NEPA 20 System
To meet the recommendations of the standards of the National Fire Protection Association as published in their Pamphlet 20,
current edition, certain accessories are required for all fire pump installations. They will vary, however, to fit the needs of each
individual installation and the requirements of the local insurance authorities. Sterling provides a wide range of fire pump fittings
which include: concentric discharge increaser, casing relief valve, eccentric suction reducer, increasing discharge tee, overflow
cone, hose valve head, hose valves, hose valve caps and chains, suction and discharge gauges, relief valve, automatic air release
valve, flowmeter, and ball drip valve. No matter what the requirements, Sterling has a complete line of accessories available and
can satisfy the requirements of each installation. The charts reproduced below graphically illustrate the many accessories as well as
the optional drives that are available with all Peerless fire pumps and packaged systems.
