�� Balboa Theramax Spa Pump 4154213-S — 1.5 HP 2-Speed 115V 48 Frame (Jacuzzi / Sundance Replacement) The OEM Jacuzzi Piranha and Sundance TheraFlo replacement — compact 115V plug-and-play jet power for your spa �� Product Overview The Balboa Theramax (Part No. 4154213-S) is a 1.5 HP true rated, dual-speed, 115V/60Hz jet pump designed specifically as the OEM replacement for Jacuzzi® and Sundance® spas. Built on the proven Balboa Water Group / Sta-Rite Dura-Jet (Cascade / DJ) platform, this pump directly replaces the Jacuzzi “Piranha” pump and the Sundance “TheraFlo” / “TheraMax” pump — including the widely used 6500-345, 6500-258, and dozens of other legacy Sundance/Jacuzzi pump numbers. Running at 13.6A on high speed (3,450 RPM) and just 3.6A on low speed (1,725 RPM) on a standard 115V circuit, the Theramax delivers powerful hydrotherapy jets on high and energy-efficient filtration and heating on low — all from a single, compact 48-frame pump. The unique high-efficiency impeller design provides higher flow rates per horsepower than competing pumps in the same class, with the Dura-Jet series rated to exceed 210 gallons per minute. A key design feature of this pump is its baseless (bracketless) configuration — it does not have feet. It mounts using the Sundance/Jacuzzi mounting bracket (Part No. 6000-532, sold separately). This baseless design matches the original Sundance/Jacuzzi mounting system, making it a true drop-in replacement. The multi-directional volute can be rotated in 90-degree increments (12, 3, 6, 9 o’clock positions) to line up with your existing plumbing, and the 3-position drain plug provides complete configuration flexibility. All seals are carbon ceramic with Viton® elastomers — engineered to endure prolonged heat and chemical exposure. With its petite volute, compact 48-frame design, and whisper-quiet operation, the Theramax 4154213-S is verified for use in Jacuzzi® models J-385, J-365, J-355, J-345, J-230, J-335, J-325, J-270, J-280, and J-360, as well as Sundance® models including Solo, Caprio, and Tango. ⭐ Key Features ✅ 1.5 HP True Rated / 2-Speed — High speed (3,450 RPM) for powerful jets, low speed (1,725 RPM) for energy-efficient filtration and heating ✅ 115V / 60Hz — Standard US 115V (110–120V) spa circuit for plug-and-play convenience ✅ OEM Jacuzzi® & Sundance® Replacement — Directly replaces 6500-345 (Piranha / TheraFlo / TheraMax) and dozens of legacy part numbers ✅ Baseless / Bracketless Design — No feet; mounts to Sundance/Jacuzzi bracket 6000-532 (sold separately) for true drop-in replacement ✅ Compact 48-Frame Design — Petite volute fits tight Sundance/Jacuzzi equipment bays ✅ High-Efficiency Impeller — Unique design exceeds 210 GPM flow rates with smaller HP than competing pumps ✅ Multi-Directional Volute — Rotates to 4 positions (12, 3, 6, 9 o’clock) to match existing plumbing orientation ✅ 3-Position Drain Plug — Complete configuration flexibility (3, 6, 9 o’clock positions) ✅ Carbon Ceramic Seal with Viton® Elastomers — Long-lasting performance in prolonged heat and chemical exposure ✅ Whisper-Quiet Operation — Near-silent performance for a peaceful spa experience ✅ 2″ MBT In/Out — Center suction and radial side discharge with ~3.1″ (3-1/16″) thread outer diameter �� Technical Specifications Specification Value Part Number 4154213-S Manufacturer Balboa Water Group / Sta-Rite / Pentair (Dura-Jet / Cascade / DJ platform) Pump Name Theramax (also known as Jacuzzi Piranha / Sundance TheraFlo) Pump Type Jet Pump (2-Speed) Motor Power 1.5 HP (true rated) Speed Settings 2-Speed High Speed RPM 3,450 Low Speed RPM 1,725 Voltage 115V (110–120V) Frequency 60 Hz Phase Single High Speed Amperage 13.6A Low Speed Amperage 3.6A Frame Type 48 (48Y) Suction Port Size 2″ MBT (Male Buttress Thread) Discharge Port Size 2″ MBT (Male Buttress Thread) Thread Outer Diameter Approximately 3.1″ (3-1/16″) Suction Location Center (front face) Discharge Location Radial side — rotatable to 4 positions Seal Type Carbon ceramic with Viton® elastomers Volute Multi-directional mounting — 3-position drain plug (3, 6, 9 o’clock) Mounting Baseless (no feet) — requires bracket 6000-532 (sold separately) Cord Included No — use existing cord or purchase separately Unions