High-Volume Performance for Hot Tub & Swim Spas:

The WTB250 series is engineered for high-volume water movement and long-term reliability in demanding spa and pool environments and high-flow swim training environments. Primarily designed to power counter-current systems, these pumps deliver a consistent river-jet volume flow that transforms a standard pool into an swimming treadmill. Available in single or three-phase options, the WTB range provides professional-grade protection and the sustained power necessary for serious uninterrupted swimming,

Key Features & Benefits

• High-Volume Flow, Ideal for River Jets: Optimised to move a massive 1210 litres of water per minute, providing the consistent, smooth current required for professional-grade swim spa training.
• Maximum Efficiency, Minimum Noise: The hydraulic design is optimised for a high flow rate of up to 1210 l/min ensuring powerful water displacement without unnecessary energy waste or excessive noise.
• Built to Withstand Harsh Chemicals: The pump's wet end is constructed from high-strength engineering plastic, specifically chosen for its ability to resist corrosion and wear from salt, chlorine, bromine, and other common spa chemicals, ensuring a long service life.
• Flawless Moisture Protection: The motor stator features advanced resin-sealed packaging technology. This provides a superior moisture barrier and improved heat dissipation compared to conventional motors, perfect for humid pool equipment rooms or hot tub cabinets.
• Safe, Leak-Free Operation: A wear-resistant mechanical seal system prevents leaks, while the motor shaft is completely isolated from the water to ensure electrical safety and prevent internal corrosion.
• Versatile Power Options: Available in both single phase (230V 13.7A) and three phase (400V 4.9A) configurations suited for residential and commercial spa systems.
• Fixed Impeller Failure Protection (WTB250T): Three phase variants of the WTB(T) feature a key and nut system to secure the impeller, eliminating the risk of the impeller spinning loose even if the motor is accidentally wired in reverse during setup.

Technical Specifications & Operating Limits

Why choose the WTB250/T?

One of the most common failure points in hot tub pumps is moisture ingress or chemical degradation, the WTB250 and WTB250T Swimming Training Pumps are able to stand up to these challenges, taking the abuse of continuous operation and harsh environments in its stride.
