Pump System Information Manual 4-10-2026.pdf

This document is an Information Manual for the Puerto Rico National Cemetery's Well Water Supply and Booster Pump System.

The system comprises two wells (approximately 500' and 350' deep) with 2" galvanized well pipe, both supplying an 80,000-gallon water holding tank via an alternating relay control mechanism. The wells are equipped with A.Y. McDonald pumps (model #24750T32, 7.5 hp, 230 volt/3 phase), with both pump heads located inside vaults containing check valves and unions. An alternating relay in the well pump control panel automatically switches between the two pumps as the float-operated switch in the holding tank calls for water. The system is designed to maintain 60 psi irrigation pressure through a Grundfos CR 45-2 booster pump that supplies water to four Kifco Hose Reels fitted with 0.45 nozzles. System capacity provides 8 to 9.25 hours of continuous operation at 60 psi before the holding tank requires refilling. A high-level beacon alerts staff if water exceeds safe levels.

Critical operational requirements include maintaining flow rates at or below 75 GPM to prevent equipment damage, verifying sufficient water in the tank before operating the booster pump, and allowing up to 90 minutes for the booster pump to establish prime and full dynamic pressure before irrigation use. The manual provides detailed procedures for accessing municipal water as backup, resetting the booster pump after dry-run conditions, and managing drought operations. Annual preventative maintenance includes testing well pumps individually, inspecting check valves, servicing float switches, transformer maintenance, and cleaning the 80,000-gallon holding tank bi-annually. Quarterly maintenance is required for the booster pump, variable frequency drive (VFD), and system inspections.
