Nfpa 20 Listed Best Price Single Stage Electric End Suction ...
NFPA 20 end suction fire pumps are compact, reliable, and cost-effective solutions for fire protection, generally limited to capacities of 1500 gpm or less. These horizontal shaft pumps are often used where space is limited and must meet strict requirements for suction piping (e.g., eccentric reducers, flat side up) to prevent air pockets.

Key NFPA 20 End Suction Pump Considerations: 
  • Capacity: Typically suitable for low to medium-capacity systems, up to 1500 gpm.
  • Installation: Must be installed horizontally.
  • Pipe Fitting: Requires straight pipe length into the suction, at least 10 times the pipe's diameter.
  • Component Compliance: Must be listed for fire service, including electric or diesel drivers.
  • Cooling Systems: While the pump is for fire water, NFPA 20 Compliance Made Simple for End Suction Fire Pumps notes that proper selection ensures it handles the hydraulic demands. 
Key Requirements & Design Considerations: 
  • Pump Suction: Must be installed with an eccentric reducer with the flat side on top to avoid air pockets.
  • Performance Points: The system must meet three non-negotiable points: churn, rated, and 150% of rated capacity.
  • Pump Location: The pump room should be heated to at least 40°F (4°C).
  • Pressure: The pump must be rated to meet the pressure needs, with a maximum of three pumps allowed in series.
  • Testing: Performance tests are mandatory, as described in NFPA 20.
  • Maintenance: Regularly scheduled inspections and testing must be performed per NFPA 25 or manufacturer specs.
