💡 LX WTC50M Superior Spec Circulation Pump – 0.33 HP Quiet Operation

Whisper-Quiet 24-Hour Filtration – Superior Wellness OEM Specification

♨️ Product Overview

The LX WTC50M Superior Spec is a whisper-quiet 0.33 HP single-speed circulation pump specifically designed for continuous operation in hot tubs and spas. Its low-speed, quiet performance makes it perfectly suited for 24-hour filtration systems where silent background operation is essential.

‘Superior Spa Spec’ means this circulation pump has no air switch fitted inside, making it ideal for spas controlled by electronic control systems that don’t require manual air switch operation. This is the OEM specification used in Superior Wellness hot tubs.

Delivering 0.25 kW of efficient circulation power whilst drawing only 1 amp, the WTC50M runs at a quiet 1,400 RPM – significantly slower than standard circulation pumps – providing excellent water movement with minimal noise. With a maximum flow rate of 240 L/min and 3.8-metre head pressure, this compact unit ensures effective filtration circulation without disturbing spa users.

Featuring a centre suction design with self-draining capability, this pump automatically drains when the motor shuts off, protecting both the pump and your system from potential damage. The thermally protected motor with 7µF capacitor ensures reliable, long-lasting continuous operation.
