Description
Balboa 1 HP Olympian Replacement High-Efficiency Bath Pump — 115V, 9A (Model 97411-420)
If you’re upgrading an aging hot tub or whirlpool, this Balboa Water Group replacement pump delivers a true performance upgrade without overhauling your entire system. Designed as the replacement for the original Olympian Mark II/III pumps (which are no longer manufactured), this unit combines the reliability Balboa is known for with a next‑generation, energy‑efficient design.
The standout feature is the new volute design that yields higher water flow per amp. In practical terms, you can expect robust jet performance while running on a lower amperage motor, which translates to measurable savings on operating costs and cooler electrical consumption in the long run. Balboa calls this improvement Equivalent Pump Performance (EPP), a clear signal that you’re getting more pump for each watt of power used.
Designed for fit, optimized for performance
Key installation and design details help this pump fit where older units did:
- 5 inches wide by 6 inches deep, making it a straightforward swap in many standard tubs with restricted back jets or compact footprints.
- 115V, 9A, 1 HP: Solid, reliable power and flow to keep your spa experience moving—without unnecessary amperage draw.
- Glass-reinforced composite housing: A durable, lightweight build that resists corrosion and fits tight spaces.
- Self-draining suction inlet: Helps reduce winterization effort and minimizes residue buildup when the tub is not in use.
- Quiet operation: Designed to minimize noise, preserving the tranquil ambience of your spa environment.
- UL Recognized (USA & Canada): Peace of mind that this pump meets recognized safety standards across North America.
Why choose this Balboa HE pump over older or generic replacements?
It’s not just about swapping parts—it’s about achieving better performance with fewer compromises. The high-efficiency design means you can:
- Move to a lower amp requirement while meeting or surpassing your existing jet load, which can reduce electrical strain on your system.
- Increase jet count or maintain current jet intensity without needing a more powerful or louder pump.
- Benefit from a compact, modernized housing that maintains reliability while easing installation in tubs with limited space.
Ideal use cases
This pump is perfect for:
- Replacing obsolete Olympian Mark II/III pumps in hot tubs or whirlpool baths where the original unit is discontinued.
- Upgrading to a higher-efficiency solution that reduces energy usage while preserving or enhancing jet performance.
- Installations in tubs with back jets or garden tubs that require a compact, lightweight pump with strong water flow.
What to expect in real-world service
Users typically notice a steadier, quieter flow with less energy draw, thanks to the EPP-design pumps’ efficient water delivery. The durable glass-reinforced housing stands up to regular spa use, while the self-draining inlet simplifies maintenance and seasonal prep. As part of Balboa’s trusted product line, you gain access to a broad ecosystem of compatible controls, jets, and accessory components should you plan future upgrades.
