ACCA 1AK800 Progressive Cavity Pump
Single-stage 800 configuration using the K drive end for supported Moyno® 1K800 G1 installations.
The 1AK800 is a large single-stage G1 pump with a K drive end, 12-inch suction flange and 14-inch discharge flange. ACCA does not publish an Element 800 performance curve, so selection is duty based.

Performance Selection for the 800 Element
No neighboring element curve is substituted. Send flow, differential pressure, fluid properties, suction conditions and intended speed for application-specific review. For this large pump, base condition, lifting, pipe support and drive alignment should also be reviewed carefully.
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 1AK800
The 1AK800 is the largest-displacement single-stage configuration in this G1 set, with the 800 element documented at 790.0 GPM per 100 RPM and the K drive end rated to 54.0 HP per 100 RPM. Its 87 psi class makes it a high-flow rather than high-pressure configuration.
