ASI 546 series metering pumps are intended for manufacturing & engineering applications requiring
high pressure metering and accurate fluid flows. The 546 series metering pump features one of four
standard flow ranges: 250, 500, 1,000 and 1,500 mL.
The 546 series has been optimized for 24/7 production conditions with less than 5% peak-to-peak
pressure pulsation. For applications that require absolute minimum pressure pulsation, please
consider 545 series pumps.
All pump types feature:
Self-priming pump head
Integral prime/purge assembly for changing solvent quickly
Wash option for USE when running buffers
User interface consists of touchscreen display or Modbus RTU (RS485 or USB-serial)
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.
Option #1 to #3 are available for OEM customers.
