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.

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.
