Performance and Selection
The Element 345 reference includes 3K345. Final sizing should review flow, differential pressure, fluid properties, suction conditions and speed. Provide positive-displacement pressure protection and avoid dry running.
Stator Material Options
Available stator materials include Nitrile, Urethane, Natural Rubber, EPDM, Fluoroelastomer, and special application materials. Final material selection should be based on fluid compatibility, temperature, abrasion, and operating conditions.

Engineering Context for the 3AK345
The 3AK345 combines a three-stage arrangement with the 345 element at 340.0 GPM per 100 RPM and the K drive end rated to 54.0 HP per 100 RPM. The available source does not assign a verified pressure rating to the three-stage code, so no numeric pressure limit is inferred here.
