13 TEST CERTIFICATE
All our pumps pass strict quality control, so we can guarantee their optimal operation and reliability.
Absolutely ALL the pumps are tested on out assembly lines with water under normal working conditions and with
the most modern measurement systems. As a sign of this, along with the present manual, we attach a “Test
certificate” adhesive label.
If you should note any fault or shortcoming, you must report the details of the type of fault, the pump model and the
serial no. so that we can check the cause of the problem and thus be able to continue offering you the best quality.
