MID 1980's to Circa 1993

Jacuzzi Whirlpool used This WHITE pump from their mid 1980's to 1993. This WHITE pump is sealed and the whole must be replaced if it fails. The motors are specifically made to mate with these pumps.
 
Circa 1993 to 2001 (note below)

 From 1993 to 2001 Jacuzzi Bath Spas commonly used the "J" and "K" Series of Pumps; each a patented design. A key way to identify what you have is the union where the pump connects to the plumbing. It looks like:

Note the cone shape surface of the pump fitting face. If your pump (wetend) has this style union, you have either the 1jp, 2jp or 3kp pump.

 
Which J Series Pump does your spa have? This should help:

The ONE Pump/Motor Spas used the 2500-255. This is a 2 speed motor operating on 115v. All JWB spas with only one pump/motor uses this pump/motor.  Click Here  The motor has two windings so on low operates heater/filter and on High gives you jet action.
OR

The TWO Pump Spas either had Two Identical Pumps or One larger than the other. If your spa has identical pump/motors you have the 2500-250. This is a 1 speed motor operating only on 230v. Most larger spas had 2 identical pump/motors.  Click Here When low/filter/heating, the #1 pump operates. When you press HIGH the #1 stays on and the #2 comes on doubling your jet action.

(Has Front Snout) (Pipe Connects in front Center)

If One Pump/Motor Is Larger than the other, smaller is 2500-250 seen at Click Here and the larger is the 2500-251 seen at Click Here. This was the design on most Platinum Series spas and some others. Both motors are 1 speed operating on 230v. The #1 pump is the smaller pump and operates the low/filter/heat cycle. When you turn the High jets on, the #1 stays on and the #2 or -251 pump/motor turns on, giving you full power.
   
 
Late 1998 to End Of JWB Spa Production

In 1998 starting with the Pinnacle Model, Jacuzzi Bath Spa division introduced the generic pumps for the larger spas. Because they blended over time you must check the pump union to confirm what you have if you have a Premium or Platinum Model 2 or 3 pump model. A key way to tell the 3KP (3hp) Jacuzzi pump from the generic pumps is that the Jacuzzi pump top discharge is in the center of the pump while the generic style pump being introduced has a side discharge. Second is the Jacuzzi cone shape plumbing fitting verses the flat generic shape fitting mentioned above.

What's the difference between J-Pumps?

J-Pump is first generation and heavier. The "light" generation has less plastic. The J-pump is being phased out and in very limited supply. Most use the "light" generation.
