Allied Pumps’ variable speed pressure system varies the speed of one or more pumps to produce a constant, non-pulsating pressure supply that responds to changes in demand. A dedicated process controller works with a digital frequency converter and pressure transducer to control the lead pump and bring additional pumps online as required.
The packaged systems can incorporate single or multiple pumps together with pressure tanks, valves, gauges, pressure & flow monitoring equipment, and filtration or treatment options. Components are mounted on a common frame with interconnecting pipework and manifolds terminating in single suction and discharge points for straightforward site connection.
The City of Subiaco had an initiative to improve water quality. The focus was on reducing pollutants in Lake Mabel Talbot. The lake is in the conservation category wetland under the Environment Protection policy and functions as a Water Corporation compensating basin. The lake collects rainfall runoff from four sub-catchments, totaling 300 ha. A Gross Pollutant Trap needed to treat the entire flow prior to entering the system, and our Baffle Box was the only system to appropriately meet the design criteria. The Baffle Box was able to catch leaves and other pollutants before they could enter the lake. The result of this project was cleaner water and an improvement in the water quality.
The Christmas Island International Airport serves visitors and residents of Christmas Island, a territory of Australia in the Indian Ocean. The building required a containerised system for its fire pump set. We were able to offer expert advice and help in the installation and usage of the system for the Christmas Island Airport personnel.
It’s been 25 years, and the Bickley Booster Pump Station is still going strong. In 1992, we took on this project. This challenge began with the need to solve a low-pressure problem in the Orange Grove area. A dual pump system operating on a variable speed control was installed. This included the base, pipework, valves, control system and pressure vessel. The pump set is still functioning correctly and addressing the original issue. This project represents the quality and endurance of our pump systems.
The Craft Street project involved 8 adjoining lots which required fire protection. To solve this problem, two (2) tanks measuring 5.12 m in diameter by 9.20 m high were assembled onsite and situated next to a fire pumpset in its own custom built enclosure. By collaborating, the owners of the 8 lots were able to share the costs and find a collective solution that worked for them. The short lead time was met and we were able to meet the client expectations in the provided timeframe.
Blockages occur fairly regularly at Graylands Hospital, Western Australia’s largest mental health facility. Objects and clothing were often being introduced into the plumbing system. With 1,053 fixtures, the system needed help breaking up these foreign objects. Two of their grinder pumps were not properly handling foreign objects. After much investigation, the most practical option was to install a channel grinder in the existing mechanical screening pit. We designed specialised guiderails from 316 stainless steel. They were built in-house to suit the existing concrete structure. This solved the issue and eliminated peak flow blockages. The system has now been up and running for 24 months with no issues.
Eastern Goldfields Regional Prison is an Australian prison located in Boulder, Western Australia, and opened in 1980. An upgrade to the fire pump skid and commissioning was necessary in 2014. The primary challenge was carrying out both tasks at the same time including upgrading and commissioning. We worked hard to balance both tasks resulting in a successful delivery of the project.
Canal Rocks Beachfront Resort sits waterfront at Smiths Beach in Yallingup. It offers beautiful accommodation for families, friends and couples visiting Yallingup and its surroundings. The facility required a fire pro pump set. We used the first AS2941-2013, which we designed, manufactured and installed the system, ensuring it met all standards and regulations. The project had its challenges since it was a first, however its successful completion enabled us to learn valuable information which will help in future installations. The project highlighted our ability to quickly learn on the job whilst successfully completing the project brief.
The Cockburn Central Police Station required several tank and pump solutions. Initially a galvanised regular tank was recommended. However, there were design issues with the concrete slab. The station requested an in-situ concrete tank liner. The design was changed to meet this need. Allied Pumps was able to provide a turnkey solution for our client on this project, saving the client from having to engage the services of several different sub-contractors to work on various aspects of the tank installation. This enable the client to place a single order with us for all the work on the tank and supply of the pumping systems, enabling him to focus on other aspects of the project. The final project consisted of a panel tank, circulating pump pack, hot water circulator, fire pump and tank liner pack. The result was a seamless integration between the pumps and the tanks, and reliable fire protection has been the overall outcome.
Located on the Burswood Peninsula, the Optus Stadium is part of a large redevelopment that has become a draw card to thousands of people. However, as with all new developments there was a significant change to the existing landscape. Part of the Optus Stadium is bounded by the Swan River and river traffic, some of the retaining walls and steel piles on the water’s edge which could be seen from the water and needed to be addressed which could not be achieved using a land based planting scheme or additional construction. Allied Pumps created an environmentally sound and sustainable floating treatment wetland that can be configured in rafts of endless configurations. They can fit any existing space or water body shape and can operate in fluctuating water levels which was an essential requirement for this project. While the floating treatment wetlands are primarily a water treatment tool, they have the added bonus of being visually appealing with the use of wetland sedges, rushes and grasses providing fast and easy to install beautification options.
The Roy Hill railway is a 344km standard gauge, single line, heavy haul railway built to transport 55Mtpa of iron ore from the Roy Hill Mine to the Port stockyard facility, in the Boodarie Industrial Estate south of Port Hedland. This operation uses a lot of diesel and was in need of a large bulk diesel facility to rapidly fuel the trains to meet production and delivery demands. This would allow them to function more efficiently. Nothing of this nature had ever been accomplished. Traditionally fuel facilities have pumps for unloading, loading and other refuelling activities located around the site and are wired back to a Motor Control Centre building. Our solution was to consolidate the pumping, compressed air equipment and Motor Control Centre onto a single super skid. The skid was pre-fabricated, assembled and tested at our facility and lifted into place on site where only a single lift was required. The project was delivered on time and as requested.
A pressure transducer provides system pressure feedback to a dedicated process controller. The controller works with a digital frequency converter to vary the lead pump speed and bring additional pumps into operation in response to changing demand.
Allied Pumps’ variable speed pressure system provides improved hydraulic efficiency, lower power consumption, reduced pump cycling, and accurate tracking of system demand.
Yes, Allied Pumps’ variable speed pressure systems can incorporate single or multiple pump units. The variable speed controls can vary the lead pump speed and bring additional pumps online according to the signal from the pressure transducer.
Yes, Allied Pumps’ variable speed pressure system can incorporate sediment filters, UV filters, and water softeners for when water quality needs improvement.
Yes, available variable speed features include remote status and fault monitoring, as well as friction loss compensation and multiple setpoint selection.
