ACCA 6AK175 Progressive Cavity Pump
Six-stage 175 configuration using the K drive end for supported Moyno® 6K175 G1 installations.
The 6AK175 combines the 175 pumping element with the K drive end in a six-stage arrangement and matching 10-inch process flanges. It is longer and heavier than the four-stage 4AK175 while retaining the same K-drive and 175-element family.

Engineering Context for the 6AK175
The 6AK175 pairs the 175 element at 174.0 GPM per 100 RPM with the K drive end, rated up to 54.0 HP per 100 RPM. Its six-stage configuration is rated up to 450 psi, placing it among the larger-displacement high-stage G1 configurations covered in this series.
The combination of 175 displacement, K drive end and six-stage pressure class distinguishes this model from lower-stage 175 configurations. Final selection still depends on the required operating point, fluid properties, suction conditions and material compatibility.
