The WP-400-I is the only pump in the WP series that is one speed and uses only the high speed.

The LX WP series hot tub pumps are one of the most common two speed pumps used on Chinese manufactured hot tubs and swim spas as well as many other newer hot tub and swim spa brands appearing on the European market. 

The WP series of pumps will often serve as a circulation and booster pump, the low speed will circulate to heat and run filter cycles while the high speed will deliver a higher volume of water through hot tub jets. 

This pump features the high speed only. Making it best to use as a boost pump for powering the Jets. Using a separate pump for circulation.

The WP Series is also ideal for use with

• Weak corrosive liquids such as weak acids (without solid granules) Liquid temperature: +5-60
• For circulating fluids for use in workshops for cooling.

The WP series is also the pump of choice for both Jacuzzi and Sundance spas, replacing the discontinued Theramax pumps and can also be used to replace similar higher priced pumps from other manufactures at a more economical price.
