40AX

Tri-Rotor Pump model 40AX is the second smallest in the 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 40AX model’s diverse applications include pumping liquid sugar, mineral spirits, fish oil, palm oil, linseed oil, calcium chloride, hot vegetable oil, and water based paint.

The pump is designed with side suction and top discharge threaded ports and is available in both clockwise (CW) and counterclockwise (CCW) rotations for pump installation flexibility.  Materials of construction for the 40AX model include Iron Fitted, All Iron, Bronze Fitted, or All Bronze configurations.  One feature of the pump is that the shaft housing (or stuffing box) is integrated into the pump body, reducing the number of parts and the time required for maintenance.
