Whatever system of water delivery is used, it is crucial that adequate screening is provided to protect the pump and system. Conventional water pump screen filters offer relatively low performance against the ingress of debris and air which may cause excessive wear to the pump. Air and cavitation are the two things that dramatically affect pump performance and longevity. Air induced into a pump will interfere with the hydraulic action and significantly decrease its efficiency, requiring it to operate for longer periods at an increased temperature, thereby consuming more power and decreasing the life of the pump. The Seradisc[1] variable screen filter has been specifically developed by Water Powered Technologies Ltd[2] of BudeW, Cornwall, for the protection of water pumps from cavitation and the ingress of potentially damaging particulates.
About the Seradisc
The Seradisc filter includes 16 discs as standard which will screen particulates of around 4mm and above. Screening of smaller particulates is achieved by installing additional discs (available separately) onto the assembly. The maximum number of discs that should be installed using one unit is 42. This will provide particulate screening of approximately 0.1mm and above.
Construction
Performance
By configuring a number of filters in series, the flow rate will remain the same as for one filter. However, the benefit is that the cleaning interval is increased.
Particulate sizes are calculated. Due to the flexible nature of the discs, Seradisc filters fitted with lower numbers of discs may allow ingress of particulates slightly larger than as indicated on the graph.
