About this file
This document contains plans for upgrading pumps at the McNary Lock and Dam pump station on the Columbia River in Oregon and Washington. The plans call for replacing two existing pumps with new pumps that match the existing mounting arrangement and can pass through the existing floor opening. The new pumps must be compatible with the existing electrical system and control set point. They shall have expansion couplings to connect to the existing discharge piping and allow for limited axial and angular misalignment. Additional requirements include showing dimensions, ratings, curves and settings on the plans and at the pump station. The solicitation number for the pump upgrade is W912EF23B0002, issued by the Department of the Army Corps of Engineers Walla Walla District.
