BJ-RZ01B Stepper Motor Peristaltic Pump, 152 mL/min (CAT#: STEM-AL-2634-ZJF)

The BJ-RZ01B is a stepper motor peristaltic pump designed for small-flow liquid transfer. Its transparent PPS pump-head housing allows the operating condition to be observed. A rotation-locking mechanism helps maintain stable long-term operation. The rollers are made from POM for consistent mechanical performance. A four-rotor arrangement provides moderate pulsation characteristics. The pump uses a 42-type stepper motor as its drive source. It is intended for incorporation into medical devices and liquid-transfer analytical instruments. The compact assembly supports controlled pumping through compatible thick-wall tubing.
