Model AA:  High Pressure Liquid Metering Pumps

Download pdf brochure

 1. Flow rates between 0.2 to 10 mL/min. with reciprocating piston design
 2. High pressure capabilities, to 5000 psi.
 3. Corrosion resistant materials
Two Basic Models
There are two different models based on the same Model AA construction.  Each covers a specific flow and pressure range.  If possible, choose a model you will use in the upper range of its flow rate capacity.
For a listing of Model AA pumps which run off 230VAC, click on Model AA 230VAC.
Three Materials of Construction
Most Model AA pumps are available using three different materials of construction; type 316 stainless steel, CTFE, 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).
