Bungartz presented its centrifugal pumps twice at the Chemtech fair for chemical and process industries in India.
Within the accompanying congress programme, Michael Wolf, regional director Asia-Pacific, presented the centrifugal pumps to visitors. A functional model of the self-regulating centrifugal pump of the V-AN range was presented at the Bungartz fair booth. The MPCVAN could be observed at the delivery of gas-laden liquids or being under vacuum.
Under the heading ‘self-regulating centrifugal pumps for a higher plant reliability’, Michael Wolf presented on pump failures and faults to the interruption of the production. Using the example of a self-regulating, dry-running pump of type V-AN, he explained the application of a safe pumping technology enabling a simultaneous reduction of the overall operating costs. “For almost 10 years, this pump was running at a large internationally operating chemical company”, Wolf said. “Without any additional intervention from the outside, it delivered in a self-regulating manner and depending on a intake liquid level – as do all pumps of the V-AN range working cavitation-free, since the NPSHR is less than 0.1 m.” For the operation of the pump, a minimum static height is sufficient. Therefore, the construction of a pit is not required.
Wolf also spoke about the newest developments at Bungartz, whose real time demonstration was shown for visitors at the booth:
There, visitors were able to put the centrifugal pump MPCVAN into operation using a functional model. The MPCVAN of the V-AN range self-regulating pumps has been designed for the delivery of extreme media. The magnetically coupled vertical pump is hermetically sealed and secured against operating errors. “Even here, the sealing concept is based on the complete hydrodynamic relief of the bearing and sealing unit. Back vanes and a gas barrier prevent liquids and product vapours from penetrating into the bearing unit”, said Wolf.
