Direct Diesel Driven FW w/Eureka BB2 Pump – System Description

System Description
The fire water pump system is a fully mechanical driven self contained pump system designed according to NFPA20. The diesel engine is connected to the pump with a flexible cardan shaft on a common base frame. All necessary auxiliary equipment will be provided on or near the skid. The cooling method is seawater taken from pump discharge and the complete system is independent of external cooling water

The fully mechanical drive makes this system a very power efficient, light weight and compact solution. The mechanical design results in less fail modes with minimum package control.

There are very few interface points from the system to the user system due to common skid for both pump and driver. Start up of the system is relatively straight forward due to low inertia with no need for excess power. This system is suitable for zone 2 requirement due to limited electric components and instrumentation.

The combination of high power efficiency, the low inertia during start up often result in a smaller driver size compared to electric and hydraulic driver design. The benefit is cost, weight and space savings.

Eureka BB2 pump Arrangement
the EUREKA BB2 pump is a single stage, double suction, horizontal version in compliance with the latest edition of API 610. In general the pump materials comply with the grades listed in API610 and NORSOK M630/M650. The standard materials are 25% Cr super duplex (API610 D2) for seawater applications.
