Clearances for energized electrical equipment per NFPA 70 (National Electrical Code). Proper orientation of the pump relative to the suction piping to ensure established minimum distances to parallel fittings. Electrical systems for fire pumps are governed specifically by NEC Article 695. This article includes all of requirements for normal and alternate sources of power for fire pumps. NFPA 20: Standard for the Installation of Stationary Pumps for Fire Protection protects life and property by providing requirements for the installation of fire pumps to ensure that systems will work as intended to deliver adequate and reliable water supplies in a fire emergency.
Nfpa 20 Fire Pump Installation
Fire pump intakes are connected to underground public water supply piping, or a tank or reservoir located onsite, to provide water flow at a higher pressure to the sprinkler system risers and hose standpipes. Fire pumps are activated when the water pressure in the system drops below a certain threshold. Fire pumps are an essential part of most fire protection systems, as they allow for taller buildings, smaller piping and higher pressure and flow rates in systems. Incorrectly sized or selected pumps can result in not enough pressure or flow being created, which can cause several problems: Systems function incorrectly. 1. A circuit breaker designed for installation in a normal power supply circuit, upstream of thecircuit breaker in a fire pump controller (see diagram 2) should be selected with aninstantaneous trip setting at 21 times of the full-load current and with thermal/locked rotorovercurrent protection setting at 350% of the motor full-load current. 2. The items below serve as a basic checklist of additional coordination items not previously discussed. Points on the fire protection system monitored by the fire alarm system such as fire pump status, control valve positions, waterflow and tamper switches. The approved audible alarm device required per IBC 903.4.2.

Centrifugal Fire Pumps: Centrifugal fire pumps are widely used due to their efficiency and reliability in supplying water to fire suppression systems. Our experts are well-versed in the installation of centrifugal fire pumps, ensuring proper alignment, piping connection, and integration with the existing fire protection infrastructure. If you follow NFPA 20, "Standard for the Installation of Stationary Pumps for Fire Protection," then you'll want to install emergency lighting in the pump room per Sec. 5.12.4 and remote monitoring per Sec. 10.4.7.1. Even if it's not required, a monitoring system is a sound idea.
A fire pump is any type of purpose-driven pump used within a fire protection system. It can be driven by diesel engines, electric motors or even steam and is used to provide increases in water pressure to meet the design requirements of a fire protection system. Fire pumps do not create a water supply. In addition to addressing the more obvious components that comprise a fire pump installation - such as the fire pump, driver, controller, and pump room-careful attention also needs to be given to the piping leading to, from, and around the pump and the equipment associated with that piping.

5. INSTALLATION Fire water pump sets and control systems should be installed, and accepted, in accordance with NFPA 20. Failure to install the supplied NAFFCO fire pump set fully in accordance with the NFPA 20 will void the equipment warranty. Proper ventilation and drainage system shall be provided for fire pump room. 5.1. Foundation The primary design references for fire pump installations are NFPA 20 Installation of Centrifugal Fire Pumps, Unified Facilities Criteria (UFC) 3-600-01 Design: Fire Protection Engineering for Facilities. The Designer will coordinate this specification section with any applicable contract sprinkler system.
