An operator of a large freight ferry selected Hydra-Cell seal-less pumps for three different applications on its vessel. This would not be unusual because Hydra-Cell is offered in a wide range of models, capacities, and materials of construction. The operator, however, requested that all three pumps be built to the same specifications as to allow maximum on-board versatility. In addition, the pumps were individually tested, inspected and certified by DNV, one of the world’s leading certification organizations.
