    摘要: A pump (100) has an inlet (28), a first outlet (30) and a second outlet arrangement. The pump (100) is arranged so that when operated in a body of water (104), water from that body of water (104) is pumped thought the first outlet to a remote location. Additionally liquid is delivered to the second outlet system (102) which subsequently flows out from the second outlet system (102) back into the body of water (104) to create a flow of the liquid back into the body of water 104 and away from the pump (100). The liquid can be water from the body of water (104). In this instance a portion of the water at the first outlet can be diverted to the second outlet arrangement. But alternately liquid can be sourced externally from the body of water (104).
