Pumps with Vortex Impeller

Discharge Bore(mm) 50
Motor Output(kW) 0.15 ・ 0.4

The NHPU-series is a compact, lightweight submersible resin-made pump designed for a variety of applications. They are primarily used for circulating water in koi ponds, aquaculture facilities, and water features like waterfalls in garden settings, making them ideal for horticultural purposes. Since they use food-grade liquid paraffin as lubricating oil, the pumps are safe and fish-friendly.
In addition, NHPU pumps can be used in industrial settings, such as factories, as well as in small-scale wastewater treatment facilities. The pumps are made of resin and 316L stainless steel shaft, which delivers excellent corrosion resistance.
Moreover, they can be easily installed in tight spaces including inside of septic tanks, small-sized wastewater treatment plants and kitchen wastewater traps in homes and office buildings.
