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

Built for Heat: Rated for liquid and ambient temperatures up to 50°C, making it ideal for high temperature spa applications.
IP55 Weatherproof Rating: Dust-tight and protected against water spray, meeting UK safety standard for outdoor electrical equipment
Continuous Duty: Designed for Class F insulation and continuous operation. These pumps can handle 24/7 filtration cycles without overheating.
Automatic Thermal Protection: The single-phase WTB250 features built-in thermal protection to automatically shut down the motor if it exceeds safe temperatures, preventing a catastrophic burnout
Pressure Rated: Supports a maximum working pressure of 3 bar, suitable for most domestic and light commercial filtration systems.
