LM40A Box-Type Peristaltic Pump, 1,295 mL/min (CAT#: STEM-AL-2626-ZJF)

The LM40A is a box-type peristaltic pump designed for controlled liquid transfer. Speed is adjusted through a keypad panel or rotary encoder. An LED display provides real-time speed information, while indicator lights show operating status. The pump supports keyboard, communication, foot-switch, and analog control methods. It can be configured with SN15, FG16, or YZ-series pump heads. Multiple compatible tubing sizes allow the system to accommodate different flow requirements. External inputs provide control of speed, direction, start, and stop functions in the applicable operating modes. The enclosed drive design is suitable for integration into laboratory or equipment-based fluid handling systems.
