Abstract: An air operated diaphragm pump is provided a housing having an orifice formed therein; a gas passageway configured to provide gas through the air operated diaphragm pump in order to pump syrup through the air operated diaphragm pump; a syrup passageway configured to provide the syrup through the air operated diaphragm pump when the gas is passed though the gas passageway, part of the syrup passageway configured in fluidic communication with the orifice of the housing with an inside pressure greater than an external pressure of the outside atmosphere when the syrup is provided through the air operate diaphragm pump; and an indicator arrangement configured or arranged in the orifice of the housing to communicate with the syrup passageway, and to respond or activate when a vacuum force exceeds a predetermined level and provide a visual indication when the syrup is no longer provided through the air operated diaphragm pump.

Abstract: An air operated diaphragm pump is provided featuring a housing, a fluid passageway and an indicator arrangement. The housing is configured with an orifice. The fluid passageway responses to a vacuum force and provides fluid, such as syrup from a bag or container to a beverage dispenser, through the air operated diaphragm pump via the fluid passageway, and is configured with a suction plenum or channel formed by an enclosed space with an inside pressure that is greater than an external pressure of the outside atmosphere when the fluid is being provided through the air operated diaphragm pump via the fluid passageway. The suction plenum or channel is configured to be in fluidic communication with the orifice of the housing. The indicator arrangement is configured in relation to the orifice of the housing to communicate with the suction plenum or channel, and also configured to respond or activate when the vacuum force exceeds a predetermined level and provide a visual indication when the fluid is no longer being provided through the air operated diaphragm pump via the fluid passageway.
