Introduction
The ALMATEC Maschinenbau GmbH is certified as a modern, quality-orientated enterprise according to
DIN EN ISO 9001:2000. Before release for dispatch, any pump of the A-Series has to undergo an extended
final control. The performance data registered during this are archived in our records and can be read back at
any time.
Before putting any pump into operation, make sure, that the materials of construction are resistant to the
chemical to be pumped. To check this, the exact pump code is required. This code, as well as the serial num-
ber, can be found in the following. Besides, these data are noted on the identification plates on the pump itself.
Pump code Serial-No.

ALMATEC Pneumatic diaphragm pump, A-Series
The number in brackets, which is added to every part mentioned in the following explanations, refers to its
position in the spare part list and the exploded view.
Operation in explosion-proof areas and for inflammable liquids (Reg.-No. PTB: 03 ATEX D004)
For inflammable liquids as well as for applications in explosion-proof areas, only pumps
with housings and fittings in conductive plastic materials may be used. Pneumatic
diaphragm pumps of the A-Series with the housing codes F (PE-conductive) and U
(PTFE-conductive) meet this requirement. The pump has to be grounded. A connection
to ground the pump is included in the center housing [2]. All other housing parts are
connected to the center housing, therefore it is not necessary to ground single parts.
Piping systems and product connections have to be grounded separately. To avoid
ignition hazards the formation of dust deposits on the pumps must be prevented. In
explosion proof areas repair working only after careful inspection of the practicability and
only with appropriate tools. The “X” in the following marking stands for the max. operating
temperature; corresponding to the pump material referring to the technical data on the next page.
