Balboa HA440NG 2-Speed 1.5HP Hot Tub Spa Pump – PW-HA443
The Balboa HA440NG is a high-performance, dual-speed massage pump designed for spa and hot tub systems. Manufactured by HydroAir — a division of Balboa Water Group — this 1.5HP pump delivers outstanding hydraulic performance that matches or exceeds the output of the older 2HP HA440 Magnaflow model it replaces. Whether you’re running powerful massage jets on high speed or keeping energy costs down during filtration cycles on low speed, the HA440NG handles both with ease.
Built around a Totally Enclosed Fan Cooled (TEFC) motor with an IPX5 water-resistance rating, this pump is engineered to withstand the demanding conditions of spa environments. The center suction wet end with radial side discharge ensures efficient water flow, and carbon ceramic seals with Viton® elastomers provide long-lasting resistance to heat and chemical exposure. VDE-approved to European standards EN60335-1 and EN60335-2-41, this pump meets the highest safety benchmarks.
Supplied complete with a 4-core cable and AMP plug, the HA440NG is a like-for-like direct replacement for the discontinued ITT HydroAir Magnaflow HA440 and is frequently found as OEM fitment in Spaform hot tubs. Its compact 48-frame design also makes it ideal for installations where cabinet space is limited.
