🎛️ LX Lingxiao 56WUA400-2/6 Spa Jet Pump — 4.0 HP 2-Speed 230V 56-Frame 2-Pole/6-Pole 2″ MBT Side Discharge | Ultra-Low 1.0A Low Speed
Energy-saving 2-pole/6-pole motor draws just 1.0 amp on low speed — eliminates the need for a separate circulation pump
♨️ Product Overview
The LX 56WUA400-2/6 is a 4.0 HP, 230V, 2-speed, 56-frame jet pump with a specialized 2-pole/6-pole motor that draws an ultra-low 1.0 amp on low speed — dramatically lower than the standard 56WUA400-II’s 4.4 amps on low speed. This unique motor configuration runs at a lower 1150 RPM on low speed, resulting in cooler operating temperatures, longer pump life, and significantly lower energy consumption during filtration and heating cycles. On high speed, the pump delivers a full 12.0 amps for powerful hydrotherapy jet performance. Manufactured by LX Lingxiao (Powerful Water Technology Limited), this WUA series pump features 2″ MBT intake and side discharge connections (measures approximately 3″ outside diameter across threads), a mechanical seal for watertight continuous operation, and a rotatable wet end to match your existing plumbing. The pump includes unions in the box but does NOT include a pump cord — reuse your existing cord or purchase a 6-wire AMP cord separately. The ultra-low low-speed amperage eliminates the need for a separate circulation pump and plumbing in many spa configurations, making it an efficient single-pump solution for both jets and filtration/heating.
⚠️ CRITICAL: This pump (56WUA400-2/6) is NOT the same as the standard 56WUA400-II. The low speed amperage, RPM, and wiring are different. The 56WUA400-2/6 requires a 6-wire connection, while the standard 56WUA400-II uses a 2-wire configuration. Always verify your existing pump’s exact model number before ordering. If you need the 2-wire standard version, see the 56WUA400-II instead.
⚠️ HP Rating Note: This pump is rated at 4.0 HP by LX Lingxiao. In the spa industry, this can also be expressed as approximately 2.5 HP continuous duty or 4.0 HP brake-torque horsepower. For replacement matching, always compare amperage ratings — this pump draws 12.0A on high speed and 1.0A on low speed at 230V.
⚠️ Plumbing Variants: The 56WUA400 family is available in multiple wet end configurations: 2″ × 2″ (this pump), 2″ × 2-1/2″, and 2-1/2″ × 2-1/2″. This pump is the 2″ × 2″ version — verify your plumbing size before ordering.

Installation Notes
⚠️ Verify Pump Model: Confirm your existing pump is the 56WUA400-2/6 (6-wire, 1.0A low speed) and NOT the standard 56WUA400-II (2-wire, 4.4A low speed). Check the label on your old pump.
⚠️ Wiring Diagram: Do NOT put wires back in the same positions as your original pump. Follow the wiring diagram provided with the new pump — terminal positions can change between models.
⚠️ 6-Wire Configuration: This pump requires a 6-wire connection. If your spa uses a 2-wire configuration, you need the standard 56WUA400-II instead.
⚠️ Plumbing Size: This is a 2″ × 2″ version. Measure across your existing wet end threads to verify (~3″ / 3-1/16″ = 2″ plumbing; ~3-7/16″ = 2-1/2″ plumbing).
⚠️ Flooded Suction Required: Pump must be installed below water level.
⚠️ Never Run Pump Dry: Running without water destroys the mechanical seal.
⚠️ Wet End Rotation: Loosen thru-bolts, rotate wet end to match existing plumbing, and retighten.
⚠️ Bleeder Barb: If your original wet end uses a flat-head screw style bleeder barb, you will need a new wing-nut style bleeder barb for the new wet end.
⚠️ GFCI Protection Required: All spa installations require GFCI protection per the NEC.
⚠️ Bonding & Grounding Required: Per NEC requirements.

❓ Frequently Asked Questions
Q: What is the difference between the 56WUA400-2/6 and the 56WUA400-II? A: The most important differences are low speed amperage and wiring. The 56WUA400-2/6 (this pump) draws only 1.0A on low speed using a 6-wire 2-pole/6-pole motor, while the standard 56WUA400-II draws 4.4A on low speed with a 2-wire configuration. Both draw 12.0A on high speed. They are NOT directly interchangeable without wiring changes. Check your existing pump label to determine which version you have.
Q: How do I know if I need the 2/6 or the standard II? A: Check the label on your existing pump. If it says 56WUA400-2/6 or shows 1.0A low speed with a 6-wire connection, you need this pump. If it says 56WUA400-II or shows 4.4A low speed with a 2-wire connection, you need the standard version.
Q: Can the low speed replace a separate circulation pump? A: Yes — the ultra-low 1.0A low speed at 1150 RPM provides sufficient flow for heater circulation and filtration, eliminating the need for a separate circulation pump and plumbing in many spa configurations.
Q: Are unions included? A: Yes — pump unions with O-rings are included. The pump cord is NOT included — reuse your existing cord or purchase a 6-wire AMP cord separately.
Q: Is a cord included? A: No — the pump cord is NOT included. This pump requires a 6-wire cord. Reuse your existing pump cord.
Q: What size is the plumbing? A: Both intake and discharge are 2″ MBT (measures approximately 3″ / 3-1/16″ OD across pump threads). The 56WUA400 family also comes in 2″ × 2-1/2″ and 2-1/2″ × 2-1/2″ versions — verify your plumbing before ordering.
Q: Will this replace a Sundance or Jacuzzi pump? A: Possibly — this pump cross-references with Sundance/Jacuzzi OEM numbers 6500-352, 6500-363, and 6500-365.

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.
