Hydraulic system: Two dual pistons in series pumps with proprietary servo-controlled variable stroke design, power transmission by ball screws, smooth motion control of pistons for active damping. High resolution piston movement control for smooth and reliable motion. 
Two pistons in series design for increased reliability. Fast defill function for improved intake and delivery performance. Solvent selection for optimum flow and composition accuracy. Auto tuning of the delivery cycle for compensation of elasticity and solvent volume change effects (compressibility, thermal expansion, mixing contraction). Automatic purge function for ease of use and unattended preparation of the system. Jet Weaver for optimum mixing performance with a minimum of delay volume. Solvent selection valve for method flexibility. Seal wash for continued high lifetime of pump seals for buffer applications. The Binary pump is designed for highest performance, GLP compliance and easy maintenance.
