Pump mixer


The BTSP and BTDP-series pumps offer an optional magnetically-driven stirrer for comprehensive, in-situ fluid mixing across a wide range of operating pressures and temperatures. The stirring mechanism consists of a permanent magnet, which is actuated by a variable-speed DC motor and is affixed through the pump cylinder's end cap. A dedicated controller unit provides functionalities for initiating, halting, and modulating the stirrer's rotational speed, which can reach up to 1,500 RPM.
