These pumps have been designed and manufactured to be used in specific conditions and within
defined limits. The use outside these specifications has to be agreed and approved by the
AlphaDynamic Pumps SA technical service. It must also be considered that, if the pumps are used
outside their technical specifications, the CE Certifications and the warranty are no longer valid.
Furthermore, if the pump is used outside the technical specifications communicated to us at the
moment of the quotation and confirmed in our order confirmation, the customer becomes
responsible for the issue of a new CE Certification.
The pump has to be used only for the applications specified in the order for which AlphaDynamic
Pump SA has selected the model, the construction materials and has tested the pump to respect the
specifications. For other uses, different from those stated in the order, the customer has to send
always a written request to the AlphaDynamic Pump SA technical office, which on its part will reply
in written form. There will not be any warranty for repairs or alterations on the product done by the
users or third parties not specifically authorized by AlphaDynamic Pump SA.
Always shut down the pump before touching or proceeding with any intervention on it or on the
circuit of installation. The pump must be empty of pumped liquid and it must be completely
decontaminated and successfully rinsed with water before any manual operations or disassembling.
Make sure that the electrical system, to which the pump will be connected has, the adequate power
and has the correct protection devices (e.g. Grounding, Life safe).
Always switch off the electrical supply before working on the pump for maintenance or part
substitution. Always keep an extinguisher next to the pump installed.
Always pay maximum attention to the execution of maintenance activities on pumps and on the
connected circuits when they are used with dangerous liquids.
The use of an electric starter is recommended. A simple switch can be insufficient to start and stop
the electric motor connected to the main electric system. An appropriate starter:
· can prevent accidental starting after a failed attempt to start
· is a safe switch, protected against water
· protects the electric motor against overloads due to a short circuit (a fuse only protects the wires)
· resists against starting in overload on the motor, preventing dangerous electric arc and early wear
of the electrical contacts
