Balboa 1.0 HP Pump Impeller Assembly (17400-0120)

The Balboa 1.0 HP Pump Impeller Assembly (17400-0120) is a genuine Balboa Water Group replacement impeller assembly built to restore correct hydraulic performance in compatible spa and bath pump systems. Impellers do the real work inside the wet end by translating motor horsepower into water movement, pressure, and jet action, so even minor wear can have a noticeable effect on circulation, therapy strength, and overall equipment efficiency. When a spa pump sounds normal but flow has weakened, the impeller is often one of the first assemblys worth replacing.

Balboa has remained one of the most influential manufacturers in the industry because their pump components are engineered for fit, balance, and dependable long-term operation. That matters with impellers, where proper blade shape, hub fit, and dimensional accuracy directly affect water output. A correctly matched Balboa impeller helps maintain the performance profile the pump was designed to deliver instead of forcing the motor to work harder against inefficient internal conditions.

This impeller is intended for service work where restoring circulation, pressure, and pump efficiency is more cost-effective than replacing the entire assembly. It is especially valuable in repair situations involving reduced jet performance, worn internal pump parts, or system output that has dropped off over time. Replacing a damaged or rounded impeller can also help reduce strain on associated pump components and support smoother overall operation.

Because Balboa equipment is so widely used by manufacturers and service companies, genuine OEM replacement parts continue to outperform guesswork substitutes in real-world reliability. For higher-value spa equipment, the difference between a generic internal component and a correct-fit Balboa part can affect both installation quality and long-term durability.

For spa owners and technicians alike, this replacement helps protect the value of the full system while restoring the kind of dependable performance customers expect from the Balboa name.
