Castle Hot Tubs

Waterway 1 Speed 3HP 56 Frame Side Discharge 2.5×2


Available on backorder



Found on hot tubs such as: Artesian, Artesian Island Spas, Hot Tubs Direct, Knightswood Leisure, Touch Spas, Catalina, Hydropool, Hotspring, Hotspot, Southwest Spas and many more.
(Although listed on the Artesian website as a 4.8bhp, and indeed they are correct, our 3HP single speed Waterway pump shown here has a 5HP wet end. If you combine this with the power ratings of the motor it comes out as a near on perfect match. We have carried out this experiment ourselves recently).
Additional Notes: This pump can be found in many different Hot Tubs in various forms. It has 2 inch outlets and will work in place of either Waterway, Vico, Sta-Rite, GE, Emerson, A.O Smith, ITTor Aqua-flo and in most cases the unions will wind straight on. This pump is used for the boost jets operation. You may find that your pump has a smooth body as opposed to this style of pump but as long as the ratings are the same it will still work. In most cases you will find that the wet end is the same but the motor may be made by a different company.

You may be finding it difficult to find an exact match for your current pump. If you need our help then just give us a call or email and we will happily advise if this pump can be adapted to work with your system. Our range of pumps we offer is designed to get over most obstacles.

Unions to be purchased separately
