🤫 LX Lingxiao WTC50M-STANDARD Spa Circulation Pump — 0.35 HP 230V 1-Speed 48-Frame 1-1/2″ MBT | Side Discharge

Ultra-quiet 24-hour circulation with energy-efficient operation — includes unions for easy installation

💧 Product Overview

The LX Lingxiao WTC50M-STANDARD is a 0.35 HP (250W), 230V/60Hz, single-speed, 48-frame circulation pump designed for continuous 24-hour operation in hot tubs and spas. This is the STANDARD version with shorter connection threads on the wet end — ideal for Energy Savers Spas, Water’s Edge, Dr Wellness, Keys Backyard, Interspa, and many other spa brands. Manufactured by LX Lingxiao (Powerful Water Technology Limited), a global leader in spa pump manufacturing for over 46 years. This pump features a pure copper motor winding for excellent cooling efficiency and extended motor life, combined with a mechanical seal for watertight long-term continuous operation. The reinforced engineering plastic base provides vibration resistance and corrosion resistance. Both the intake and discharge are 1-1/2″ MBT (Male Buttress Thread). The wet end features a side discharge and center suction, and can be rotated in 90-degree increments to align with your existing plumbing. Two pump unions are INCLUDED — a significant advantage over many competing circulation pumps that sell unions separately. The pump draws just 1.0 amp at 230V for minimal energy consumption during 24/7 operation. UL Certified for the US market. Backed by a 1-year manufacturer’s limited warranty.

⚠️ CRITICAL: STANDARD vs USA Version — Thread Length Difference: The WTC50M-STANDARD has shorter connection threads on the wet end than the WTC50M-USA. This pump will NOT directly replace Sundance / Jacuzzi P/N 6500-907 (Post 7/11/2011) — the threads are not long enough. If replacing a Sundance or Jacuzzi circ pump, use the WTC50M-USA version instead (longer threads/longer snout). Thread pitch, thread type, and union size are the same between both versions — only the thread length differs.

⚠️ HP Rating Note: This pump is sold under various HP designations by different retailers including 0.35 HP, 1/3 HP, 1/8 HP, 1/15 HP, and 1/5 HP — these all refer to the same pump. The actual power rating is 0.35 HP / 250 watts. Different HP designations reflect different rating methods. For replacement matching, always use amperage (1.0A at 230V) rather than HP rating.

❓ Frequently Asked Questions

Q: What is the actual horsepower of this pump? A: The actual power rating is 0.35 HP / 250 watts. Different retailers list this pump as 1/3 HP, 1/15 HP, 1/8 HP, or 1/5 HP depending on the rating method used. They all refer to the same pump. For replacement matching, use amperage (1.0A at 230V) rather than HP rating.

Q: What is the difference between WTC50M-STANDARD and WTC50M-USA? A: The only difference is the connection thread length. The STANDARD has shorter threads; the USA has longer threads (longer snout). Thread pitch, thread type, and union size are identical. The STANDARD works in most spa applications. The USA version is required specifically for Sundance/Jacuzzi spas (post 7/2011) which need the longer threads.

Q: Will this replace my Sundance or Jacuzzi 6500-907 circ pump? A: No — use the WTC50M-USA instead. The STANDARD version’s threads are not long enough for Sundance/Jacuzzi spas. If you already have the STANDARD, you can add vibration pad 27241-004-000 to raise the pump and compensate for the shorter threads, but the USA version is the recommended direct replacement.

Q: Are unions included? A: Yes — 2 pump unions (1-1/2″) are included in the box. This is a significant advantage over many competing circ pumps that sell unions separately.

Q: Is a cord included? A: No — the power cord is NOT included. Compatible AMP cords include part number 402223 (AMP cord for 1-speed operation) or 21086 (60-inch cord). You may also reuse the cord from your existing pump.

Q: This pump has a 115V-style plug — can I plug it into a 115V outlet? A: Absolutely not. This is a 230V pump. The 115V-style plug is used by some hot tub control systems that accept this connector type. You may need to cut the plug off and hardwire the pump, or use a compatible cord for your spa pack.

Q: Can I rotate the wet end to match my plumbing? A: Yes. The wet end can be rotated in 90-degree increments to align the side discharge with your existing plumbing layout.

Q: What is the flow rate? A: LX Lingxiao (the manufacturer) rates this pump at 63 GPM maximum flow rate. Some third-party retailers list 35 GPM. The variance may reflect different test conditions.

Q: Does this replace the Waterway Iron Might? A: The WTC50M has the same 48-frame mounting, 1-1/2″ MBT connections, and similar flow characteristics. However, it is NOT a direct drop-in replacement — mounting hole patterns, dimensions, and wet end designs differ. Compare all specifications before substituting.

Q: What about the 3/8″ barbed fitting on the wet end? A: The barbed fitting sometimes found on the front of the wet end (connected to 3/8″ freeze protection tubing) is NOT included. If your installation requires this fitting, order it separately (6540-171 with o-ring 6540-263).

Q: Do I need a GFCI breaker? A: Yes, GFCI protection is required by the NEC for all hot tub and spa installations.

Q: What warranty is included? A: 1-year manufacturer’s limited warranty. Contact Parts4Tubs for full warranty terms and support.

Most hot tub pumps use Female Buttress Thread (FBT) - 98% of applications.

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:

1. 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.

2. 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)

3. 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.

4. 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.

5. 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.

6. 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.

7. 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.

8. 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.

9. 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.

10. 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.

11. Turn On the Power: Restore power to the hot tub by switching on the circuit breaker or reconnecting the disconnect switch.

12. 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.

13. Refill the Hot Tub: Once you've confirmed that the new pump is functioning properly, refill the hot tub with water.

14. 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.

15. 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:

1. 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.

2. 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.

3. 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.

4. 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.

5. 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.
