Designed with stainless steel fluid path, CP Class Positive Displacement Piston Pumps cover wide range of flows, with pressures up to 25,000 psi. Advanced pressure control algorithms ensure consistent bed density and prevent pressure over-shoot by allowing user to select wide range of process parameters. Used for LC column packing, pumps come in 5, 12, 24, 100, and 300 mL/min versions, and enable complete PC control and status via RS-232 and Micro USB 2.0 ports.
