Specifications

Waterway’s unique Variable Speed Swim Spa System utilizes  economical 2-speed pumps, a specially designed NEO 2100 control system and a VSDU (Variable Speed Distribution Unit) to achieve variable flows at very low cost. The swimmer can now adjust all jets simultaneously, with up to 6 swim speeds, allowing for gentle low buoyancy aerobics all the way to an aggressive swim.

 U.S. Patent Number US9,573,038
  • Achieves variable speeds ideal for swim spa use.
  • Works with either two or three Viper swim pumps.
  • Control system can support one or more swim jets,
    and additional spa and circulation pumps.
  • Doesn’t require expensive variable speed pumps, additional controls and inverters to operate!
  • Easy to use specially designed NEO 2100
    control system
  • Innovative 2 ½” VSDU (Variable Speed
    Distribution Unit)
  • Two 2 ½” serviceable check valves
  • Economical 2-speed pumps to operate
A specially designed NEO 2100 Spa Pack controls the sequence of each pump.
For example: 1st Speed – Pump 1 actuates on low speed equaling roughly 140 GPM, 2nd Speed – Pump 1 & 2 actuates on Low Speed equaling roughly 250 GPM, 3rd Speed – Pump 1 actuates on High Speed equaling roughly 290 GPM and so forth (see chart below).  The flow from all pumps are mixed together in the VSDU and then evenly re-distributed to each of three swim jets.
