• Flow rates between 0.01 to 80 mL/min. with various liquid ends using a reciprocating piston design.

  • High Pressure capabilities, to 3000 psi.

  • Corrosion resistant materials.

Three Interchangeable Pump Heads

To maximize the versatility of the Model 3 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 3 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.
