Dual Piston Isocratic Pump

Chrom Tech LD & PR Class Dual Piston Isocratic Pumps

Dual piston for minimal pulsation
Pulse dampener
Self-flushing pump heads and prime purge valve
Pressure monitoring with automatic pressure compensation
Built-in leak sensor
Stainless steel or PEEK fluid path

Our reliable dual piston pumps feature reciprocating pistons, which drastically minimizes pulsation. In combination with a low dead volume pulse dampener, our dual piston pumps are virtually pulse-free. With max flow rates up to 300 mL/min, our dual piston pumps are versatile for a diverse range of applications.
