Description
Balboa.5 HP Pump Impeller for WOW/Ultima (Green Stripe) – 1212058
If your Balboa spa pump from the WOW or Ultima line isn’t delivering the flow it should, the Balboa.5 HP Pump Impeller (Green Stripe), part number 1212058, is the OEM solution designed to restore proper performance. This impeller is a genuine Balboa Water Group component that replaces older identifiers 5190-050 and 606349, ensuring compatibility with the 0.5 HP WOW/Ultima pumps that use the green stripe configuration.
Why this impeller matters
Over time, pump impellers wear, deform, or crack, reducing water flow, increasing motor load, and causing uneven heating or jet pressure in your spa. Replacing the impeller with the correct 0.5 HP WOW/Ultima unit helps:
- Restore optimal water circulation for even heater performance and improved jet reach
- Reduce motor strain and save energy by maintaining accurate pump head pressure
- Eliminate cavitation noises and inconsistent spa water flow
- Maintain the original design intent of your Balboa WOW/Ultima system
Who should consider this part
- Owners of Balboa WOW/Ultima spa pumps with a 0.5 HP motor seeking a genuine OEM replacement
- Technicians conducting routine pump maintenance on Balboa hot tubs or spas that require part 1212058
- Owners facing reduced flow, pulsating jets, or fluctuating heater performance due to worn impeller blades
Key details and compatibility
- Official Balboa Water Group replacement impeller for 0.5 HP WOW/Ultima pumps with the green stripe designation
- Manufacturer: Balboa Water Group; Balboa part number 1212058
- Replaces older part numbers: 5190-050 and 606349
- Note: This component is listed as discontinued by the manufacturer, so availability may be limited and substitution timelines vary
Practical installation and care tips
- Power off at the breaker before starting any pump work. Ensure the spa is fully de-energized and water is cooled if applicable.
- Access the pump housing and remove the old impeller following your Balboa WOW/Ultima service manual instructions.
- Inspect the pump shaft and housing for wear or debris; clean any buildup to prevent misalignment or new impeller damage.
- Install the 1212058 impeller with the correct orientation so the impeller blades engage the drive shaft and pump volute properly.
- Lubricate o-rings lightly with a compatible silicone lubricant and reseal the housing to prevent leaks.
- Test the system: restore power, run the pump, and verify smooth operation, consistent flow, and no unusual noise before returning the spa to normal use.
Practical considerations and alternatives
Because this part is discontinued by Balboa, it may be challenging to source in the future. If you can’t find a new 1212058, consider working with a qualified service technician to explore compatible OEM alternatives or sourced replacements that preserve the original pump’s performance characteristics. When replacing, prioritize parts that match the green stripe configuration and the 0.5 HP WOW/Ultima specification to maintain pressure, flow, and heater efficiency.
Use cases and outcomes
Ideal for spa owners rebuilding a Balboa WOW/Ultima 0.5 HP pump where the impeller has worn blades, reduced impeller diameter, or signs of cavitation. Expect restored jet strength, steadier water temperature regulation, and quieter operation once the proper impeller is in place. This part helps you extend the life of your spa’s circulation system while preserving the original design intent of your Balboa equipment.
Why choose this Balboa impeller
Choosing the OEM impeller—when available—ensures precise blade geometry, correct gearing with the drive shaft, and compatibility with the Balboa control and heater systems. For WOW/Ultima users with a 0.5 HP configuration and a green stripe setup, 1212058 is the aligned choice that supports reliable circulation and optimal spa performance.
