ACCA 2AK620 Progressive Cavity Pump
Two-stage 620 configuration using the K drive end for supported Moyno® 2K620 G1 installations.
The 2AK620 is a large two-stage 620 configuration with matching 10-inch process flanges. ACCA does not publish an Element 620 curve, so operating selection is based on the actual duty.

Confirm the complete nameplate before selecting replacement components.
2AK620 Dimensions and Installation Envelope
The 2AK620 measures 220.81 inches at A, 171.00 inches at B and weighs approximately 3,740 lb. It is roughly 80.62 inches longer at A than the single-stage 1AK620.

| Model | A | B | D | E | H | W | Suction | M | Discharge | M1 | Weight |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 2AK620 | 220.81 | 171.00 | 13.00 | 23.50 | 3.88 | 17.00 | 10 in | 16.00 | 10 in | 17.50 | 3,740 lb |
Dimensions in inches unless noted. Verify final installation dimensions against order documentation.
Performance Selection for the 620 Element
No neighboring element curve is substituted. Send required flow, differential pressure, fluid viscosity, solids loading, temperature, suction conditions and intended speed for application-specific review. Protect the system against closed-discharge operation and 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 2AK620
The 2AK620 pairs the 617.38 GPM-per-100-RPM 620 element with the K drive end rated to 54.0 HP per 100 RPM. Its two-stage 175 psi configuration combines very high displacement with increased pressure capability, so system suction and available power deserve close review.
