Super duplex pump

The Port Klang Power Station in Malaysia routinely faced “unacceptable” costs associated with downtime on their existing pumps. The pumps required to be taken out of service every six months for the casing to be re-lined with a protective coating to combat the ravages of
chlorine corrosion from seawater. The customer (Tenaga Nasional Berhad) demanded an alternative replacement pump system that could handle the job. The new solution would have to minimise costs and disturbance, whilst matching the existing configuration of pipework and driver. Before offering a solution, Weir’s analysed samples of the pumped fluid to establish the basis upon which to progress. A highly resistant pump was constructed with super duplex stainless steel zeron 100 for long-term savings and cost-effective life. Weir claims the customer can now save 12 days downtime each year, per pump, without loss of pump performance.
