ACCA 2AJ220 Progressive Cavity Pump
Two-stage 220 configuration using the J drive end for supported Moyno® 2J220 G1 installations.
The 2AJ220 extends the 220 pumping element to two stages with a J drive end and matching 10-inch process flanges. ACCA does not publish an Element 220 curve, so operating selection is duty based.

Additional Nameplate Configuration Codes
The remaining nameplate characters identify the body material, internal material, stator material, sealing arrangement, shaft/internal variation and rotor variation. Stator material options include Nitrile, Urethane, Natural Rubber, EPDM, Fluoroelastomer and special materials selected for the application. Confirm the complete nameplate before selecting replacement components.
2AJ220 Dimensions and Installation Envelope
The 2AJ220 measures 107.50 inches at A, 66.62 inches at B and weighs approximately 1,850 lb. Compared with 1AJ220, the two-stage configuration adds substantial length and weight while retaining the same J drive end and flange sizes.
| Model | A | B | D | E | H | W | Suction | M | Discharge | M1 | Weight |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 2AJ220 | 107.50 | 66.62 | 11.00 | 21.50 | 3.38 | 15.00 | 10 in | 16.00 | 10 in | 16.00 | 1,850 lb |
Dimensions in inches unless noted. Verify final installation dimensions against order documentation.
Performance Selection for the 220 Element
No neighboring curve is substituted. Send required flow, differential pressure, fluid viscosity, solids, temperature, suction conditions and speed for application-specific selection. Protect the system against closed-discharge operation 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 2AJ220
The 2AJ220 is a two-stage 175 psi J-drive configuration using element code 220. The J drive is rated to 28.0 HP per 100 RPM, but no verified displacement value for element 220 is present in the available source, so performance should be selected from the actual duty point.
