DESCRIPTION & SPECIFICATIONS :

A Wet Fire Sprinkler System is the most reliable and simple Fire Sprinkler System. The piping network of a Wet Fire Sprinkler System contains water that is under pressure. When anyone of sprinkler heads in the system is set off, water will start flowing and the fire sprinkler system will begin to extinguish the fire. Wet riser system comprises duty fire pumps with standby pump discharging into riser pipe with landing valves at each level and to jet at the fire. A jockey pump is usually provided to maintain system pressure. The Wet Fire Sprinkler System can be installed in retail locations, warehouse spaces, manufacturing facilities, office spaces, and apartment buildings.

Overview

A NBF is an end-suction pump made for fire sprinkler pump applications. NBF is a close-coupled type and NKF is a long-coupled type.

The NKF fire system is an NBF or NKF end-suction pump integrated with a coupling and a driver, which may be an electric motor or a diesel engine, assembled on a suitable base frame.

Electric pump types are available as a COMPACT model (inclusive of a controller integrated onto the baseframe).

Diesel-driven NKF. A controller always forms a part of the system.

Materials

The pump materials are in compliance with the norms:

• Impeller and wear rings are made of bronze
• Wet parts such as shaft, washers and nuts are made of stainless steel
• Castings are made of cast iron.

Controller

Tatsam offers a complete, factory-assembled controller in a steel plate cabinet, suitable for wall mounting or to install free-standing. The controller complies with the norms. The controller for diesel-powered pumps is always mounted on the base frame.

Electric motor

The electric motor is an MG or MMG motor complying with norms for electric motors.

Diesel engine

The diesel engine can operate continuously at full load at site elevation with rated output in accordance with the norms. The pump reaches full operational speed within 15-20 seconds; the engine is capable of starting at a room temperature of 15 °C.
