WATERFALL

Fire Pumps by Waterfall Pumps Manufacturing are certified by Underwriters Laboratories (UL) and approved by Factory Mutual (FM). The full range includes Horizontal Split Case, End Suction, and Vertical Turbine fire protection pumps. These pumps are available in both electric motor and diesel engine driven configurations.

Additionally, Waterfall Pumps Manufacturing offers a containerized fire system, known as the WF Fire Pump House (Pre-packaged Systems). These systems can be customized to meet specific site requirements or client preferences, all while adhering to industry standard specifications.

1 – HORIZONTAL SPLIT CASE FIRE PUMP

Horizontal Split Case Fire Pumps typically offer wide range of hydraulic

coverage while operating at higher efficiencies. Rugged, heavy duty

construction coupled with superior design features make this type of pumps very reliable while requiring low maintenance. Fully enclosed double suction impellers practically eliminate axial thrust while radial load is equally shared by the bearings located at each end of the shaft. The simplicity of design allows service without disturbing piping at site. It can be driven by either an electric motor or a diesel engine with a full range of options and accessories available to comply fully to NFPA standards. Heavy fabricated steel base plates are used to mount the pump and driver along with flexible coupling which connects driver to pump. Horizontal Split Case Fire Pumps are ideal when the source of water is located above the ground as it provides

a positive suction pressure to the pump at any performance point.

PUMP PERFORMANCE

  • Flow ranges from 300 GPM up to 3500 GPM
  • Pressure ratings from 81 PSI up to 345 PSI

DESIGN FEATURES

  • Underwriters Laboratories (UL) – 448
  • Factory Mutual (FM) – 1311
  • NFPA 20

 

2- END SUCTION FIRE PUMP

End Suction Fire Pumps are engineered to last with a precision-cast,

dynamically balanced and enclosed impeller that minimizes the vibration and maximizes bearing life. Due to its back-pull-out design, the complete bearing assembly including impeller and casing cover can be dismantled without

removing the volute casing from the pipe system. It can be driven by either an electric motor or diesel engine with a full range of options and accessories available to complete the NFPA-compliant fire pump. Heavy fabricated steel base is available to mount the pump and driver along with flexible coupling connects driver to pump. End Suction Fire Pumps are ideal when the source of water is located above the ground as it provides a positive suction pressure to the pump at any performance point.

  • Flow ranges from 50 GPM up to 1000 GPM
  • Pressure ratings from 80 psi up to 309 psi
  • Underwriter Laboratories (UL) – 448
  • Factory Mutual (FM) – 1319
  • NFPA 20

3- VERTICAL TURBINE FIRE PUMP

Vertical Turbine Fire Pumps are specially designed to pump from water source located underground or below deck, where there is no possibility to install a horizontal fire pump. The flexibility of its design allows the use of a wide range of materials. Vertical Turbine Pumps use multi stage configuration to meet the specific requirements of the user and can be customized according to specific in­stallation requirements. The space saving vertical design minimizes the floor space requirements. It can be driven by either an electric motor or diesel engine with a full range of options and accessories available to complete the NFPA-compliant fire pump. Waterfall vertical turbine fire pumps are available in a wide range of flow rates, pressure heads and material of construction.

PUMP PERFORMANCE

  • Flow ranges from 150 GPM up to 2000 GPM
  • Pressure ratings from 49 psi up to 402 psi

DESIGN FEATURES

  • Underwriter Laboratories (UL) – 448
  • Factory Mutual (FM) – 1312
  • NFPA 20
