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.

Specifications of Tri-Rotor Pump Model 40A:
  • Flow rate:  8 to 42 GPM
  • Viscosity range:  4 to 21,625 cPs (40 to 100,000 SSU)

As with all Tri-Rotor pump models, the 40A 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’ 40A solid 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.
