🔩 LX Lingxiao 56WUA300-I Spa Pump — 3.0 HP Single Speed 230V 56-Frame | Reliable High-Performance Jet Pump

Proven power and reliability from over 40 years of dedicated spa pump engineering

📋 Product Overview

The LX 56WUA300-I is a 3.0 HP single-speed jet pump manufactured by Guangdong Lingxiao Pump Industry Co., Ltd. (LX) — a globally recognized spa pump manufacturer with over 40 years of dedicated pump engineering experience. Operating at 230V/60Hz with 10.0 Amps at 3,450 RPM, this 56-frame side-discharge pump delivers flow rates up to 188 GPM with a maximum operating pressure of 0.3 MPa (approximately 43.5 PSI). The 56WUA300-I features 2″ center suction and 2″ side discharge ports with Male Buttress Thread (MBT) connections, and is specifically designed as a universal aftermarket replacement for many popular spa pump brands — including the Gecko Aqua-Flo XP2e 3.0 HP 56-frame single-speed pump, Waterway Executive series, and other OEM pumps of equivalent specifications. The motor features pure copper winding construction for superior heat dissipation and longer service life, a Texas Instruments thermal protector for reliable overload protection, and anti-creep bearings with high-temperature grease oil for quiet operation. The Viton/Silicon Carbide/Graphite mechanical seal provides exceptional resistance to high and low temperatures as well as chemical corrosion — delivering durable, leak-free performance in demanding hot tub environments. The wet end can be rotated in 90° increments to match your existing plumbing configuration. Two sets of 2″ unions are included for easy installation. Certified UL, CUL, and ETL for safety compliance. Backed by a 1-year manufacturer warranty from Lingxiao.

Extensive OEM Replacement Compatibility List (via 56WUA300-II Platform)

The following part numbers are documented by SpaGuts as pumps that the 56WUA300 platform can replace. Note: these are primarily for the dual-speed -II version; single-speed -I replacement requires matching the single-speed configuration:

💡 Single Speed vs. Dual Speed: The 56WUA300-I is the single-speed version. The 56WUA300-II is the dual-speed version with identical wet end, frame, and physical dimensions. The -II can also be wired as a single-speed pump by connecting only the high-speed terminal and using a 3-wire single-speed pump cord. If your spa requires both high-speed jet operation and low-speed filtration, consider the 56WUA300-II instead.

💡 LX Wet End Note: LX wet ends are designed specifically for LX pump motors. LX wet ends will NOT replace Waterway or Aqua-Flo wet ends, and vice versa. Always replace the complete pump assembly, not just the wet end, when switching from another brand to LX.

🛠️ Installation Requirements

Mounting

Requirement	Specification
Mounting Position	Horizontal — on a level surface
Mounting Base	Included (floor mount)
Location	Below water level (flooded suction)
Surface	Solid, level, vibration-dampening
Ventilation	Adequate clearance around motor for air cooling
Capacitor Clearance	Allow extra space for motor capacitor(s) — may be single or dual mounted externally

Plumbing

Connection	Size
Suction	2″ MBT (Center)
Discharge	2″ MBT (Side)
Unions	Included — 2 sets of 2″ unions

Installation Notes

⚠️ Pump must be installed below water level (flooded suction) — ensure pump casing is completely filled with water before starting

⚠️ Never run pump dry — causes seal damage and motor overheating

⚠️ Unions from different factories might vary slightly — use the included LX unions for the best seal

⚠️ If you have a barb fitting screwed into the front of your pump, check for compatible replacement fittings

⚠️ Ensure proper grounding and bonding per NEC requirements

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

⚠️ Pump cord is NOT included — use your existing pump cord or purchase a new 3-wire single-speed pump cord

💡 Wet End Rotation: The discharge is at the 12 o’clock position by default. It can be rotated to 3 or 9 o’clock positions by loosening the bolts at the back of the motor.

