Standard 2" pump union compatibility
Upgrade your spa experience with this powerful and efficient 4-horsepower, 2-speed Turbostream pump—perfect for replacing most existing units. Designed to fit standard 2-inch pre-installed pump unions, it offers easy installation and broad compatibility with most 4 HP and 4.5 HP spa systems.
Powered by a compact 48-frame motor, this pump is lighter and smaller, making it easier to handle and position during setup. Its slimmer profile is ideal for tight spaces where a 56-frame motor might not fit. For added versatility, the wet end can be rotated in 90-degree increments, allowing it to adapt to a wide range of plumbing configurations.

Understanding Pump Connection Sizes
Hot tub pump plumbing sizes are nominal, meaning the labeled size doesn’t match the actual outside diameter of the threads. This can be confusing when replacing your pump.
To confirm if your setup uses 2-inch connections, measure the outside diameter of the threaded intake or discharge on your old pump using a tape measure.
- A 2-inch connection will measure approximately 3 inches across on the outside.
This quick check can help ensure you order the correct replacement and avoid installation issues.

Electricity as Water Through a Hose
Think of electricity like water flowing through a hose:
- Amps are the amount of electricity flowing, similar to the water flowing through the hose.
- Volts are like the water pressure that pushes the electricity through the wire.
Just like higher pressure pushes more water, higher voltage pushes more electricity. Too much pressure or flow can cause problems, just like an overloaded circuit.
In short:
- Amps = The flow of electricity
- Volts = The pressure pushing the electricity

Choosing the Right Frame Size
Most spa pumps come in one of two standard sizes: 48-Frame or 56-Frame. When replacing your pump, it’s important to match the frame size to your existing one—this ensures the mounting holes on the motor and wet end line up properly.
Not sure which frame you have? A quick way to check is by measuring the distance between the bolts on the motor face:
- 48-Frame: about 91 mm (3.58 inches) between bolts
- 56-Frame: about 104 mm (4.09 inches) between bolts
Matching the frame size makes installation much easier and avoids alignment issues.
Installing an oversized pump in your hot tub can cause significant damage.
To avoid choosing the incorrect pump, confirm if it’s a 48 frame or 56 frame, then use the Voltage rating and high-speed Amperage rating listed on the old pump's label to find the correct replacement. The amperage rating is listed with both high/low speed for a 2-speed pump. We do not recommend ordering based solely on the horsepower rating, as this can vary based on how the manufacturer rates the motor.
NOTE: This pump does NOT come with pump unions or union gaskets
