Dowdens Pumping and Water Treatment successfully designed, manufactured and commissioned a diesel fire pump system for Sedgman Limited operating the Red Mountain Operation – Millennium Coal Mine.

Traditionally fire pumps are only required to either sit idle in the basement of high rise buildings until the event of a fire where they are run until they self-destruct, or used on mine sites more frequently and for long hours during power outages and for onsite pressure boosting.

The Problem

Here at Dowdens Pumping & Water Treatment we pride ourselves on supplying our customers with systems designed for longevity and continued onsite use. Often this means more money is spent on the build initially but this investment is quickly and easily recouped via lower ongoing maintenance and repair costs.

This particular diesel fire pump system utilised a large diesel-driven industrial standard pump capable of operating at slower speeds meeting a duty of 45 L / sec @ 80 m head.

Our Solution

The pump and diesel engine were upsized compared to the existing system, ensuring long term problem-free operation. All fabrication, assembly and performance testing conducted by Dowdens Pumping & Water Treatment in Mackay guaranteeing product quality. The controller used is a digital Welling & Crossley Controller which has been successfully used by Dowdens in other fire pump projects.
