premature wear. The maximum permissible stroke frequencies can be found in the following table. The
pumps can briefly (up to max. one hour) be operated against a closed discharge line. Throttling on the
suction side may damage the pump.

• Before putting the pump into operation as well as after some hours of operation, the
housing bolts [8,9] have to be fixed according to the torque data of the following
schedule, as the elements of construction "settle". Fixing the bolts is necessary as well
after longer periods of stoppage, at extreme temperature variations, after transport and
dismantling the pump.

•
Installation, operation, and maintenance by qualified staff only.
•
Pressure tests of the plant a pump is included in may only be carried out with the pump
disconnected from the pressure on both ports or by using the pressure the pump
develops while operating. The load of a pressure in the plant may damage the pump.
•
Pneumatic diaphragm pumps must not be operated with a positive suction pressure.
•
Depending on the conditions of operation, the liquid conveyed might escape from the
pump through the muffler in case of a diaphragm rupture (muffler has to be renewed).
For further safety requirements the optional equipment diaphragm monitoring and
barrier chamber system are recommended.
•
The state of the muffler has to be inspected regularly, as a blocked muffler can be
forced out of the pump. If this happens, damages of properties and/or persons cannot
be excluded.
•
If the product tends to settle, the pump has to be flushed regularly. For larger solids a
filter has to be installed in the suction line.
•
The relevant effective security advises have to be respected.
•
Pumps of the BIOCOR series must not be submerged.
•
Pools of liquid which appear in the near outer area of the pump have to be inspected on
danger potential, if necessary safety measures are to be taken.
•
Chemical and biological reactions in the product chamber of the pump (mixture of
different substances) and the freezing of the liquid have to be avoided.
•
Especially when deliver critical liquids, wear parts, like diaphragms, should be replaced
within a preventive maintenance.
•
The use of non-original ALMATEC spare parts and structural changes lead to the lapse
of the warranty immediately. When operating such a pump, damages of properties
and/or persons cannot be excluded.
•
The operation of the pump with nitrogen as driving gas is possible. In closed rooms a
sufficient ventilation must be provided.
•
According to the requirements of our 14001-certification, every unit which is send to
ALMATEC for diagnosis or maintenance reasons has to be accompanied by a filled out
decontamination-sheet. Otherwise a processing is not possible. The decontamination-
sheet is enclosed to this manual. Please pay attention to the further safety regulations.
