THE OUTCOME Today, the VPGC’s sanitation crew cleans the plant in the same amount of time with 300 psi less pressure, and the sanitation crew has not reported any noticeable decrease in pressure. VPGC’s decision to reduce system pressure along with the high efficiency operation of the Grundfos Hydro HP has reduced energy consumption of the plants high-pressure system by more than 50%, according to Grundfos Sales Engineer Tommy Pierce. Plant energy usage will be reduced by more than 600,000 kWh per year – the equivalent to more than $50,000 a year. Pierce says with energy savings and reduced maintenance costs, VPGC can expect a ROI of less than two years on the new pump system. VPGC Engineering Manager Phil Miller says, “Grundfos is the first pump company in 20 years that has presented me with an alternative to the pitot tube pumps. The controls are a lot more bulletproof than I thought they were. They only run when we need the water. They go up and down with our flow way better than our other system. I am not even looking back.” The Grundfos Hydro HP system is saving VPGC more than $50,000 a year in energy costs from the previous pitot tube pump.
