Product Description

HORIZONTAL END SUCTION CENTRIFUGAL FIRE PUMP

Horizontal End Suction Fire Pump

End suction centrifugal pumps are defined by the water's entry pathway. Water enters one side of the impeller, typically from "the end" on horizontal models. Unlike split casing types, the suction pipe and motor are parallel, simplifying orientation in mechanical rooms. Bearing support is provided by the motor or the pump power frame, making these ideal for specific water flow applications.

Performance Range
Electric Motor Fire Pump Unit
  • UL Listed & NFPA 20: Meets global safety and installation standards.
  • High Efficiency: NEMA Premium efficiency motors with TEFC enclosure.
  • Flow Range: 25 GPM to 5,000 GPM depending on configuration.
  • Control: Automatic start on pressure drop with manual override.
Electric Fire Pump
Diesel Engine Fire Pump Unit
Diesel Fire Pump
  • Independent Power: Ideal for areas with unreliable electrical grids.
  • Heavy Duty: Built for industrial and municipal fire protection.
  • Performance: Pressure ranges from 60-200 PSI.
  • Compliance: Tier 3/Tier 4 emission standards.
Multistage Jockey Pump

A jockey pump maintains the pressure in a fire protection system at an artificially high level. This ensures that the operation of even a single sprinkler head causes a detectable pressure drop, triggering the main fire pump.

Frequently Asked Questions
❓ What is an end suction fire pump?
It is a type of centrifugal pump where the suction is at one end of the shaft and the discharge is at the top. It is widely used for fire protection due to its compact design and efficiency.
❓ Are these pumps NFPA 20 compliant?
Yes, our fire pumps are designed and manufactured to strictly follow NFPA 20 standards for stationary fire protection pumps.
❓ Can I choose between an electric motor and a diesel engine?
Absolutely. We offer both electric motor-driven units for reliable grid-connected buildings and diesel engine-driven units for areas where power may be cut during an emergency.
❓ Why do I need a jockey pump?
A jockey pump maintains the pressure in your fire system to prevent the main fire pump from starting unnecessarily for small leaks or pressure fluctuations.
❓ What materials are used for the impeller?
We typically use bronze or stainless steel for the impeller to ensure corrosion resistance and long-term durability.
❓ Is the system suitable for sea water?
Standard units are for fresh water, but we can provide specialized materials (like Duplex stainless steel) for sea water applications upon request.
