(A) The pumping unit is comprised of a small tier IV emissions 38 HP three cylinder (air cooled) Hatz diesel 3L41C “Silent Pack” design with a noise dampening enclosure, and a residential silencing muffler. The power package includes a Techno drive Power Tak-Off, Murphy Shutdown panel, and 12 volt battery with cables. The entire package is mounted on a base plate which contains a30 gallon fuel tank and battery. The pump and driver are connected through a flexible, electrometric coupling, and covered in an OSHA guard. The 2K6x4-13″ Durco Process pump unit can operate at approximately 1,000 gpm to 1,400 gpm (based on the size of main, distance between hydrants/blow-offs and filter loadings). This equates to being able to flush a maximum of 12″ mains at 3 ft/sec velocity, and 10″ mains at the desired 5 ft/sec velocity.
