Longwall Boost Pump Station

Case Study

Customer: Anglo American - Australia

Location: Moranbah North Coal Mine - Moranbah, QLD

Specifications & Features:

Dowdens Pumping and Water Treatment was engaged by Anglo American Moranbah North Coal Mine to design, engineer and build a boost pump station to supply raw water to the longwall area.

Dowdens Pumping and Water Treatment designed and built the longwall boost pump station utilising dual variable speed pumps to enable the station to cater for varying duties as the underground workings progress further away from the station.

Anglo American's Moranbah North coal mine began operation in 1998 and currently supplies 4.5m tonne annually of high fluidity premium hard coking coal mainly for export to iron and steel manufacturers in Japan, Korea and Taiwan.


The pump station boosts water pressure to the longwall currently some 6,000m away.

Comprehensive 'pre-challenge' testing was completed prior to the station being transported to site, with all parameters being set during this time.

Dowdens team of specialised engineers, CAD draftsmen and tradespeople were able to design and build the station on time and to a tight budget, with Anglo American extremely happy with the work undertaken and product supplied.

Testimonial: Anglo American - Australia (Moranbah North Coal Mine) reported "The longwall booster pump station was taken underground into immediate service after only a couple of days. There is normally a one or two month delay with above ground commissioning for all new units. Since the pump powered up after the first run it has not stopped running and is sitting at only 10% duty. The longwall has cut 128,000 tonnes so far which is exceptional. Any future boost pump orders from Dowdens Pumping and Water Treatment will not require any changes to the design or manufacture."

Key Pump Station Features:

  • KROHNE flow meter
  • Pump station utilises four pressure transducers to feed real time pumping data to the computer control
  • Two vertical stage pumps directly coupled to two 45kW motors
  • As the booster pump station was dealing with high pressures all piping and flanges have a 3,000kPa rating
  • Pump station fitted with QDS (Quick Detachment System) lift points - allowing the station to be transferable via the underground Line Eimco
  • Touch screen interface enables underground miners access to real time amperage, bearing temperature and flow rate data
  • The unit operates via a PLC (Programmable Logic Controller) and SCADA (Supervisory Control and Data Acquisition) system meaning it can be remotely operated from the mine control room on the surface, or underground via the unit's electronic controls

Total Water Volume Transfer: 30L/sec @ 80m head (currently)

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
