The Model 545 is an advanced performance, solvent prep scale delivery module that has been designed to compete with the most expensive prep scale pump systems on the market in reliability and performance without the high cost. The Model 545 has all of the features of the Model 540 but Model 545 is intended to be stand-alone metering pump. In order to make gradients, a gradient option needs to be purchased, either "Low pressure proportioning valve controller" or "High pressure gradient controller". Please contact us for more detail and also for the different material, in Titanium or in PEEK as well.
Option #1: Mechanical Pump Assembly only
Option #2: Pump + Servo Controller + Hydraulic Module (Transducer + Purge valve + Damper)
Option #3: Pump + Servo Controller + Hydraulic Module without Damper
Option #4: Pump Assembly in Chassis
Option #1 to #4 are the typical configurations and we will make a custom configuration for your specifications.
