Confirmed. The supplier part number on this unit is 574-00605-4, and it carries the Permco designation 257 SEC 4-B B W/DR. Cross-referencing that number against your existing pump or system documentation before ordering is always a solid move, and that number should match up cleanly with Permco's own part records.

What exactly does the "W/DR" stand for on this Permco pump?

That suffix refers to the configuration, indicating that this particular 257 series Permco pump is built with a specific valve and drive arrangement.
