Performance and Selection
The Element 345 reference includes 2K345. Final sizing should review flow, differential pressure, viscosity, solids, temperature, suction conditions and speed. Use 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 2AK345
The 2AK345 uses the same 340.0 GPM-per-100-RPM 345 element but moves to the K drive end rated to 54.0 HP per 100 RPM. This gives the two-stage 175 psi configuration substantially greater drive capacity than the J-drive version.
