Grundfos has long been regarded for their high quality and reliable pumps. The Grundfos SCALA2 takes design innovation, comfort and simplicity to the next level and is set to be a game changer in domestic boosting. The NEW Grundfos SCALA2 is a robust, fully integrated, self-priming pump suitable for use from both above and below ground water sources. The compact system features a pump, motor, tank, sensor, drive and non-return valve in one compact unit that is quick and easy to install.
The SCALA2 is an energy efficient pump featuring an integrated speed controller that ensures constant water pressure regardless of variations in demand or inlet pressure. For those living in areas of poor power supply or those that are sometime affected by power outages, the SCALA2 can also be run on a generator, due to its ability to be able to handle varying voltages.
The variable speed controller also matches the power consumption with the required water output, which also helps to conserve energy and reduce your energy bills. To protect the pump and help ensure a long life, the SCALA2 includes a range of protective features. Dry run protection automatically stops operation when the water source runs out, to help prevent damage, and the anti-cycling feature detects any unnatural cycling and alerts the user via the protection indicator on the control panel.
Another unique benefit of the SCALA2 is its quiet operation, thanks to the permanent magnet motor and water cooling technology. The high efficiency motor is significantly quieter than traditional speed-controlled motors and the SCALA2 is cooled by the water it pumps, eliminating the need for a noisy fan. This makes the SCALA2 one of the quietest domestic boosting pumps currently available on the market.
For ease of selection, the SCALA2 suits most domestic pressure boosting applications and is capable of supplying water for small single level homes up to larger multi-storey homes.
Dowdens Pumping & Water Treatment are proud to be promoting the very latest innovations and energy savings available via our professionally engineered solar pumping systems for the farm or homestead.
Appleton Pastoral Company (a Queensland Beef Cattle Enterprise with several properties across Central Queensland) purchased a solar pumping system to manage their onsite stock water reserves.
The system was required to pump from Appleton Pastoral Company's new dam to a turkeys nest holding dam (geographically located at the top of a major elevated ridge in Alpha).
The system pumps on average 100,000L / day @ 20m total head. From the turkeys nest the stock water then gravity feeds several kilometres down the elevated ridge to troughs and other water tanks located throughout the property.

Examples of Dowdens Water and Sewage Treatment projects:
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.CLICK IMAGES TO VIEW FULL PROJECT GALLERY
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.
Key Project Features:
Downer EDI Mining [a division of Downer EDI Limited] has engaged Dowdens Pumping & Water Treatment [Brisbane] to design, manufacture, install and commission a Heavy Vehicle Wash Bay and associated plant treatment equipment at the Meandu Coal Mine located in Tarong, South East Queensland.
Since January 2013 Downer EDI Mining has been providing mining services at Meandu Mine as part of their long-term rolling contract with TEC Coal Pty Ltd, a wholly owned subsidiary of Stanwell Corporation Limited. Downer provides a total mine service to TEC Coal, including mine management, planning, drilling, overburden removal (including dragline and truck-and-shovel operations), coal mining, coal processing, rehabilitation, and maintenance of mobile and fixed plant.
Downer EDI's Heavy Vehicle Wash Bay project tender was won primarily due to Dowdens ability to expertly design / manufacture / install and commission specialised equipment, built in-house & onsite to meet our specific client's unique requirements. With a history of successful installations over the past 15 years within the Queensland Mining Sector, Dowdens is Queensland's premier pumping & water treatment organisation.
Downer's project brief to Dowdens Brisbane was for the design / manufacture / installation and commissioning of a Heavy Vehicle Wash Bay capable of processing a minimum of 5 vehicles per day, with each vehicle taking approximately 1 hour to wash. Meandu Mine required this new Heavy Vehicle Wash Bay to be constructed after the mine had recently purchased a fleet of new generation trucks (KOMATSU 830E Trucks) which are considerably larger in size compared to their existing fleet.
To ensure Meandu Mine continued to meet their Environmental Discharge requirements Dowdens designed and incorporated 4x Settling Pits & 3x Oily Water Separators into the construction of the Heavy Vehicle Wash Bay. In Queensland it is a legal requirement for mine sites to treat (separate) any sludge or oil from any waste water coming from a Heavy Vehicle Wash Bay.
Pictured below you can see the 4x large Settling Pits (empty) that are used to catch / store (via gravity feed) waste water from the Wash Pad area. The waste water generally contains some grease, oil, coal fine and soil (mud). The coal fine, mud and other solid particles washed off the trucks is allowed to settle to the bottom of the Settling Pits - the pits are then intermittently emptied by a Bobcat excavator.
The waste water (still containing grease and oil) is pumped from the Settling Pits via progressive cavity pumps into 3 individual 'Oily Water Separators' to remove the remaining contaminants. Once the waste water has been through this treatment stage it is pumped back into Meandu Mine's network of onsite holding dams to be used in other site extraction and processing applications.
Dowdens design philosophy for this project was: Cost Effectiveness - Current Best Practice - Ease of Installation - Simple Plant Operation - Plant Reliability & Reduced Maintenance.
Key Project System Components are listed below (click for component specs):
Dowdens Pumping & Water Treatment have successfully designed, installed and commissioned a specialised Ultraviolet filtration system for the Queensland Health Mackay Renal Unit.
Project Requirements: The original system operated by pumping town water to individual filtering stations where the water would pass through a 5 micron, 1 micron and carbon filter on its way to the dialysis machine (which has an internal reverse osmosis filter).
The issue Dowdens faced was the original system filters were only lasting between 5 - 15 hours, and by this stage they were black and needed to be replaced!
After reviewing detailed water test results, Dowdens designed a compact, reliable system where the existing pump was upgraded, a water softening unit was added to remove iron, calcium and manganese. Large cartridge filters were also installed to pre-filter the water before it entered a dedicated UV steriliser.
Using the above system the Mackay Renal Unit now only needs to replace the systems filters every 7 to 10 days - saving thousands of dollars in ongoing system maintenance costs!
