Balboa Ultimax 5235208-S 2-Speed Spa Pump – 230V, 56-Frame, 8.8/3.0A

Replace your aging spa pump with the Balboa Ultimax 5235208-S, a 230V, 56-frame pump rated at 8.8 amps on high speed and 3.0 amps on low speed. This complete motor-and-wet-end assembly features center suction and side discharge with nominal 2-inch plumbing connections.

The pump can be wired for one-speed or two-speed operation, depending on your spa control system and installation requirements. In a compatible two-speed installation, low speed provides circulation and filtration, while high speed powers the therapy jets.

Power cord and pump unions are not included.

Specifications

Older Balboa and Vico Pump Cross-References

Spa-parts suppliers cross-reference the 5235208-S Ultimax pump with the following older pump numbers:

• 1016012

• 1016058

• 1016204

These numbers help identify a potential replacement. Confirm the existing pump’s voltage, speeds, amperage, plumbing connections, discharge orientation, and mounting dimensions before ordering.

Have a different number on your pump? Send Whirly Bros clear photos of the pump label, motor label, and plumbing connections. We’ll help review the replacement options.

One-Speed or Two-Speed Operation

The 5235208-S uses a two-speed motor and can be connected for:

• Two-speed operation: low and high speeds controlled by a compatible spa control system.

• One-speed operation: one selected motor speed connected according to the motor wiring diagram and spa control requirements.

Wiring must follow the diagram supplied with the actual motor. Converting the wiring does not make this a variable-speed pump.

Check These Details Before Ordering

Electrical specifications: Match the 230V supply, motor speeds, and electrical requirements to your existing equipment and spa control.

Plumbing connections: This pump uses nominal 2-inch connections. The outside diameter across the pump threads is approximately 3 inches; nominal plumbing size is different from the measured thread diameter.

Discharge orientation: Compare the outlet position with your existing pump and available plumbing space.

Mounting dimensions: Check the motor base, mounting-hole positions, and pump connection heights. Motor designs and mounting bases may vary between production versions.

Cord and unions: Plan to reuse suitable existing components or purchase compatible replacements separately. Inspect their condition and fit before installation.

Match More Than Horsepower

Horsepower labels can differ between older and newer spa pumps. A matching “2 HP” label alone does not establish compatibility.

Use the part number, voltage, high- and low-speed amperage, motor frame, plumbing dimensions, and pump performance requirements together when selecting a replacement.

Frequently Asked Questions

Does this pump include a power cord or unions?

No. The power cord and pump unions are sold separately. Existing components may be reused if they are compatible and in suitable condition.

Can I use this pump with a one-speed spa control?

Yes, it can be wired for one-speed operation when the selected motor speed and electrical requirements are compatible with the control system. Follow the motor’s wiring diagram.

Can it operate on 115V or 120V?

This is a 230V pump. It is not intended for a 115V or 120V supply.

Does it replace Balboa 1016012, 1016058, or 1016204?

These numbers are documented supplier cross-references for the 5235208-S. Verify your existing pump’s specifications and installation dimensions before purchasing.

Will it bolt into the same mounting holes?

Mounting-base designs can vary. Check the supplied pump’s dimensions against your existing installation; mounting adjustments may be necessary.

Is this a dedicated circulation pump?

This is a two-speed spa jet pump. Its low speed can provide circulation and filtration in a compatible system. It should not be treated as a universal replacement for a small dedicated circulation pump.
