Each person working on the ALMATEC air‐operated diaphragm pumps concerning installation, start‐up,
handling or maintenance has to read this manual completely and in an attentive way and has to follow all
mentionedproceduresandsafetynotes.
GENERALDESCRIPTIONOFTHEMACHINE,APPROPIA TEUSEANDRESIDUALDANGERS
The ALMATEC E‐Series pumps are oscillating positive displacement pumps and
are based on the functional principle of double diaphragm pumps. The basic
configuration consists of two external side housings with a center housing
between them. Each of the side
housings contains a product chamber which is
sealed against the center housing by a diaphragm. The two diaphragms are
interconnected by a piston rod. Directed by an air control system, the
diaphragms arealternatelyloaded with compressedair sothat theymove back
and forth. In the first figure, the compressed
air has forced the left‐hand
diaphragm towards the product chamber and displaced the liquid from that
chamber through the open valve at the top to the discharge port. Liquid is
simultaneously drawn inbythe right‐hand diaphragm, thusrefillingthe second
product chamber. When the end of the
stroke is reached, it reverses
automaticallyandthe cycleis repeatedin theoppositedirection.In thesecond

proper storage conditions are important for a trouble free operation later. The pump has to be protected
from wetness, coldness, dirtying, UV‐radiation and mecha nical influences. The following storage conditions
arerecommended:
‐Steadyventilated,dustandvibrationfreestorageroom
‐Ambienttemperaturebetween15°C(59°F)and 25°C(77°F)witharelativehumiditybelow65%
