The model K48L2a1 appears to be related to a spa pump motor. Here are some details I found:
The Sta-Rite Dura-Jet Spa Pump is a replacement spa pump for the Sta-Rite® or Dura-Jet brand. This is a dual speed pump with ratings: 1.0HP, 115V, 48-Frame, 60Hz, 2.0 inch intake and discharge.
It replaces most DJAYA pumps with similar amp draw and voltage rating. This pump is normally used in Dimension One Spas, Hawkeye Spas, Master Spas, and Great Lakes Spas.
This pump is a good choice for small to medium-sized spas with up to 16 jets. It is a two-speed pump, so you can adjust the flow rate and pressure to your needs. It is also energy efficient, with a low operating cost.
Here are some additional details about the pump:
The motor is a 48 frame induction motor with a capacitor start.
The pump is made of cast iron and stainless steel, which makes it durable and corrosion resistant.
The pump comes with a set of unions, but you will need to purchase hoses separately.
Here are some of the key features of the 4239110-S spa pump:
2-speed operation for efficient water circulation
Cast iron and stainless steel construction for durability
Capacitor start motor for quiet operation
Two sets of 2" unions included
UL, CUL, and ETL certified
If you are looking for a reliable and efficient spa pump, the 4239110-S is a good option to consider.
Here are some of the benefits of using a two-speed spa pump:
You can save energy by running the pump at a lower speed when you don't need as much water circulation.
You can get more precise control over the water flow and pressure.
The pump is quieter at lower speeds.
If you are replacing an old spa pump, be sure to check the compatibility with your spa's plumbing and electrical system. You should also make sure that the pump has the right horsepower and flow rate for your spa.
The part number 4239110-S refers to a Balboa Dura-Jet (or Sta-Rite Dura-Jet) 1.0 HP, 115V, 2-speed spa pump. This is a widely used Original Equipment Manufacturer (OEM) part manufactured by the Balboa Water Group.
This specific pump model has been used by, or serves as a replacement for pumps in spas made by, several manufacturers:
Dimension One Spas
Hawkeye Spas
Master Spas
Great Lakes Spas
Jacuzzi (on certain models, as Balboa also supplies parts for them)
The Dura-Jet line is known for its compact design and is a common replacement part across many hot tub brands that use 2-inch plumbing.
