So, is this just one section, or is it the whole shebang?

This Permco 257 section is a single component, designed to be part of a larger hydraulic system.

Question by: Randy B on Jan 11, 2026, 7:28 AM

what exactly is a "section" on one of these permco 257 pumps? trying to figure out if this is the whole unit or just a part of it

Answer by: Customer Support on Jan 13, 2026, 6:16 AM

A section refers to one individual pumping element within a multi-section gear pump assembly. The Permco 257 is a sectional pump design, meaning the full unit is built by combining sections together. So no, this is not a complete standalone pump on its own. It gets assembled with other sections to make up the full pump configuration you need for your application.
