It does not relieve the user of their responsibility of using accepted engineering practices in the installation, operation, and maintenance of this equipment. Any further questions, contact ITT A-C Pump, (847) 966-3700. 2 DESCRIPTION The 8200 Series Centrifugal Fire Pumps are framed mounted pumps which feature – high efficiency, rugged construction, compact design, foot mounted volute and regreasable bearings. These features, along with the horizontal split case, make installation, operation and service easy to perform. OPERATIONAL LIMITS Unless special provisions have been made for your pump by ITT A-C Fire Pump Systems, the operational limits for 8200 Series Centrifugal Fire Pumps are as follows: MAXIMUM WORKING PRESSURE Listed on pump nameplate. SEAL OPERATING LIMITS PACKING PH Limitations 7-9; Temperature Range 0 to +200°F For use on open or closed systems which require a large amount of makeup water, as well as systems which are subjected to widely varying chemical conditions and solids buildup. PUMP IDENTIFICATION There are two identification plates on each pump. The pump rating plate gives identification and rating information. Figure 1 shows an example of a typical Rating Plate. Permanent records for this pump are referenced by the Serial Number and it must, therefore, be used with all correspondence to order all spare parts and replacement parts. The fourth digit indicates the specific pump on orders for more than one pump. For example, if an order called for six pumps, all pumps would have the same first three sets of digits and the last digit will change to identify each of the six. (e.g. 03-123456-0101, 03-123456-01-02, etc.) The frame plate, shown below in Figure 2, gives information concerning the bearings and their lubrication. The inboard and outboard be...
