The Optos series metering pumps deliver high precision and reliability at high pressures. Achieve flow rates from 0.002 to 20 mL/min with ±0.3% reproducibility with Model 1 meters. The reciprocating piston offers precise flow control while an advanced software algorithms control high-resolution stepper motor to maximize flow output and minimize pulsation. Easily set flow rates using the up and down buttons on the solvent-resistant keypad. Remotely control your meter via an analog signal (4 to 20 mA or 0 to 5 VDC) or RS-232. Contact closures allow remote start and stop, flow output (0 to 5 VDC), and pump error output.

Select a pump that uses the upper half of the flow range listed for each pump. Piston cylinder comes available in two materials—316 stainless steel (SS) and PEEK. 316 SS offers excellent chemical and corrosion resistance; use PEEK for extremely corrosive fluids. A fully integrated piston wash system cleans out buffers or solutions which can crystallize and lead to abrasion of the piston seal, shortening the piston seal life.

A pressure differential of at least 25 psi is required on the outlet side of the pump for the valves to operate effectively.
