to 12.5 mL/min. with reciprocating piston design. Expanded low flow rate
range with optional micrometer |

|
Two
Basic Models |
|
|
|
There are two different models based on the
same Model AA VS 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.
|
|
|
|
All Model AA VS pumps run off either 115
or 230VAC.
|
|
|
|
Two
Materials of Construction |
|
|
|
Model AA 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). |

*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.
Minimum flow rates are stated per channel, maximum flow rates are stated
with combined channels.
