In the approval phase, specific electrical tests are performed on the stators according to meticulous procedures agreed upon by technical executives. 
Besides the tests aiming to verify compliance with electrical and mechanical measurements, efficiency and reliability are also checked with specific tests performed in special atmospheres and extreme conditions.

Once the prototype has passed the electrical tests, it is assembled with a hydraulic part to undergo dynamic tests in water. This test phase is performed in a test tank equipped with devices that can measure a flow rate of up to 120.000 l/sec and a head of 100 m. It is possible to couple this machinery with models having a discharge from Ø2″ to Ø 500 mm and any type of flange.
Now is when the overall performance of the pump and the definitive efficiency of the project are verified. If the results meet the intended goal, the production of a sampling lot can start, otherwise criticalities are examined in order to apply corrective measures until the performances required by the project are met.

Apart from the prototypes, in the test and trial area of Zenit Group the personnel also perform checks on random samples of the production line, or specific reports requested by the client, for example for models which will be used in particularly hard conditions.

By doing this, Zenit works every day to give its clients a high-quality product and guarantee the best performance and reliability, with support and customer services which give Zenit’s solutions a great added value.