💡 Wire Color Note: When replacing pumps from other manufacturers, wire colors for high and low speed may be opposite from your old pump. Given the schematics show identical terminal numbers and internal motor wiring, match wire terminal placement based on terminal designations (High/Low/Common/Ground) rather than wire color.

🔄 Maintenance Guide

Routine Maintenance

Task	Frequency	Notes
Check for leaks	Monthly	Inspect around seal area and union connections
Inspect unions	Monthly	Tighten if needed — use appropriate plumbing tools
Clean motor openings	Quarterly	Keep all ventilation openings free from debris
Check amperage draw	Annually	Should read approximately 10.0 A
Inspect capacitor(s)	Annually	Check for signs of swelling, leaking, or corrosion
Verify GFCI operation	Monthly	Push test button to verify GFCI interrupts power

Warning Signs — Replace Pump If:

• Unusual noise (grinding, screeching, or humming without rotation)
• Water leaking from the mechanical seal area
• Motor repeatedly trips the circuit breaker
• Noticeably reduced water flow or weak jets
• Motor overheating or burning smell
• Capacitor failure (motor hums but won’t start)
• GFCI trips without test button being pushed

Seal Replacement

Detail	Specification
Seal Type	Viton / Silicon Carbide / Graphite
Replacement	Replace at first sign of leakage from the seal area

❓ Frequently Asked Questions

Q: What horsepower is this pump? A: This pump is rated at 3.0 HP, operating at 3,450 RPM on 230V/60Hz with a 10.0 Amp draw.

Q: Is this a single speed or dual speed pump? A: This is a single-speed pump (56WUA300-I). If you need a 2-speed pump, the 56WUA300-II is the dual-speed version with identical physical dimensions and wet end (10.0/3.5 Amps).

Q: Will this replace my Aqua-Flo XP2e pump? A: Yes, the 56WUA300-I is commonly used to replace the Gecko Aqua-Flo XP2e 3.0 HP 56-frame single-speed pump with 2″ inlet and 2″ discharge. Verify your existing pump’s amperage (~10A), voltage (230V), frame size (56), and port sizes (2″) before ordering.

Q: What size are the ports? A: Both suction (center) and discharge (side) are 2″ MBT (Male Buttress Thread).

Q: What voltage does this pump require? A: 230V / 60Hz single phase. All electrical installation must be performed by a licensed electrician.

Q: Does this pump include unions? A: Yes, two sets of 2″ unions are included. A pump cord is NOT included — you will need to use your existing cord or purchase a new 3-wire single-speed pump cord separately.

Q: Can I rotate the wet end to match my plumbing? A: Yes, the discharge can be oriented at 12, 3, or 9 o’clock positions. Loosen the bolts at the back of the motor, rotate the wet end, and retighten securely.

Q: What brand of motor is in this pump? A: Lingxiao uses pure copper winding motors with Texas Instruments thermal protectors. The specific motor brand may vary (US Motors, AO Smith Century, GE, or others) as pump manufacturers reserve the right to change motors without notice. Functionality remains the same.

Q: What type of seal does this pump use? A: Viton/Silicon Carbide/Graphite mechanical seal — resistant to extreme temperatures and chemical corrosion for long-lasting, leak-free performance.

Q: What is the difference between 56WUA300-I and 56WUA300-II? A: The -I is single-speed (10.0A, 3-wire cord). The -II is dual-speed (10.0A high / 3.5A low, 4-wire cord). Both share the same wet end, frame, and physical dimensions. The -II can also be wired as a single-speed by connecting only the high-speed terminal.

Q: What warranty is included? A: 1-year manufacturer warranty from Guangdong Lingxiao Pump Industry Co., Ltd. Contact Parts4Tubs for full warranty terms.

Q: How do I know if my pump needs replacing? A: Signs include unusual noise (grinding, screeching), water leaking from the seal area, reduced water flow or weak jets, the motor tripping the circuit breaker, motor overheating, or the motor humming but not starting (capacitor failure).

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.
