GM400-1A Mini Peristaltic Pump – 0–400 RPM Precision Speed Control

The GM400-1A & BPH01 Mini Peristaltic Pump is a compact, high-precision fluid transfer solution designed for laboratory, analytical, and industrial applications. Engineered for reliable and efficient operation, the pump features a 4-roller BPH01 pump head that delivers smooth, consistent flow with reduced pulsation.

The BPH01 pump head incorporates a durable PA6/MoS₂ housing and high-performance IXEF® rollers, providing excellent mechanical strength, wear resistance, and long-term reliability. Its compact design makes the GM400-2A & BPH01 particularly well suited for applications where installation space is limited while precise and stable fluid delivery is required.

Key Features

• Compact Design – Space-saving construction with a small 220 × 115 × 135 mm footprint, ideal for laboratory benches, instruments, and space-constrained installations.
• 20,000:1 Speed Control Ratio – Provides a wide adjustable speed range of 0–400 rpm for precise control of fluid delivery.
• High-Resolution Speed Adjustment – Speed can be precisely adjusted with different resolutions across the operating range:
  • <10 rpm: 0.01 rpm resolution
  • 10–100 rpm: 0.1 rpm resolution
  • 100–400 rpm: 1 rpm resolution
• Versatile Operating Modes – Supports both continuous mode and timer mode, providing flexibility for different liquid-transfer and dispensing applications.
• User-Friendly LCD Interface – The LCD screen clearly displays pump speed, running direction, operating time, and pump status for convenient monitoring and operation.
• Multiple Control Options – The pump can be conveniently operated using the built-in keypad or footswitch, allowing hands-free operation when required.
• Low-Noise Operation – Engineered for quiet performance, making it well suited for laboratories and other noise-sensitive working environments.
• Durable and Efficient Design – Features IP31-rated protection and operates from a 24 VDC, 8 W power supply for reliable everyday use.
• Multiple Tubing Options – Compatible with #13, #14, #19, #16, and #25 tubing, providing flexibility for different flow-rate requirements and applications.
• The GM400-1A supports external or communication control including RS485 and Modbus RTU, but GM400-2A does NOT.
