Core | CO2 Pumps
A high-capacity laboratory pump engineered for advanced research and pilot-scale applications. Designed for the precise delivery of liquid CO₂ and other fluids, it supports high flow rates across a wide range of uses—from natural product extraction and supercritical processing to corrosion testing and materials evaluation. Its robust performance makes it ideal for larger laboratory setups and small-scale production environments in pharmaceuticals, materials science, and process development.
The system offers dual operation modes: flow mode, which utilises a high-precision servo motor and can be integrated with a flow meter for accurate and consistent dosing; and pressure mode, which automatically adjusts flow to reach or maintain a set pressure within closed systems or during delivery through fixed nozzles.
With a proven dual-piston design and robust construction, this pump strikes the perfect balance between throughput, accuracy, and energy efficiency—supported by over 30 years of Core Separations’ expertise in high-pressure CO₂ delivery systems.
