Abstract
Embodiments of the invention provide a method of controlling a pump. The method includes sensing a pressure in the pump and entering a low-flow mode when the sensed pressure in the pump is greater than a low pressure threshold. The method also includes reducing power to the pump when the sensed pressure is greater than a shut-off pressure during the low-flow mode and there is flow through the pump until the sensed pressure is less than the shut-off pressure. The method further includes turning the pump off when in the low-flow mode the sensed pressure is greater than the shut-off pressure and there is no flow through the pump.
