PUMP AND METHOD FOR CHANGING THE PUMPING CAPACITY OF A PUMP

摘要

A pump for fluids includes a pump housing, a power source enclosed within the housing, a drive shaft connected to the power source, at least one pump inlet arranged in the pump housing, a pump outlet arranged in the pump housing, a first impeller arranged within a first impeller chamber and rotated by the drive shaft, and a second impeller arranged within a second impeller chamber and rotated by the drive shaft. The pump is changeable between a first configuration in which the first and second impeller are arranged in parallel to provide a high pumping capacity, and a second configuration in which the first and second impeller are arranged in series to provide a pump with less pumping capacity.
