Tri-Rotor Pump model 40A is the second smallest in the family of Tri-Rotor solid head pumps that provide constant flow rates.  This relatively low cost pump is perfect for simple fluid transfer such as loading and unloading drums, totes, tanks, and trailers.  The pump serves a wide range of industrial markets and applications.  Examples of the 40A model’s diverse applications include pumping waste water, colored ink, rubber cement, blackstrap molasses, lubricating grease, varnish, resin, and latex.

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 40A 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.
