About this file
This is a Draft Specifications document for the procurement of a replacement wastewater and hazardous solids handling lift station pump for Flagg Ranch Lift Station at Grand Teton National Park. The government seeks one Myers 4VHX75M403 Hazardous Solids Handling Wastewater Pump with precise specifications to match the existing lift station configuration. The pump must feature a 7.5 HP motor with 3-phase, 200V, 60 Hz power requirements, 1750 RPM, and a full load amperage of 30 amps. Key specifications include a maximum hydraulic head of 85 feet, maximum capacity of 725 GPM, maximum liquid temperature rating of 140°F, and capability to pass full 3-inch spherical solids. The pump must include an oil-filled motor for heat dissipation and bearing lubrication, heat sensor for overtemperature protection, double tandem mechanical shaft seals with oil-filled seal chamber, cast iron body construction with 4-inch 125-pound ANSI flange discharge, and UL listing for Class I, Division 1, Group D hazardous locations.
The delivery location is Moose Warehouse, Grand Teton National Park, 103 Headquarters Loop, Moose, Wyoming 83012, with a required delivery date no later than May 1, 2026.
