80 GPM Internal Bypass Relief Valve Pump – Tri-Rotor Model 80BX
Click image to enlarge
Tri-Rotor Pump model 80BX, which shares common components with model 100CX and model 120AX, is in the second to the largest family of Tri-Rotor bypass head pumps that incorporate an internal relief valve and provide constant flow rates. The relief valve bypasses 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 80BX model’s diverse applications include pumping rayon acetate, butadiene, bunker C fuel oil, invert sugar, castor oil, and hydrocarbon compound.
The pump, available in both clockwise (CW) and counterclockwise (CCW) rotations, is designed with two threaded suction ports (side and top) and two threaded discharge ports (side and top) for the ultimate in installation flexibility. Standard configuration is side suction and top discharge. The other two ports are plugged with easily-moved pipe plugs. One of these unique pumps could even be installed to deliver two different compatible fluids to two different locations. Materials of construction for the 80BX 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.

As with all Tri-Rotor pump models, the 80BX is available with a Steam Jacketed option for fluids requiring to be heated or cooled in order to be pumped. Tri-Rotor also offers an interesting option for its’ 80BX bypass head design: a Reduced Stroke Pump Head. With this option, the pump can be designed to target a specific flow rate at a percentage of full flow.
