šŸŒ”ļø Fluid-o-Tech PB 401 Magnetic Drive High-Temperature Rotary Vane Pump

Ā 

The Fluid-o-Tech PB 401 is a specialized, compact magnetic drive rotary vane pump from the RotoflowĀ® line, primarily distinguished by its ability to handle high-temperature liquids up to () when equipped with appropriate seals. It is ideally suited for closed-loop thermal transfer systems, cooling applications, and other industrial processes where conventional rotary vane pumps would fail due to heat.

Crucially, the PB prefix indicates a Magnetic Drive design. This means the motor power is transferred via magnetic coupling rather than a traditional mechanical shaft seal. This eliminates the dynamic shaft seal entirely, removing the primary point of leakage and wear, offering superior reliability, zero leakage, and maintenance-free operation, especially with challenging or hot fluids. This model provides a flow rate up to 100 LPH (26 GPH) and utilizes a flange mount for secure installation.
