Applications:

The FLBS fire pump-sets are used in small capacity, diesel engine or motor driven fire-fighting applications for supplying water to fire hose reels, fire hydrants or sprinkler systems in areas which are prone to the hazards of fire.

The typical applications are as follow:
Commercial complexes & Highrise buildings
Petrochemical industries and Gas plants
Airports and ports
Jetties
Marine applications
Power stations and transformer stations
Chemical industries
Manufacturing plants
Fire-work industries
Warehouses / Godowns

There fire pumps typically consist of the following equipment:

Single-Stage End-Suction pump
Electric motor or Diesel Engine
Cooling system for Diesel Engine
Fuel system for Diesel Engine
Battery for Diesel Engine electric start
Exhaust system for Diesel Engine
Diesel Engine / Electric Motor Fire pump controller
Suction and Discharge pressure gauges
Casing Relief Valve for Motor Fire pump
Base frame

All above equipment except fuel supply tank and fire pump controller are mounted on a common base frame.

We along with Lubi can also supply packaged fire pumping system with all required accessories ready for site installation.

UL Listed & NFPA 20 Compliant

Strict adherence to UL Listed and NFPA 20 fire pump standards ensures optimal reliability and safety in critical fire suppression systems. The careful material selection and robust design offer dependable service across industrial, commercial, and public buildings.

Efficient Back Pull-Out Construction

The back pull-out design simplifies routine maintenance and repair, as the rotating assembly can be removed without disturbing the connecting pipework. This feature minimizes downtime and maintenance costs for installers and facility managers.

Versatile Applications and Compatibility

With options for electric or diesel drive and a range of inlet and outlet diameters (50 mm to 250 mm), these pumps are ideal for sprinkler, hydrant, and deluge systems. The red epoxy coating provides corrosion resistance essential for fire safety equipment.

FAQs of Fire Fighting Pumps Back pull-out - UL Listed NFPA 20 Design:

Q: How should the pump be primed before operation since it is not self-priming?

A: This pump requires a flooded suction or must be manually primed before starting because self-priming is not available. Ensuring the pump casing and suction line are filled with liquid prevents damage and supports optimal performance during fire emergencies.

Q: What types of seals are available for these fire fighting pumps?

A: These pumps are available with either gland packing or mechanical seals. The choice depends on operating preferences, fluid characteristics, and maintenance requirements, both providing effective leakage control for continuous-duty operation.

Q: When should I consider using a diesel engine as the power source?

A: A diesel engine power source is recommended when electrical supply reliability is uncertain, or when local regulations require a backup power option for fire protection equipment as per NFPA 20 guidance. Diesel engines provide a standalone and dependable alternative.

Q: Where can these pumps be installed?

A: These fire fighting pumps are suitable for installation in industrial sites, commercial complexes, sprinkler and hydrant systems, and any environment requiring reliable fire protection. Their robust design withstands varied environmental and operational conditions.

Q: What maintenance process is required for the back pull-out pump design?

A: The back pull-out configuration allows the rotating assembly to be withdrawn without disconnecting the pipework, making routine inspection, seal replacement, or bearing maintenance straightforwardreducing downtime and simplifying service logistics.

Q: How does the flexible coupling benefit the pumps operation?

A: The flexible coupling absorbs minor misalignments between the motor and pump, helping to minimize vibration, reduce mechanical stress, and extend equipment lifespan for continuous and trouble-free operation.

Q: What benefits does the red epoxy coating provide?

A: The standard red epoxy coating protects the external surfaces from corrosion and environmental damage, ensuring longevity and compliance with recognized fire safety equipment standards.
