How much is a 10" x 96" long flex coupling? Well, two of them....
Any cost overruns could be covered by a quarter slot, mount a saddle to it (western) and hit the button! George L. Church, Jr., CET Rowe Sprinkler Systems, Inc.

BTW here is the actual spec section Mount fire pump(s) on vibration spring-type isolators. Provide hot dipped galvanized housings and neoprene coated springs. Minimum horizontal stiffness shall equal to 75 percent vertical stiffness with working deflection between 0.3 and 0.6 of maximum deflection. Provide with leveling devices with minimum 1/4 inch (6 mm) thick neoprene sound pads and zinc chromate plated hardware. 1. Sound Pads: Size for minimum deflection of 0.05 inch (1.2 mm) and meet requirements for neoprene pad isolators. 2. Restraint: Provide heavy mounting frame and limit stops.
