German pump manufacturer Bungartz demonstrated functional models from its self-regulating centrifugal V-AN range and MPCVAN pump at the Chemtech World Expo.
Michael Wolf, regional director, Asia-Pacific at Bungartz presented both pumps under the heading Self-regulating centrifugal pumps for a higher plant reliability. He discussed pump failures, faults and the interruption of the production. Using the example of a self-regulating, dry-running pump from the V-AN range, he explained the application of a safe pumping technology to enable a reduction of overall operating costs.
The model he used had been running at a large international chemical company for almost 10 years. He noted that without any additional intervention it delivered in a self-regulating manner depending on a intake liquid level. He said that all pumps of the V-AN range work cavitation-free, since the NPSHR is less than 0.1m.
Visitors to the Bungartz booth were also able to operate the centrifugal pump MPCVAN using a functional model so that they could see the benefits. The intrinsically safe MPCVAN from 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.
