A superação dos desafios únicos do sistema de águas residuais de Gibraltar, que levou a uma solução eficaz para os problemas de bombeamento que ocorrem, é o mais recente exemplo de sucesso da Vaughan Chopper Pumps. Especialistas em bombeamento de sólidos A P & M PUMPS, distribuidora britânica da Vaughan Chopper Pumps, e a Aquagib, empresa nomeada pelo Governo de Gibraltar, trabalharam em conjunto no projeto para fornecer uma solução de longo prazo. Durante vários anos, houve uma necessidade de manutenção e reparos significativos resultantes de bombas que não lidavam com trapos pesados e sólidos que entravam no sistema de águas residuais.
The problems Aquagib were experiencing were mainly due to the necessity to avoid using submersible pumps because of salt water corrosion. This was due to the fact that pumping stations on Gibraltar utilise sea water available to them for all their waste water flushing systems for both domestic flushing and in the pumping stations.
Initially the answer to the problem was for the pumping stations to utilise a priming system involving a concept developed originally for filling steam engine water tenders with clean water. When used with an open-channel impeller centrifugal pump these systems operated to specification. However, as a result of significant changes in the nature of the solids (being less degradeable) the pumps became increasingly less reliable and prone to blockages within the priming system, causing the pumps and components to fail prematurely. Combined with difficulties in obtaining critical spare parts for the pumps that are now obsolete, the cost of maintaining the pumping stations in Gibraltar was unacceptable. Aquagib’s search for a solution was answered with the help of a Vaughan SP6K chopper pump, which was supplied initially on a trial basis at the Waterport Pumping station. Situated adjacent to the prestigious Ocean Village complex and one of Gibraltar’s high profile pumping stations, the Waterport Pumping facility is on an area of reclaimed land which includes several high value apartment developments overlooking a marina, restaurants, bars and other leisure facilities.
É também na importante rota pedonal do movimentado terminal de cruzeiros para a cidade de Gibraltar. Consequentemente, as frequentes quebras nas bombas resultaram, além dos altos custos de manutenção, dos indesejáveis problemas para uma grande população local, de ruídos, odores e potenciais riscos à saúde, em uma área particularmente sensível.
Following the successful trial of the pump, a standard Vaughan self-priming chopper pump was installed at the Waterport pumping station in October 2007 and has run consistently well with only routine maintenance required. As a result of this consistently reliable operation Aquagib have installed a second pump at the Waterport site. Furthermore, another seven Vaughan Chopper Pumps have since been installed in other pumping stations in Gibraltar, with plans to replace others in the future as well as them being specified for the new pumping stations being planned.
Comentando sobre o sucesso das bombas, Derek Cano, Diretor de Operações da Aquagib, confirmou: “As bombas Vaughan solucionaram uma dificuldade contínua que tivemos durante muitos anos ao lidar com bloqueios de bomba, eles trabalham efetivamente em esgotos não blindados com alto teor de água do mar” . Ele acrescentou: “A P & M Pumps forneceu um excelente suporte que nos permitiu instalar e operar as bombas de forma eficaz”.
Through their experiences at numerous installations, P&M Pumps have been able to demonstrate that Vaughan Chopper Pumps can bring significant cost-savings. In most cases, retrofitting a Vaughan Chopper Pump into a problematic area improves the whole process and will be self-financing, with payback periods of less than one year, thereafter minimising the effect to the budget holders.
