PS450 is a fully submersible pump driven by a permanent magnet type synchronous motor. IDRA has a flow regulator fitted to the front section, which permits precision variation of the water flow. This is the Henri PS450 pump. The PS450 is 4 1/4" high, 4 1/4" wide and 3" in length. Rated at 450 gallons per hour, the PS450 magnetic-drive pump is a submersible, recirculating pump, made for continuous use in all water applications. As with all of our pumps, the PS450 features an epoxy-encapsulated motor and corrosion-resistant housing for long life. UL/CUL approved for safety, its compact design and superior performance make it ideal for decorative fountains, ponds, and water displays, as well as for removing standing water. Energy and cost efficient and 25 foot power cord. U.S. and Canadian UL-approved.
