pump serves a wide range of industrial markets and applications.  Examples of the 100CX model’s diverse applications include pumping No. 2 fuel oil, tall oil, transformer oil, shortening, fatty acid, acetate, polymer, and synthetic detergent.

The pump is designed with side suction and top discharge flanged ports and is available in both clockwise (CW) and counterclockwise (CCW) rotations for pump installation flexibility.  Materials of construction for the 100CX model include Iron Fitted, All Iron, Bronze Fitted, or All Bronze configurations.  Two drain plugs, located on the shaft housing, are provided with every pump.
