Abstract
A wet pump for pumping fish from a first fish receptacle to a second receptacle displaced from the first receptacle. The wet pump includes a wet pump tank into which the fish are initially pumped, a pump suction line connected to the side of the tank and communicating the tank with the first receptacle, a pump discharge line for pumping the fish from the tank, a pump system for initially creating a low pressure vacuum in the tank and for thereafter creating a high pressure in the tank, an inlet valve for opening the pump suction line when the pump creates the vacuum in the tank and for closing the pump suction line when the pump creates the high pressure in the tank, a discharge valve for closing the pump discharge line when the pump creates the vacuum and for opening the pump discharge line when the pump creates the high pressure, and a hood surrounding the inlet valve for preventing water from flowing proximate the inlet valve such that the fish do not interfere with the closing of the inlet valve when the pump is switched from the vacuum mode to the high pressure mode. When the pump creates the vacuum, the fish are suctioned through the pump suction line into the tank, and when the pump creates the high pressure, the fish are pumped from the tank through the discharge line into the second receptacle.
