Mini peristaltic pump OEM MN4 (Flow rate ≤ 1400ml/min)

Product Overview

MN4 Peristaltic Pump is specially designed for OEM (Original Equipment Manufacturer) applications requiring high precision and compact dimensions. It is a direct upgrade from the popular 204K pump series, retaining the same mounting hole positions for easy replacement while significantly improving durability and performance.

Detailed Structure

The product features an optimized structure for easy assembly, disassembly, and maintenance. Below is the detailed component drawing of the MN4 pump:
