End Suction Fire Fighting Diesel Pump In BD
Fire Fighting Diesel Pump UL-FM YNM
End Suction Centrifugal Fire Pumps
- These are end suction, single stage centrifugal pumps. These three pumps, YNM 525, YNM825 and YNM 1531 are used for flow rates ranging between 50 and 1250 gpm.
- The main pump dimensions are compatible with DIN 24256. The pump flanges are designed according to UL standarts ANSI/ASME B 16 Class 250
- The pump performances are compatible with UL standarts.
- The single suction, closed type impeller is dynamically balanced against the thrust by use of back wear rings.
- Shaft leak prevention is provided by 5 unit soft packing according to UL448 requirements.
- The parts inside the pumps that are in contact with water, such as bolts or bolt screw, are made of non-corrosive materials.

A fire pump is a part of a fire sprinkler system’s water supply and powered by electric, diesel or steam. The pump intake is either connected to the public underground water supply piping, or a static water source (e.g., tank, reservoir, lake). The pump provides water flow at a higher pressure to the sprinkler system risers and hose standpipes. A fire pump is tested and listed for its use specifically for fire service by a third-party testing and listing agency, such as UL or FM Global. The main code that governs fire pump installations in North America is the National Fire Protection Association‘s NFPA 20 Standard for the Installation of Stationary Fire Pumps for Fire Protection.
Fire pumps function either by an electric motor or a diesel engine, or, occasionally a steam turbine. If the local building code requires power independent of the local electric power grid, a pump using an electric motor may utilize, when connected via a listed transfer switch, the installation of an emergency generator.
