LX Lingxiao 48WUA 1.5 HP Spa Pump (48WUA1501C-II NF) – Dual-Speed 48 Frame Bracketless Jet Pump

💧 LX Lingxiao 48WUA 1.5 HP Spa Pump (48WUA1501C-II NF) – Dual-Speed 48 Frame Bracketless Jet Pump

Compact, Whisper-Quiet Dual-Speed Power — The Ideal Sundance & Jacuzzi Replacement Pump

♨️ Product Overview

The LX 48WUA1501C-II(NF) is a 1.5 HP dual-speed jet pump manufactured by Guangdong Lingxiao Pump Industry Co., Ltd. (LX). Designed specifically for the North American spa market, this WUA series pump delivers high-speed massage jet performance and low-speed filtration/circulation in one compact, energy-efficient package. The “(NF)” designation indicates this is the bracketless (no feet / baseless) version, designed for spas that use a separate mounting bracket such as the Sundance/Jacuzzi 6000-532.

This pump operates on 115V/60Hz power, drawing 13.8 amps on high speed and 3.8 amps on low speed. The 2.0 HP input power delivers 1.5 HP output power through an efficient 48-frame thru-bolt motor with pure copper windings. Both the suction and discharge ports are 2″ Male Buttress Thread (MBT), with center suction and side discharge configuration. The volute can be rotated in 90-degree increments for flexible plumbing installation.

This pump is one of the most widely used aftermarket replacement pumps for Sundance Spas and Jacuzzi hot tubs, directly replacing models in the J-200 and J-300 series as well as Sundance Solo, Caprio, and Tango models. It also commonly replaces Aqua-Flo XP2e and Waterway pumps of the same frame size, voltage, and amperage. The pump features Viton/Silicon Carbide/Graphite mechanical seals and is UL, cUL, and ETL certified for safety.

⚠️ Important: This is a bracketless pump — it does not include a mounting bracket or feet. If your spa requires a bracket, purchase the 6000-532 universal mounting bracket separately, or reuse your existing bracket.

Discharge Rotation

The volute can be rotated in 90-degree increments to position the discharge at 12, 3, 6, or 9 o’clock. The pump ships with discharge at the 12 o’clock (top) position. To rotate, loosen the thru-bolts, reposition the wet end, and retighten evenly.

Installation Notes

⚠️ Pump must be installed below water level (flooded suction) for proper operation.

⚠️ Never run the pump dry — this causes immediate seal damage and voids the warranty.

⚠️ Ensure proper grounding and bonding per NEC requirements.

⚠️ GFCI protection is required by code for all hot tub and spa installations.

⚠️ Power cord is NOT included — reuse your existing pump cord or purchase a compatible replacement.

⚠️ This pump is bracketless. You must use a separate mounting bracket (6000-532) or reuse your existing bracket.

⚠️ If your original wet end has a bleeder barb with flat-head screws, you may need a new-style wing nut bleeder barb. Verify before installation.

⚠️ Use the included unions for the best seal. Unions from different manufacturers may vary slightly in fit.

⚠️ Motor capacitor placement (single or dual, top or side mount) may vary between production runs. Ensure sufficient clearance in the pump compartment.

❓ Frequently Asked Questions

Q: What horsepower is this pump? A: This pump has an input power of 2.0 HP and an output power of 1.5 HP. LX Lingxiao rates their pumps by both input and output power. When comparing to other manufacturer’s pumps, always match by amperage (13.8A high speed at 115V) rather than stated horsepower, as HP rating methods vary.

Q: Will this fit my Sundance or Jacuzzi hot tub? A: This pump is a direct replacement for Sundance/Jacuzzi models using the 6500-345 or 6500-845 pump, including J-200 and J-300 series Jacuzzi models and Sundance Solo, Caprio, and Tango models. Verify your existing pump’s voltage (must be 115V), amperage (13.8A high speed), frame size (48 frame), and port size (2″) before ordering.

Q: What voltage does this pump require? A: This pump requires 115V / 60Hz (standard North American household voltage). All electrical installation must be performed by a licensed electrician. Using the wrong voltage will damage the motor and void the warranty.

Q: Is this a single or dual speed pump? A: This is a dual-speed (2-speed) pump. High speed powers the jets for hydrotherapy massage, and low speed provides energy-efficient circulation for filtration and heating. It can also be wired for single-speed operation if needed.

Q: What size are the ports? A: Both suction and discharge use 2″ Male Buttress Thread (MBT), which measures approximately 3-1/16″ (78mm) across the outside of the threads. The suction is on the center front face, and the discharge is on the side.

Q: Does this pump include a mounting bracket? A: No — this is the bracketless (NF) version without feet. If your spa requires a bracket, purchase the 6000-532 universal mounting bracket separately or reuse your existing bracket from the old pump.

Q: Does a power cord come with this pump? A: No — the power cord is sold separately. Reuse your existing pump cord if compatible. Replacement cord options include the 2-speed AMP connector cord (30-1001C or 21087) or mini JJ type cord, depending on your spa pack connection type.

Q: Does this include pump unions? A: Yes — two 2″ pump unions are included with this pump. LX recommends using the included unions for the best seal, as unions from different manufacturers may vary slightly.

Q: Can I rotate the discharge direction? A: Yes. The volute can be rotated in 90-degree increments (12, 3, 6, or 9 o’clock positions). The pump ships with discharge at the 12 o’clock (top) position.

Q: What is the difference between 48WUA1501C-II and 48WUA1501C-II(NF)? A: Both have identical pump performance and specifications. The “(NF)” designation means “No Feet” — the bracketless version designed for Sundance/Jacuzzi spas that use a separate mounting bracket. The version without “(NF)” includes feet/base for direct mounting.

Q: Does this replace the Aqua-Flo XP2e pump? A: Yes — this LX pump is commonly used to replace Aqua-Flo XP2e 1.5 HP 115V 48-frame pumps with 2″ inlet and discharge (part number 06115000-1040 and others). Also replaces select Waterway pumps (3420610-1A, 3420610-10).

Q: What warranty is included? A: This pump includes a 1-year manufacturer warranty. The motor serial number label (located on the exterior of the motor housing) is required for all warranty claims. Contact Parts4Tubs for full warranty terms.

Q: How do I know if my pump needs replacing? A: Common signs include unusual noise (grinding, screeching, humming without rotation), water leaking from the seal area, reduced jet flow, the motor repeatedly tripping the circuit breaker, or the motor overheating.

Q: Do I need a GFCI breaker? A: Yes, GFCI (Ground Fault Circuit Interrupter) protection is required by the National Electrical Code (NEC) for all hot tub and spa installations.
