Abstract: A vortex prevention device is capable of preventing creation of air entrained vortex and also provides a double suction vertical pump having such a vortex prevention device. The vortex prevention device is used in combination with the double suction vertical pump which is installed in an open channel and has an upper suction opening and a lower suction opening. The vortex prevention device includes a plate member as a vortex prevention structure arranged above the upper suction opening. The plate member is arranged away from the upper suction opening such that a passage is formed between the plate member and the upper suction opening.
