Special order item**
Wavemaster® 4000 jet pump was used on the 1998-2002 Hot Spring Hot Spot RLX, SLX. Also used on the 2000-2002 Hot Spring Solana X, 2003-current Hot Spring Solana TX and RX spa models. The shroud on your old pump will fit onto this replacement. It is used to exhaust the pump's heat from the rear of the pump motor. The two speed function means that the low speed is for automatic filtration and high speed for hydrotherapy. ***Replaces old style, part 37334***
