VEVOR SPA Pump 1.5 HP 110V
The VEVOR SPA Pump is a 1.5 HP circulation pump designed for hot tubs and home spas. It offers a stated maximum flow of 107.5 GPM (approximately 407 L/min) and a max head lift of 54.13 ft (16.5 m) at high speed. The unit uses two 1.5-inch connectors intended for straightforward plumbing integration. Manufacturer references include OEM part numbers for Gecko, Watkins, and Balboa, which assists in compatibility checks for common control systems and plumbing configurations.
Operationally, the pump targets even water movement to maintain consistent temperature and filtration performance. The combination of high flow and significant head lift suggests suitability for medium-sized hot tubs or applications where longer plumbing runs and higher resistance are present. Installation considerations include matching union sizes and confirming electrical compatibility with existing 110–120V hot tub wiring.
LINGXIAO WBC150 Bath Pump 110V
The LINGXIAO WBC150 is specified as a 110V/60Hz, 9.0A pump with a flow rate of 116 GPM and 1.5-inch plumbing unions included. The product lists compatibility with OEM numbers such as #34-402-5002 and #1431501-03, which helps when replacing like-for-like components. The motor uses pure copper windings and includes a thermal protector component to limit overheating risk.

Design features reference extensive capacitor testing and an anti-creep bearing intended to extend life and reduce noise. The included unions can simplify field replacement by reducing the need for additional fittings. Important checks before installation include verifying motor amperage against circuit capacity and confirming that the pump’s flow characteristics match the hot tub’s jet and heater requirements.
LINGXIAO WCH150 1.5HP 115V Pump
The LINGXIAO WCH150 is described as a 1.5 HP, 115V bath pump with 1.5-inch connections. The manufacturer lists the input power at 1.1 kW and a nominal current around 9 amps. As with the WBC150 model, the WCH150 emphasizes pure copper motor construction and thermal protection circuitry, along with capacitor and bearing durability testing.
This model is targeted for compatibility with multiple OEM references, so it’s suited for users replacing failed motors or upgrading pumps within the same mechanical footprint. When comparing pump models, note the declared horsepower, flow rates, and head capabilities relative to your spa’s plumbing resistance and jet count to ensure adequate performance and heater pairing.
Key Lander WBC150 Bath Pump 110V
The Key Lander WBC150 pump is specified at 9A, 110–120V and carries UL, CUL, and ETL certification notes. Its construction emphasizes a quality copper-wound motor, thermal protection, and capacitor components tested to strict cycles. Two 1.5-inch unions are included to ease plumbing connections.

Certification listings indicate adherence to recognized safety and performance standards, which can be important for compliance and warranty considerations. The product documentation highlights multiple durability tests — charge-discharge cycles and high temperature trials — intended to demonstrate long-term reliability. As with other pumps, successful integration requires checking electrical supply limits and ensuring the pump’s flow and head characteristics match the spa system’s needs.
58117 Spa Heater Assembly M-7
The 58117 M-7 Heater Assembly is a replacement heater for Balboa control systems and related models. It lists multiple cross-reference part numbers and specifies overall length, heating tube length, and diameter. The listing mentions kilowatt and voltage ratings varying by configuration, including references to 110–120V/240V options.
When selecting a heater assembly, confirm the physical dimensions (total length and tube length) and the correct kilowatt/voltage rating for your spa’s control system. Using the wrong wattage or incorrect orientation can reduce heater life or trigger safety cutouts. The product is positioned as a widely used replacement, but installers must verify control compatibility and sensor placement before installation.
Buying Guide For 110 Volt Hot Tub Pumps And Heaters
Selecting the right pump and heater for a 110 volt hot tub requires cross-checking electrical, hydraulic, and control system compatibility. Below are the key factors to evaluate.
Electrical Compatibility
- Voltage and Amperage: Confirm the pump or heater is rated for 110–120V and that your circuit breaker and wiring support the unit’s full-load amps plus startup inrush.
- Certification: Look for UL/ETL/CUL listings for safety compliance in the U.S.
Hydraulic Performance
- Flow Rate (GPM): Match pump GPM to your hot tub’s plumbing and jet count; higher GPM supports more jets but may reduce pressure at individual jets.
- Head Pressure: Verify the pump’s max head lift to ensure it can overcome plumbinglengths, valves, and elevation changes.
- Port Size: Confirm union or threaded port diameter (commonly 1.5″) to minimize adapters and leak points.
Heater Considerations
- Wattage/Kilowatt Rating: Choose a heater sized for the tub’s water volume and expected temperature rise. Higher kW heats faster but requires more electrical capacity.
- Control System Compatibility: Confirm the heater assembly matches your control module (e.g., Balboa VS/EL/TS/GS/BP).
- Physical Dimensions and Sensor Position: Heater length and sensor placement must match your plumbing cavity and sensor housing.
Build Quality And Reliability
- Motor Construction: Copper windings and thermal protectors improve heat tolerance and longevity.
- Capacitor And Bearing Tests: Look for suppliers that publish endurance tests and thermal protection details.
- Noise And Vibration: Anti-creep bearings and quality housings reduce operational noise.
Installation And Serviceability
- Union Type: Pumps that include 1.5″ unions simplify replacements and reduce leak risk.
- Mounting Footprint: Verify physical dimensions align with your existing pump mount or shelf.
- Spare Parts And Support: Confirm availability of compatible seals, capacitors, and heater elements for future repairs.
Performance Trade-Offs
- High Flow vs. Jet Pressure: High-flow pumps move more water overall, while pumps tuned for higher pressure may deliver stronger individual jets. Choose based on whether you prefer circulation/heating efficiency or jet force.
- Power Draw vs. Heat Output: Higher horsepower pumps increase energy draw; match pump size to heater capacity to avoid undersized heaters struggling to maintain temperature.
- Single-Speed vs. Multi-Speed: Single-speed pumps are simpler; multi-speed or variable-speed pumps offer efficiency but require compatible controllers.
Verification Checklist Before Purchase
- Confirm pump amperage and heater kW fit your spa’s circuit capacity.
- Match port sizes and physical dimensions to existing plumbing and mounting points.
- Verify OEM compatibility numbers and control system model for heater assemblies.
- Check included components such as unions and gaskets to reduce installation time.
- Ensure local electrical codes and GFCI requirements are met during installation.
Using the information above will help you choose a 110 volt pump or heater that meets electrical limits, plumbing constraints, and performance expectations. For replacements, OEM cross-reference numbers and physical dimension verification are especially important to ensure a proper fit without additional modifications.
