BJ-RZ1030 Series Stepper Motor Peristaltic Pump, 183 mL/min (CAT#: STEM-AL-2633-ZJF)

The BJ-RZ1030 series is a stepper motor peristaltic pump for small-flow liquid transfer. Its pump-head housing uses ABS or PPS material for structural durability. Four-rotor and eight-rotor configurations are available to suit different pumping requirements. A flexible upper pressure block adapts to compatible tubing dimensions. The tubing path is designed for straightforward replacement during setup or maintenance. A 42-type stepper motor provides the rotational drive. The assembly is intended for integration into medical instruments and liquid-transfer analyzers. Its compact construction supports controlled fluid movement in equipment-based applications.
