The client has customers all over the Gulf Cooperation Council (GCC), including municipalities, real estate companies, private developers and facility management companies. They needed to increase the operational efficiency of the sewage collection and drainage stage.
Vacuum pumps are used to convey either sewage or waste material from its source to the collection vessel, commonly known as a sewage collection tank. They are an element of a vacuum sewage system.
The client needed a pump that would adapt to the variable demand in their processes and help them cut down on operational costs and maintenance.
Atlas Copco’s GHS VSD⁺ series is a range of oil-sealed rotary screw vacuum pumps with variable speed drive (VSD) technology. The technical features of the GHS 730 VSD⁺ allowed the pump to deliver only what was required, limiting the number of starts and stops and consuming less energy.
According to Atlas, the speed drive and inbuilt control system of the vacuum pump automatically adjusts the speed of the pump as per the demand, helping to boost energy savings by almost 26%. This enabled the overall vacuum sewer system to achieve higher efficiency without unnecessary energy wastage.
Atlas replaced 3 oil-sealed rotary vane vacuum pumps, which consumed 45 KW of energy. The Atlas Copco GHS 730 VSD⁺ is said to consume 33 KW in comparison.
The GHS 730 VSD⁺ has an inbuilt monitoring system – the Elektronikon. It offers status updates and enables the pump to be operated remotely for better control and constant monitoring.
