Heavy Duty Diesel Fire Pump System

Case Study

Customer: Sedgman Limited - Red Mountain Operation

Location: Millennium Coal Mine - 160km SW of Mackay

Specifications & Features:

Dowdens Pumping and Water Treatment have 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.

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 outlaid 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 45L / sec @ 80m head.

Project's Supply Scope:

  • 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

Broad Acre Irrigation Project

Case Study

Customer: Wilmar Sugar Australia Limited

Location: Gibson Creek, QLD

Specifications & Features:

Wilmar Sugar Australia Limited employed Dowdens Pumping & Water Treatment [Mackay] to deliver a broad acre irrigation system at their Gibson Creek sugarcane farm. Wilmar Sugar Australia Limited is Australia's largest raw sugar producer and one of the top 10 producers in the world.

The Gibson Creek sugarcane farm has a total area of 2,000ha, with works completed by Dowdens to date delivering irrigation to over 750ha of sugarcane - this project is still ongoing with the aim to irrigate the full 2,000ha upon completion. The broad acre irrigation system was designed, sourced, installed and commissioned by the Dowdens Pumping & Water Treatment Agricultural Sales Team, which has over 125 years combined agriculture irrigation experience.

The system is required to pump water stored in Wilmar's onsite dam (which when completed will hold a total of 2,000ML) to various irrigation devices watering 2,000ha of sugarcane.

To date the project has seen the team at Dowdens construct, install and commission six Valley Center Pivot Irrigators, with spans ranging from 520m down to 410m, and three hard hose poly line traveling irrigators.

Water for the irrigation system (sourced from Wilmar's 2,000ML onsite dam) required Dowdens to lay an extensive network of poly and PVC mains pipework ranging from 500mm to 150mm in diameter. In total over 12kms of mains pipe has been laid so far.

The entire system is gravity fed from the large onsite dam with a 6-cylinder John Deere diesel engine centrifugal pump feeding the six pivots, and three IVECO-Caprari multistage diesel booster pumps [pictured below] kicking in to raise mains pressure when water is required at the three hard hose poly line travelling irrigators.

The entire project was overseen and managed by Glenn Agnew from the Dowdens Pumping & Water Treatment [Mackay] Agricultural Sales Team.
