Pump Selection & System Efficiency Design Template

At its core, the template formalizes the iterative process of matching pump characteristics—such as head, flow rate, efficiency, NPSHr, and power consumption—to the system’s resistance curve (governed by pipe friction, elevation changes, and fittings) and operational duty cycle (e.g., constant vs. variable flow, intermittent vs. continuous service). It emphasizes system-level thinking: rather than optimizing the pump in isolation, it evaluates how pump selection impacts motor sizing, control strategy (e.g., throttling vs. VFDs), piping layout, and overall energy use over the asset’s lifetime. Key inputs include fluid properties (viscosity, specific gravity, temperature), system design criteria (minimum/maximum flow, pressure requirements, redundancy needs), and sustainability goals (e.g., ISO 5198 or HI 40.6 compliance, ENERGY STAR benchmarks). The output includes validated pump model recommendations, efficiency metrics (e.g., Wire-to-Water Efficiency), lifecycle cost analysis (LCCA), and implementation notes covering installation, instrumentation, and maintenance access. Advanced versions incorporate digital twin readiness—embedding data tags for real-time monitoring, predictive maintenance triggers, and integration with building management systems (BMS) or SCADA platforms.
