Attachment 3 - Pump Performance Graph.pdf

This document is a technical specification sheet containing performance curves and product documentation for a centrifugal pump model SP3215X20XE. The performance curves chart illustrates the relationship between flow rate (measured in gallons per minute, or GPM) and total dynamic head (TDH, measured in feet of water) across seven operating speeds: 3450 RPM, 2850 RPM, 2550 RPM, 1725 RPM, 1500 RPM, 1225 RPM, and 3450 RPM at 115V. The curves demonstrate that as flow rate increases, the head capacity decreases across all speed settings, with the highest speed (3450 RPM) producing maximum head output of approximately 90 feet at zero flow, declining to roughly 150 GPM at zero head.

The document includes photographic evidence of the actual pump unit and its nameplate specifications. The nameplate identifies the pump as a Hayward Industries product with specific model designations and operational parameters. This technical documentation appears to be an attachment to a federal contract file (reference FA460826QS026) and serves as supporting specification material for procurement purposes. The performance curves enable potential bidders and contracting officials to evaluate pump capabilities against specific project requirements regarding flow and pressure specifications.
