Overview
- The Small Mouth Series Variable-Frequency Water Pump is designed for demanding circulation applications such as garden koi ponds, large aquariums, seafood tanks, hydroponic systems, and garden sprinklers. Six models are available, with maximum flow rates from 5.5 to 7 m³/h and maximum lift heights from 9 to 13 m.
- The range includes fixed-power HRD-75, HRD-100, and HRD-120 models, as well as adjustable-power HRD-75A, HRD-100A, and HRD-120A models. Adjustable models combine variable-speed operation with an external controller, allowing the output to be matched to different circulation requirements. The variable-frequency motor provides stable power output while supporting low-noise and energy-efficient operation.
- A pure copper motor and corrosion-resistant ceramic shaft support efficient, durable performance in freshwater and seawater environments. The resin-sealed body provides electrical insulation, while integrated overheat protection helps protect the pump during operation. A 3.5 m power cord provides additional installation flexibility.
