PROLINE HIGH-FLOW SUBMERSIBLE WATER PUMPS are our latest line of Water Pumps by Danner Manufacturing. They each feature a vortex impeller for increased torque flow which eliminates clogging and binding made of F.R.P (fiberglass reinforced plastic) for minimal abrasive wear. The HFS pumps also feature a rugged, durable stainless steel motor which is corrosion resistant for all kinds of weather elements. The HFS Pumps have built-in thermal protection which is a self-resetting automatic protection against overload and overheat conditions. They also feature high-quality double silicone carbide mechanical seals (impeller side) for increased performance and additional abrasive resistance. Great for Ponds, Fountains, Fish-Farming, Landscapes, Irrigation, Water Gardening, Aquaculture (Water Circulation), Agricultural, Streams, Cascades, Waterfalls, Water Transfer, Recirculation and Water Drainage.
