LINGXIAO Pump Specs Compared
Voltage and Power
The LINGXIAO 0.35 HP 230V Spa Circulation Pump operates on 230V power with a current draw of 1.0A. It is designed for higher voltage systems. In contrast, the LINGXIAO 110V 116 GPM Bath Pump runs on 110V power. It draws 9.0A to achieve its performance. You must match the pump to your spa’s electrical supply. Using the wrong voltage can damage the unit or the spa. Check your existing pump’s label or your spa’s manual to confirm the required voltage before purchasing. This is the most critical compatibility factor for installation.
Flow Rate
Flow rate determines how quickly water moves through your spa’s plumbing. The LINGXIAO 110V 116 GPM Bath Pump offers a maximum flow rate of 116 gallons per minute. This is a high volume for circulation. The LINGXIAO 0.35 HP 230V Spa Circulation Pump provides a maximum flow rate of 63.4 GPM. If you need stronger water movement for jets or filtration, the 110V model delivers nearly double the flow. The 230V model is sufficient for standard circulation needs but moves less water overall.
Physical Dimensions
Space constraints matter when replacing an old pump. The LINGXIAO 110V 116 GPM Bath Pump is more compact. It measures 5 inches wide, 7 inches high, and 7 inches long. The LINGXIAO 0.35 HP 230V Spa Circulation Pump is larger. It measures 6.5 inches wide, 7.68 inches high, and 11.9 inches long. The 230V model also has a long snout design, which affects how it fits into tight pump boxes. Measure your available space carefully. The 110V model fits into smaller enclosures more easily.
Compatibility
Both pumps are designed to replace specific OEM models. The LINGXIAO 0.35 HP 230V Spa Circulation Pump is compatible with OEM#6500-905, #6500-907, and #6500-913. It is made by the same factory as your old pump to ensure fit. The LINGXIAO 110V 116 GPM Bath Pump is compatible with OEM #34-402-5002 and #1431501-03. You must check the model number on your current pump to ensure you buy the correct replacement. Neither pump is universally compatible with all spas.
Warranty and Support
After-sales support differs between the two models. The LINGXIAO 0.35 HP 230V Spa Circulation Pump comes with a 1-year full replacement support. The manufacturer offers 7/24 technical support and emphasizes reliability with full machine replacement instead of repairs. The LINGXIAO 110V 116 GPM Bath Pump includes a 12-month warranty. It also provides 24-hour response time for customer questions via Amazon email. Both offer one year of protection, but the 230V model explicitly mentions full replacement without repair attempts.
Choose your LINGXIAO pump model
You need high flow for jets
The LINGXIAO 110V Bath Pump delivers 116 GPM. This flow rate is nearly double the 63.4 GPM of the circulation model. If your spa relies on strong jet pressure for hydrotherapy, this higher volume output is essential. The 9A current draw supports this increased performance for active water movement.
You have a 230V system
Your spa likely requires 230V power for proper operation. This circulation pump matches that voltage exactly. It draws only 1.0A, which is safer for lower-amperage circuits. The 0.35 HP motor provides steady circulation without the high electrical load of the 110V model, ensuring compatibility with your existing wiring.
You want long-term reliability
This model offers a full replacement warranty rather than a limited repair term. The manufacturer highlights 50 years of experience and 24/7 technical support. The pure copper motor and creep-resistant bearings are designed for extended life. This comprehensive support structure provides greater peace of mind for long-term ownership and maintenance.

Frequently asked questions
Can I install the 230V circulation pump in a 110V spa?
No. The LINGXIAO WTC50M Circulation Pump requires a 230V power supply. Your spa must have compatible 230V wiring. Using this pump on a 110V circuit will prevent it from operating. You must match the voltage rating of the pump to your spa’s electrical system for safe and proper function.
Which LINGXIAO pump is better for jet pressure?
The LINGXIAO 110V Bath Pump (WBC150) is better for jet pressure. It delivers 116 GPM of flow. This is significantly higher than the circulation pump’s 63.4 GPM. If you prioritize strong hydrotherapy jets, the bath pump provides the necessary volume. The circulation pump is designed for water movement, not jet force.
Do both pumps use the same plumbing connections?
Yes. Both the LINGXIAO 110V Bath Pump and the 230V Circulation Pump include 1.5-inch PVC unions. This standard connection size allows for straightforward installation into most spas. You do not need to change your existing plumbing fittings. Both units are designed to fit standard 1.5-inch ports directly.
Is the circulation pump UL certified?
Yes. The LINGXIAO WTC50M Circulation Pump is UL certified. This certification indicates it meets specific safety standards for electrical equipment.

The LINGXIAO 110V Bath Pump (WBC150) measures 5 inches in width, 7 inches in height, and 7 inches in length. It weighs 15 pounds. These compact dimensions allow it to fit into standard equipment boxes. The smaller footprint compared to larger pumps makes it suitable for spas with limited space.
Does the circulation pump have a copper motor?
Yes. The LINGXIAO WTC50M Circulation Pump features a pure copper motor. This material choice contributes to quiet operation and durability. Copper motors are known for efficient heat dissipation. This aligns with the bath pump’s similar construction, ensuring reliable performance in both models.
