BJ30 Stepper Motor Peristaltic Pump, 1,295 mL/min (CAT#: STEM-AL-2632-ZJF)

The BJ30 is a stepper motor peristaltic pump for liquid transfer in analytical and medical equipment. It uses a 57-type stepper motor to provide controlled rotational movement. The drive is designed for low-noise and stable operation. Its configuration supports applications requiring consistent small-flow or moderate-flow liquid delivery. The pump can be paired with SN15, SN25, YZ1515X, YZ2515X, YZ1515S, YZ2515S, and FG-16 pump heads. Several standard tubing sizes are supported for flexible fluid-path selection. The motor-driven format is suitable for incorporation into instruments and automated systems. The design emphasizes operational stability, service life, and repeatable pumping performance.
