Fire Pump

Grundfos - Fire Systems

fire-pump-grundfosOverview fire systems by Grundfos pump

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 base frame.

Electric pump types can be ordered 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 Pump

The pump materials are in compliance with EN 12845 and prEN12259-12:

  • 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 Pump

Grundfos offers a complete, factory-assembled controller in a steel plate cabinet, suitable for wall mounting or to install free-standing. The controller pump complies with the EN 12845 standard. The controller for diesel-powered pump is always mounted on the base frame.

Electric motor

The electric motor is an MG or MMG motor complying with local standards for electric motors. As from 16 July 2011, the motors used in Europe will be IE2 = EFF 1 motors.

Diesel engine

The diesel engine can operate continuously at full load at site elevation with rated output in accordance with ISO 3046-1:1986. The pump reaches full operational speed within 15 seconds; the engine is capable of starting at a room temperature of 5 °C.

Each complete engine pump unit is tested on the manufacturer’s test bed for at least 1.5 hours at rated flow rate, and the result recorded on the test certificate.

Applications Pump

The Grundfos fire pump units are typically used in fire-fighting applications for supplying water to fire-hose reels, fire hydrants or sprinkler systems.

EVMU, EVMUL, EVMUG Series - Ebara Pumps

Stainless Steel Vertical Multistage Pumps

EVMU, EVMUL, EVMUG Pumps Series

With initial hydraulic coverage to 100 GPM and 800 feet TDH, the EBARA Pumps model EVMU is designed for booster, water purification, and hot water applications pumps.

State-of-the-art formed stainless steel and several proprietary internal components make the EBARA pumps model EVMU superior to existing designs. The EVMU material is between 50 to 100% thicker than all current similar product offerings, for a true industrial design with cast stainless steel pumps flanges for maximum installation support.

EVMU 32, 45 and 64 models consist of cast iron or 304SS hydraulic assemblies. Different mechanical seal face options are available for the three models and incorporate a separate thrust bearing in lieu of motor bearings, a popular design feature.

Models EVMU3-18, EVMUL 3-64 pumps series are NSF/ANSI 61 Annex G listed
