🔧 LX Lingxiao 48WUA 2.0 HP Spa Pump (48WUA2002C-II NF) — Dual-Speed 230V 48 Frame Bracketless Jet Pump
Primary 2-Speed Jet Pump for Sundance & Jacuzzi Spas — Bracketless Replacement for 6500-343 with High/Low Speed Operation
♨️ Product Overview
The LX 48WUA2002C-II(NF) is a 2.0 HP dual-speed bracketless jet pump manufactured by Guangdong Lingxiao Pump Industry Co., Ltd. (LX). The “NF” (No Feet) designation means this pump ships without a built-in mounting base, requiring a separate pump bracket (Sundance/Jacuzzi part 6000-532, sold separately) for installation. This bracketless configuration is specifically designed for Sundance and Jacuzzi hot tubs that use a removable bracket mounting system.
As a dual-speed pump, this model delivers powerful high-speed jet massage at 10.0 amps and quiet low-speed filtration/circulation at 3.0 amps — all on 230V/60Hz. The 2-speed design makes this the primary pump (Pump 1) in Sundance and Jacuzzi spas, where it runs on low speed for daily filtration cycles and switches to high speed when the jets are activated. It directly replaces the Sundance/Jacuzzi OEM part number 6500-343 (also known as 6500-343S) and its many predecessors.
Both suction and discharge ports are 2″ Male Buttress Thread (MBT), with center suction and side discharge. The wet end can be rotated in 90-degree increments to match any existing plumbing layout. Motor speed is 3450 RPM on high and 1725 RPM on low. The compact 48-frame thru-bolt motor features pure copper windings, Texas Instruments thermal protector, anti-creep bearings, and a Viton/Silicon Carbide/Graphite mechanical seal. Two 2″ pump unions are included.
⚠️ Important: This is a 230V-only pump. It is NOT convertible to 115V. Verify your spa operates on 230V (220V–240V) before ordering.
⚠️ Primary Pump (Pump 1): This 2-speed pump is the primary jet pump in Sundance/Jacuzzi spas. If you need the single-speed secondary pump (Pump 2), see the 48WUA2002C-I(NF) (replaces 6500-341).
⚠️ Marin & Capri Models: Multiple retailers advise against using this LX replacement on the Sundance Marin (2000–2003) and Capri models. For these spas, use the OEM 6500-343S from Sundance/Jacuzzi instead.

❓ Frequently Asked Questions
Q: What horsepower is this pump? A: LX rates this pump at 2.0 HP output power (with competitive power at 3.5 HP and input power at 3.08 HP). The equivalent Sundance/Jacuzzi OEM pump (6500-343) is rated at 2.5 HP continuous / 4.2 HP brake HP. These are different rating methods for the same class of pump. When comparing replacements, match by amperage (10.0/3.0A at 230V) rather than stated horsepower.
Q: What does “NF” or “Bracketless” mean? A: “NF” stands for “No Feet.” This pump ships without a built-in mounting base or feet. It requires a separate pump bracket (Sundance/Jacuzzi part 6000-532, sold separately). If you need a pump with built-in feet for direct mounting, order the 48WUA2002C-II (without “NF”) instead.
Q: Is this a 115V or 230V pump? A: This pump operates exclusively on 230V / 60Hz. It is NOT convertible to 115V.
Q: Is this the primary (Pump 1) or secondary (Pump 2) pump? A: This 2-speed pump is the primary jet pump (Pump 1) in Sundance and Jacuzzi spas. It runs on low speed for daily filtration and switches to high speed for jet operation. The single-speed secondary pump (Pump 2) is the 48WUA2002C-I(NF), replacing 6500-341.
Q: Will this fit my Sundance or Jacuzzi hot tub? A: This pump replaces the Sundance/Jacuzzi OEM part number 6500-343/6500-343S, used in Altamar (1998–2003), Bahia (11/2002+), Calypso (1997), Cameo/Optima (1997–2003), Maxxus (1999+ Pump 1), Telluride (1998–04/1999), and Jacuzzi J-230, J-270, J-280, J-325, J-335, J-345, J-355, J-360, J-365, and J-385. Note: in mid-2010, Sundance transitioned some models to a 56-frame pump (6500-367). Verify your existing pump’s frame size before ordering.
Q: Can I use this on the Sundance Marin or Capri? A: Multiple retailers specifically advise against using this LX replacement on the Sundance Marin (2000–2003) and Capri models. For these spas, the OEM 6500-343S is recommended instead. Contact Parts4Tubs for guidance if you are unsure.
Q: What is the amperage difference between this LX pump and the OEM Sundance pump? A: The LX pump draws 10.0A (high) / 3.0A (low). The Sundance OEM Theramax pump (6500-343) is rated at 11.0A (high) / 3.3A (low). The LX replacement draws slightly less current than the original — this is within normal operating range and does not affect performance.
Q: How many wires does this 2-speed pump use? A: This pump uses a 4-wire connection: Green (Ground), White (Common/Neutral), Black (High Speed), and Red (Low Speed). Ensure your spa control system supports 2-speed pump operation with a 4-wire cord.
Q: Do I need to buy a mounting bracket separately? A: Yes — the 6000-532 universal pump bracket is required for Sundance/Jacuzzi installations and is sold separately.

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.

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.
