🎛️ Sundance Jacuzzi TheraMax Spa Pump 6500-343 — 2.5 HP Dual-Speed 230V 48-Frame
Primary 2-speed OEM jet pump for Sundance 880 series and Jacuzzi J-300 series spas
📋 Product Overview
The Sundance/Jacuzzi TheraMax 6500-343 is the factory OEM 2.5 HP continuous duty (4.2 HP uprated) dual-speed primary jet pump engineered for Sundance and Jacuzzi spa systems. Manufactured by Balboa Water Group to Sundance/Jacuzzi specifications, this 48-frame baseless pump operates at 230V/60Hz and draws 11.0 Amps on high speed and 3.3 Amps on low speed, delivering powerful hydrotherapy jets at full power and quiet, energy-efficient filtration at low speed. The TheraMax series has been the standard pump platform for Sundance Spas since 1997, replacing the earlier Aqua-Flo “XP” series (1997-1999) and Vico “Ultra Jet” (1994-1996) designs. The baseless motor design mounts using the separate 6000-532 bracket that wraps around the motor casing, and the rotatable wet end repositions in 90-degree increments to match any existing plumbing configuration without modifications. As the primary (pump #1) in multi-pump Sundance spa systems, this 2-speed pump provides both high-speed jet performance and low-speed circulation/filtration in a single unit. It serves Sundance, Jacuzzi (branded as Piranha), and Gatsby spas, and is the direct replacement for numerous legacy TheraMax, TheraFlo, and Aqua-Flo XP 2-speed pump part numbers.

Important Notes
How do I Replace a Hot Tub Pump?
Here's a general step-by-step guide on how to replace a hot tub pump. Keep in mind that the specific steps may vary depending on your hot tub's make and model, so it's essential to consult your hot tub's manual for model-specific instructions. If you're not comfortable with this procedure, it's a good idea to seek professional assistance.
Materials You'll Need:
- Replacement pump
- Pipe wrench
- Adjustable wrench
- Screwdriver
- Pipe sealant (thread tape or plumber's putty)
- PVC primer and cement (if you have PVC plumbing)
- Teflon tape (for threaded connections)
Procedure:
-
Turn Off the Power: Before you begin, ensure the hot tub's power supply is turned off at the circuit breaker or disconnect switch. Safety should always be a priority when working with electrical components.
-
Drain the Hot Tub: If your hot tub is not already empty, you'll need to drain it. Follow your hot tub's manual or manufacturer's instructions for proper draining. (You might not need to do this if you can lock the pump off with the gate valves)
-
Locate the Pump: Identify the location of the existing pump in your hot tub. It's usually located near the equipment area or in a designated pump compartment.
-
Disconnect the Electrical Wiring: Carefully disconnect the electrical wiring from the old pump. This typically involves removing the electrical conduit cover, unscrewing wire nuts, and disconnecting the wires from the terminals. Be sure to note the wire connections or take a picture for reference when connecting the new pump.
-
Disconnect the Plumbing: Depending on your hot tub's plumbing setup, you'll need to disconnect the plumbing connections to the pump. Use a pipe wrench or adjustable wrench to loosen and remove the fittings. Be prepared for some water spillage when disconnecting the plumbing.
-
Remove the Old Pump: Once the electrical and plumbing connections are detached, carefully remove the old pump from its mounting position. Some pumps may be secured with mounting brackets or bolts.
-
Prepare the New Pump: If the new pump is not pre-assembled, you may need to attach fittings, unions, or adapters to match your hot tub's plumbing. Ensure that you use the appropriate sealant or Teflon tape on threaded connections to prevent leaks.
-
Mount the New Pump: Position the new pump in the same location as the old one and secure it in place using the mounting brackets or bolts.
-
Reconnect Plumbing: Reconnect the plumbing to the new pump, ensuring that all connections are tight and secure. If your hot tub uses PVC plumbing, use PVC primer and cement to bond the connections properly.
-
Reconnect Electrical Wiring: Reconnect the electrical wiring to the new pump, following the notes or pictures you took earlier. Make sure all wires are properly connected and secure.
-
Turn On the Power: Restore power to the hot tub by switching on the circuit breaker or reconnecting the disconnect switch.
-
Test the Pump: Turn on the hot tub's pump to ensure that it's working correctly. Check for any signs of leaks or irregularities in the plumbing connections.
-
Refill the Hot Tub: Once you've confirmed that the new pump is functioning properly, refill the hot tub with water.
-
Check for Leaks: Inspect the plumbing connections for any leaks. If you find any, turn off the pump, drain the tub again, and reseal the connections as needed.
-
Monitor: Keep an eye on the pump and plumbing for the next few days to ensure everything is functioning correctly and that there are no further issues.
Remember that this is a general guideline, and the specific steps may vary based on your hot tub's design. If you're unsure or uncomfortable with any aspect of this process, please do get in touch, happy to help.
How do I know what size hot tub pump I have?
Determining the size of your hot tub pump is an important step when it comes to maintenance or replacement. To find out the size of your hot tub pump, follow these steps:
-
Check the Manual: The easiest way to determine the size of your hot tub pump is to consult the owner's manual or user documentation that came with your hot tub. The manual typically contains detailed information about the specifications and components of your hot tub, including the pump.
-
Look at the Pump Housing: If you don't have access to the manual or it doesn't provide the information you need, inspect the pump itself. Most hot tub pumps have a label or plate on the pump housing that displays essential details, including the pump's model number, manufacturer, and specifications. You can then send that to me or Google it.
-
Measure the Pump: If the label is missing or damaged, you can measure the pump's dimensions. Measure the diameter of the pump's wet end (the part where the water flows) and the length of the wet end. These measurements can help identify the size and capacity of the pump.
-
Consult the Manufacturer: If you can't find the information on the pump or in the manual, contact the hot tub manufacturer or a reputable dealer. Provide them with your hot tub's model and serial number, and they should be able to identify the correct pump size for your specific hot tub.
-
Online Research: You can also search online using the pump's model number or hot tub's make and model. Many manufacturers provide detailed information about their products on their websites, and you may find specifications for your pump model.
Once you have determined the size and specifications of your hot tub pump, you can proceed with maintenance, repairs, or replacement if necessary. Keep in mind that replacing a hot tub pump with the same size and capacity as the original is crucial to ensure proper water circulation and filtration in your hot tub. If you're unsure about any aspect of this process, get in touch, always happy to help.
