7CLC-6_Datasheet.pdf

This is a pump datasheet and project specification document for the City of Wheat Ridge, Colorado, detailing the replacement of an existing pump system at Prospect Park. The project requires installation of a new 7CLC (6-stage) turbine pump with a 10 hp motor operating at 1800 rpm to support the park's irrigation needs and water features. The pump specifications include a 5.25-inch diameter impeller, 1750 rpm lineshaft speed, and performance capabilities of 203 US gallons per minute at 134 feet of head with 80% efficiency. The project scope encompasses removal of the outdated existing pump system, installation of the new pump unit, and all associated electrical and plumbing work. The pump is rated for a maximum operating temperature of 120°F and pressure of 415 psi gauge, with a shutoff head of 205 feet. Design specifications indicate the pump was selected from Goulds Lineshaft 60 Hz catalog (Version 3.11) based on maximum power rating on the design curve, with performance evaluation data provided across multiple flow rates ranging from 86.8 to 260 US gallons per minute.

The datasheet provides comprehensive performance characteristics including efficiency ratings between 62% and 79.8% across the operating range, net positive suction head requirements ranging from 1.92 to 6.63 feet, and power consumption from 6.21 to 8.71 horsepower. The pump configuration specifies discharge sizes of 4, 5, or 6 inches with a 7.13-inch bowl size and standard vertical turbine construction. No specific contract response date, award date, or contract term information is provided in this technical datasheet. Pricing terms, funding sources, and procurement set-asides are not addressed in this pump specification document.
