DG Low Flow Rate Pump Head
The DG series pump head is designed for precise low-flow fluid transfer across multiple channels, allowing simultaneous operation of 1 to 48 channels in a compact, user-friendly setup. It consists of three main components: the frame, rollers, and cartridge(s). The rollers are made of 304 stainless steel, ensuring durability, while the cartridges come in POM or PVDF materials to meet various application needs. The spring-loaded cartridge automatically adjusts the pressure gap to accommodate different tubing sizes.
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 sizes
- Available with 6-roller and 10-roller pump heads: The 6-roller configuration provides a larger flow range and longer tubing lifespan, while the 10-roller configuration minimizes pulsation and ensure maximum flow rate consistency
