The MCP350 is similar in design to the MCP650 pump also sold by Swiftech. It is smaller, quieter and produces even more head pressure than the MCP650 but has lower free-flow capabilities than its big brother. Swiftech claims the MCP350 is ideal for smaller ID systems, especially when using more than one waterblock in series. The MCP650 on the other hand may be better suited for ½” ID tubing systems that perform better with higher flow rates and have minimal flow resistance.
