sera pump technology for perfectly treated cooling water.
At the end of 2010, sera delivered 19 selectable Profibus pumps of the types C409.2 and C410.2 to a nuclear power plant in southern Germany. After on-site consultation by a sera engineer and as a result of the proposal, the operator of the plant decided in favour of the proven dosing pumps from sera without hesitation. This decision was influenced by the good experience the company had had with previous sera pumps in the plant that had been in operation for 30 years without a problem. Modernisation was required because a new process control system (PCS) had been installed at the nuclear power plant and new selections via Profibus had become necessary for the pumps.
The sera dosing pumps are used for the treatment of cooling water for the towers, which is taken from an adjacent river. The suspended matter in the river water is treated by adding a flocculating agent along with stabilisers to ensure the correct pH and required hardness.
State-of-the-art pump technology for maximum operational reliability
The operator requested that each unit should be supported by a redundant pump to ensure uninterrupted operation in the event of a failure. All sera pumps are equipped with selection via Profibus as well as a frequency converter for speed control.
Furthermore, it was important for the operator that in the event of a failure of the process control system (PCS), each pump could be operated individually and manually. This is guaranteed by an optimised manual stroke adjustment as well as a separate Profibus cable for each pump. Thus, there is no ‘Profibus loop’ and in the event of a failure of the PCS the pumps can be operated manually without problems. In addition, the proven diaphragm condition monitoring, installed at each pump, significantly contributes to the reliability of the systems.
Tailored customer requirements
Since the Profibus dosing pumps were installed and commissioned on site by a sera installer, they have been working to the full satisfaction of the operator since June 2010.
Thanks to the proven sera ‘Plug and Dose’ principle and everything from a single source service, a custom-tailored solution was delivered to the customer guaranteed for many years of trouble-free operation.
