LX Pump LP150 – 1.5HP – Single Speed (2″x2″)

Product Description

The LX LP150 is a robust 1.5 HP single-speed hot tub pump, designed to deliver both power and efficiency. Equipped with a 4-core plain cable, it offers reliable performance, making it ideal for effective jet action and consistent water circulation.

This pump is fully interchangeable with select Waterway and Aqua-Flo models, providing flexibility for replacements or upgrades. The LX LP150 ensures durability and peace of mind, making it a dependable choice for any hot tub system.

The LX LP150 (1.5HP Single Speed) is a highly versatile pump often used as a more affordable replacement for premium American brands or as a direct swap for Chinese-manufactured spas.

Because it uses a standard 48-Frame motor and 2.0" plumbing connections, it can replace several other models with little to no modification.

Direct Brand & Model Replacements

The LX LP150 is commonly used to replace the following:

• Sundance & Jacuzzi Spas: It is the primary replacement for the discontinued Theramax pumps.

• Aqua-Flo (by Gecko): It can replace the XP2 and XP2e (1.5HP Single Speed models). The wet ends are almost identical in design.

• Waterway: It is a compatible alternative to the Waterway Executive 48-Frame (1.5HP 1-Speed).

  • Note: If your spa has very rigid plumbing and was built before 2008, the Waterway Executive may be trickier to replace.

• Chinese Spa Brands: It is the "factory standard" for brands like Wellis, Blue Whale Spa, Jazzi, Danz, and AMC Winer.

Technical Cross-Check

To ensure a "drop-in" fit, verify these three specs on your old pump:

1. Plumbing Size: The LX LP150 has 2-inch unions. (Measurement: the outer diameter of the actual pump thread will be approximately 78textmm-79mm.

2. Frame Size: It uses a 48-Frame motor (European finned body). This is the distance between the mounting bolts. If your old pump is a larger "56-Frame," you may need to drill new holes in your mounting base.

3. Amperage: The LP150 draws roughly 5.8A. Ensure your existing control box and wiring can handle this (most 1.5HP setups are rated for 6-7A.

Pro-Tips for Installation

• The "Upgrade" Option: If you want slightly more pressure, the LX LP200 (2.0HP) has the exact same physical dimensions and footprint as the LP150. You can often swap to the LP200 for a boost in jet power without changing your plumbing.

• Wet End Rotation: If the "exit" of the pump is pointing the wrong way (e.g., pointing up instead of to the side), you can undo the four bolts on the front and rotate the wet end in 90° increments to match your pipework.

• Cable Swap: Most LX pumps come with an AMP plug. If your spa uses a different plug (like a J&J or molded cord), you can simply unscrew the back plate and swap the cable from your old pump onto the new one.
