Our Hurricane Pump is ideal for a heavy duty waterfall or filter system, as it has the necessary power to force large quantities of water through long or high pipe runs, or through restrictive UVC''s and filters. It are designed for continuous operation, even in the harshest pond environments. The pump features an oil-free magnetic-driven, epoxy-protected ceramic shaft and a ceramic impeller for long life. This reliable and quiet underwater pump will give you a cost-saving, energy-efficient operation.
