A.02.05 Limited Source Determinations - Unwatering Pump Parts FINAL_Redacted.pdf

This document is a Limited Source Justification for purchasing replacement parts for a Flowserve Model 26ELM-1 pump, Serial number 1907MS006901-1, at the Little Goose Lock and Dam, which is operated by the U.S. Army Corps of Engineers, Walla Walla District.

The justification states that the Flowserve pump is a sole source item, as the parts are only available from the original equipment manufacturer, Flowserve. The Corps intends to purchase the replacement parts through Solicitation W912EF24Q0046. The parts are required to maintain the pump, which is critical to the unwatering operations at the lock and dam. No other pump models or manufacturers are considered acceptable substitutes. The justification provides details on the pump's operational history, the criticality of the unwatering function, and the lack of available alternatives. The Corps has determined that this is the only practical source to meet the Government's minimum needs.
