Performance and Selection
The Element 022 curve is the family performance reference. Confirm the complete 4F022 configuration and actual duty before final selection. Review flow, differential pressure, fluid properties, 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 4AF022
The 4AF022 keeps the 022 element at 21.89 GPM per 100 RPM but moves to the F drive end rated to 5.9 HP per 100 RPM. This provides greater drive capacity within the four-stage 350 psi family than the E-drive 022 configuration.
