• Flow rates between 0.003 to 40 mL/min. with various liquid ends using a reciprocating piston design.

  • High Pressure capabilities, to 6000 psi.

  • Corrosion resistant materials.

Three Interchangeable Pump Heads

To maximize the versatility of the Model 2 Optos pump, three different liquid end assemblies were developed. Each interchangeable liquid end provides specific flow rates and pressure capabilities and can be changed in a matter of minutes.

Two Corrosion Resistant Materials of Construction

Model 2 pumps are available using two different materials of construction; type 316 stainless steel and PEEK®.

To choose your pump, use the charts below to locate the desired materials of construction, then locate the model you will typically use in the upper range of its capacity (if possible). Click on the link in the charts for detailed information.

*Maximum flow rate specifications are based on theoretical volume displacement; actual flow rates will vary depending on such factors as fluid viscosity, compressibility and temperature.

Plus: Minimize Pulsation, Monitor Pressure

Add Plus to your Optos Series pump to integrate a pulse damper to further reduce pulsation, and have the ability to monitor pressure and set high and low pressure limits. Plus is available on L and S piston pumps.
