Air Operated Diaphragm Pumps - Granzow

DEPA-Air Operated Diaphragm Pu
Metal pumps, series M
DEPA air operated diaphragm pumps made
of cast metal have established themselves
over decades in various industrial areas.
World-wide installations on ships, well-known
ceramic manufacturers, in spray painting
systems in the automobile industry and in
mining are amongst our many varied
applications.
In the range of cast metal pumps more than
20 models with different sizes and designs are
available to serve almost any type of application.
The sturdy cast metal construction ensures high
abrasion resistance when pumping abrasive

media, a low flow resistance due to the high
surface finish, availability throughout a wide
temperature range, excellent corrosion
resistance and a long lifetime.
In combination with the well-established air
control system these compact and powerful
cast metal pumps are easy to transport and
are therefore used as mobile units or stationary
equipment.
During the development of the pumps great
attention was paid to ease of maintenance in
order to minimise downtimes.
Due to the use of stainless steel clamp bands
DEPA air operated diaphragm pumps are clearly
distinguished from other air operated diaphragm
pumps. They can be easily disassembled
without any special tools and keep the
diaphragms evenly clamped.
