History Lesson

Jacuzzi's Designed Wetend/Pumps

Mid 1980's to 1993

JWB used their "white" pumps. The wetend is one piece and white with a gray plate. The wetend can be connected to a GE, Century, or other motor.


JWB used their patented "J" and "K" pumps. The 3 distinguishing designs was their "swivel" union connection, a center discharge, and a low suction union on their "J" pumps. The main identification is the swivel union on both J and K pumps.

Late 1998 to 2001

In 1998 JWB started introducing a "generic" wetend. Starting with the Pinnacle Model Hot Tub the spa division introduced the generic pump for the larger model spas. Because they blended these into production over time you must check your pump union to confirm what you have if you have a Premium or Platinum Model with 2 or 3 pumps. A key way to tell the 3KP (3hp) pump from the generic pumps is that the pump top discharge is in the center of the pump while the generic style pump being introduced have a side discharge. Second is the cone shape plumbing fitting verses the flat generic shape fitting mentioned above.
