This powerful pond pump can create a large waterfall (maximum head 4.5 metres) or power a filter system for a pond up to 32,000 litres. It can handle solids up to 10mm and comes with a 5 year guarantee. New improved version - Laguna pumps now feature a new generation of motor design with SPT (Smart Pump Technology). This is an integrated self-regulating system that continually monitors the pumps performance, impeller direction, hydraulics and force. The result of this is improved performance and better economy.
