AOD (air operated diaphragm)
pumps available from ESE.BV come
in seven sizes to handle flow rates
from a few cc/min to 52m3/h.

Selection of the correct type is
important to boost performance and
reduce maintenance. Help with
pump selection is now possible with
the PSI computer selection program
available over the Internet.

The program starts with flow
rates, heads, viscosity and fluid.

Various models are displayed to meet
specifications. The user is able to
compare various sizes of pump to
see which best suits the application.

A complete pump model is shown
and displays suggest wetted parts for
the AOD pump. The device has few
air valve components. The result,
says the company, is a correctly
selected pump with low maintenance
air valve design.
