Diesel Tanks. When you design or install a fire protection system, you hope it goes unused. In addition to the existence of pumps that will operate at full performance in emergency situations, providing the necessary controls and regular maintenance also plays a critical role. RP's Fire Systems offer longer life, higher efficiencies, less downtime and lower maintenance costs. Horizontal split case fire pumps (UL / FM Approved FLHC series). In practice; however, I have yet to find a manufacturer who is agreeable to doing this.
It is one of the indispensable prerequisites that many materials, from the wheel to the lantern ring, have absolute corrosion resistance. All above equipment except fuel supply tank and fire pump controller are mounted on a common base frame. The bearings must have a working capacity of 5000 hours at maximum load. Less pipe work and fewer valves, as one pump could eliminate the need for some control valves and pressure reducing devices. All components within the pumps are independently approved and tested ensuring the product meets the expected high quality. In place of, or, in addition to the hose valve header with hose valves, we offer a complete line of UL/FM approved flow meter which can adequately test the fire pump performance in cases of liquid water supply. Evaluating fire pumps and engines.
The modular design of the fire pump set not only keeps installation easy and simple, but enables each fire set module to be tailored to meet the fire systems specific requirements. 3, which must be provided by the OEM. NM Fire is the first member of NFPA from Chinese pump manufacturers.
