The Waterway Hi-Flo pumps are designed especially for hot tubs and spas. Offering a larger diameter wet end the higher volume of water these pumps push through makes the 60% more efficient than the centre discharge models.
Hi-performance Waterway wet ends are driven by quality E.M.G motors that by design, dissipate heat quicker and give lower running temperatures. Two speed E.M.G motors also benefit from split start and run capacitors to make them more energy efficient.
The compact 48 frame pumps allow for installations into tight spots or in spa cabinets where space is limited and a larger 56 frame pump simply won't fit.
Waterway pumps are great alternatives to more expensive brands as well. Their wet end shape and dimensions mean they can replace most hot tub pumps out there from the likes of Aqua-flo, Century Laser, AO Smith, Vico, Sta-Rite, Emerson just to name a few. Usually little or no modifications are required.
An ideal pump to replace the discontinued HydroAir Magnaflow HA440 two speed pumps 40-44092V2.
The Hi-Flo pumps are supplied without a cable. We recommend re-using the cable from your old pump to ensure correct fitment to your spa pack.