Included No — sold separately Primary Replaces Jacuzzi 6500-345 / Sundance TheraFlo/TheraMax Warranty 1-year manufacturer limited warranty ⚡ Electrical Requirements Electrical Spec Requirement Supply Voltage 115V (110–120V) Frequency 60 Hz Phase Single Full Load Amps (High Speed) 13.6A Full Load Amps (Low Speed) 3.6A Minimum Circuit Breaker 20A (for 13.6A high-speed draw) ⚠️ IMPORTANT: All electrical work must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local and state building codes. Hot tubs and spas require GFCI (Ground Fault Circuit Interrupter) protection. A dedicated circuit is required — do not share with other appliances. This is a 115V pump. Do NOT connect to a 230V circuit. If your spa requires a 230V pump, order the appropriate 230V Theramax model instead. Using the wrong voltage will damage the motor and void the warranty. This pump does NOT include a power cord. Use your existing pump AMP cord or purchase a new 2-speed pump cord separately. �� Compatibility Guide This Pump: �� Frame: 48 (48Y) �� Mounting: Baseless — requires bracket 6000-532 �� Suction: 2″ MBT — Center (front face) �� Discharge: 2″ MBT — Radial side (rotatable to 4 positions) �� Thread OD: ~3.1″ (3-1/16″) Discharge Rotation Positions: Position Clock Reference Up (standard shipping position) 12 o’clock Right 3 o’clock Down 6 o’clock Left 9 o’clock Rotation is done by loosening the four long throughbolts at the back of the motor.

If your original pump had an attached base/feet, you will need to order the mounting bracket separately — Part No. 6000-532. If you already have the bracket from your previous pump, you can reuse it. ⚠️ Union O-Ring Note: Multiple sources recommend replacing the union O-rings at the same time as the pump to ensure a leak-free connection. Unions are sold separately. ⚠️ Historical Note: After using the Vico “Ultra Jet” pump from 1994–1996, Sundance Spas began using the Aqua-Flo “XP” series pumps and called them TheraFlo and TheraMax (primarily 1997–1999). The newer design Theramax pumps began to appear on some models afterward. The current 4154213-S is the latest Balboa replacement for all these legacy pump lines. ��️ Installation Requirements Mounting (Per Sta-Rite Dura-Jet Owner’s Manual S377): Requirement Specification Mount Surface Solid, level, rigid, vibration-free Mounting Method Baseless — mounts to bracket 6000-532 (sold separately) Suction Inlet Must be installed below water level (allows pump to prime) Discharge Must be installed below water level (avoids trapped air in discharge line) Throughbolt Torque 25 inch-lbs (29 cm-kg) Discharge Orientation 4 positions: 12, 3, 6, 9 o’clock (adjustable by rotating wet end) Plumbing: Connection Size Suction (Intake) 2″ MBT — Center (front face) Discharge 2″ MBT — Radial side (rotatable) Thread OD Approximately 3.1″ (3-1/16″) Unions Sold separately — required for connection to spa plumbing Installation Notes (From Manufacturer PDF S377): ⚠️ Installation and wiring of pump should only be done by qualified, licensed personnel ⚠️ Pump suction inlet must be below water level at all times — this allows the pump to prime ⚠️ Pump discharge must be below water level at all times — to avoid trapped air in discharge line ⚠️ NEVER run pump dry — running pump dry may damage seals, causing leakage and flooding ⚠️ Do not block jets — doing so may flood the area, causing damage to equipment and water damage to surroundings ⚠️ Trapped air in system can cause explosion — BE SURE all air is out of system before operating or testing equipment ⚠️ Water pressure for test must be less than 25 PSI (172 kPa) ⚠️ Water temperature for test must be less than 100°F (38°C) ⚠️ Ensure proper grounding and bonding per NEC requirements ⚠️ GFCI protection is required by code for all hot tub and spa installations ⚠️ Do not add chemicals to spa system directly in front of pump suction — adding undiluted chemicals may damage pump and voids warranty �� Maintenance Guide Routine Maintenance (Per Manufacturer): The Sta-Rite Dura-Jet owner’s manual (S377) states: No lubrication or regular maintenance is needed.

O-ring gaskets may vary between manufacturers - measure your existing gasket for accuracy. 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.
