About this file
This document appears to be Technical Specifications for a procurement action by Yellowstone National Park (YELL) to replace existing water pumps and motors at the Lake Village location. YELL requires the procurement of 2 pumps, 2 motors, and 2 electric check pump control valves to be installed on the pump discharge to minimize pressure surges. The existing pumps have a capacity of 280 gallons per minute (GPM) and a total dynamic head (TDH) of 132 feet. The new pumps and motors must meet these specifications and be NSF 61 compliant for potable water applications. The Technical Specifications provide detailed requirements for the pump and motor components, as well as the control valve specifications. This procurement is associated with the federal contract opportunity YELL LAKE TREATED WATER PUMPS, Solicitation Number 140P1424Q0105, issued by the Department of the Interior National Park Service Intermountain Region.

Technical Specifications Yellowstone National Park (YELL) is procuring a Quantity 2 Pumps and 2 motors to replace existing Hydro Flow Treated Water Pumps and Motors at Lake Village (see attached for Hydro Flow specs).
YELL also requires procurement, quantity of 2 size 4-inch electric check pump control valves to be installed on the discharge of the water pumps to minimize pressure surges associated with pump starting and stopping. Control valves will be self-contained, differential piston actuated and utilize line pressure for operation. The control valve will be independently adjustable for normal opening, normal closing, and emergency closing speeds so the valve can be “tuned” to minimize surges under all operating conditions. Control valve will need to interface with existing motor control center.
Control Valves will be brand name or equal to: Size 4-inch GA Industries 1730DCE Electric check valve w/ stop check piston 125# flanges, 316SS fasteners replacement for s/n 810302 Original pumping capacity was 280 gallons per minute (GPM) with a total dynamic head (TDH) of 132 ft. Currently YELL has a diesel pumping bypass option online to augment the high demand summer season. Diesel power bypass pumping is not a viable option for long term summer use and winter operations.
