This high-pressure pump system is specifically designed for methanol injection testing under variable load and pressure conditions. With a flow range from <2 l/min to 20 l/min at a constant 1,000 bar, it ensures stable and repeatable performance for research and development purposes. The unit features an ATEX Zone 1 certification, a TA-Luft-compliant seal system with leakage detection, and an external oil pressure supply for dynamic flow control. A magnetically coupled pre-feed pump and a custom suction line with integrated filter and flow stabilizer ensure safe, precise, and cavitation-free operation with aggressive media like methanol.
