Fitted to brands such as MAAX, Cascade, Trinity, Monalisa and AMC Winer along with many other newer spa brands appearing in the European market. A wide range of models across the range means you can often replace more expensive pump brands with these great alternatives. They are often used as circulation pumps on hot tubs and swim spas but can also be found fitted to many whirlpool baths as well.

The JA50 is a self drain centre discharge pump. It would be most commonly used as a circulation pump on hot tubs and swim spas but can also be found fitted to many whirlpool baths as well.

The JA50 is a close match for DXD-8 A if you are looking for a replacement.
