DG Low Flow Rate Pump Head
The DG series is specifically designed for low-flow fluid transfer across multiple channels, enabling the simultaneous transfer of 1-48 channels in a compact and user-friendly configuration. The pump head consists of three parts: the frame, rollers, and cartridge(s). The rollers in the pump head are made of 304 stainless steel, while the cartridges are available in POM and PVDF to cater to different requirements. The spring-loaded cartridge automatically adjusts the pressure gap to different tubing.
Features
- Multi-channel transfer
- low transfer pulsations and maximum flow consistency between channels
- Individually loadable cartridge for easy installation and replacement of tubing
- Occlusion can be adjusted automatically through the spring-loaded cartridge system to fit different tubing
- 6-roller and 10-roller pump heads available: 6 rollers offer a larger flow range and longer tubing lifespan while 10 rollers transfer with less pulsation and ensure maximum flow rate consistency
