  • Publication number: 20140064985
    Abstract: Embodiments of the invention provide a pumping system for at least one aquatic application. The pumping system includes a pump, a motor coupled to the pump, and a controller in communication with the motor. The controller determines an actual power consumption of the motor and compares the actual power consumption to a reference power consumption. The controller also determines that the pump is in an unprimed condition if the actual power consumption is less than the reference power consumption and that the pump is in a primed condition if the actual power consumption is at least equal to the reference power consumption.

  • Publication number: 20140027359
    Abstract: A pumping system for moving water of a swimming pool includes a water pump, a variable speed motor, and a filter arrangement in fluid communication with the pump. The pumping system can also include means for determining a load value indicative of an unclogged filter that permits movement of water through the filter arrangement, means for determining a load value indicative of a clogged filter that inhibits movement of water through the filter arrangement, and means for determining a performance value of the pumping system. The pumping system also includes means for determining a relative loading value of the filter arrangement, means for displaying the relative loading value, and means for controlling the motor in response to the relative loading value. In one example, the load values and performance value can include flow pressure values. A method of moving water of a swimming pool is also disclosed.

  • Patent number: 8602743
    Abstract: Embodiments of the invention provide a method of operating a safety vacuum release system (SVRS) with a controller for a pump including a motor. The method can include measuring an actual power consumption of the motor necessary to pump water and overcome losses. The method can include triggering the SVRS when a dynamic suction blockage is identified in order to shut down the pump substantially immediately. The SVRS can also be triggered when a dead head condition is identified based on the actual power consumption.

  • Patent number: 8602745
    Abstract: Embodiments of the invention provide a system including a pump, a motor, and a controller. The controller establishes a baseline value of power consumption during a deadhead condition, increases a counter when a current value decreases below the baseline value, and determines a deadhead condition when the counter exceeds a limit. The controller also compares a current value to an immediately previous power consumption value to determine an entrapment condition indicated by a sudden decrease in power consumption.

    Abstract: The present invention provides a pumping system for moving water of a swimming pool, including a water pump and a variable speed motor. In one example, a target volume amount of water and an operational time period is provided, and the operational time period is altered based upon a volume of water moved. In another example, operation of the motor is altered based upon the volume of water moved. In addition or alternatively, a target flow rate of water to be moved by the water pump is determined based upon the target volume amount and a time period. In addition or alternatively, a plurality of operations are performed on the water, and a total volume of water moved by the pump is determined. In addition or alternatively, an optimized flow rate value is determined based upon power consumption.

  • Publication number: 20120152866
    Abstract: Embodiments of the invention provide a pump and filter system and method. The system includes a housing with a housing cavity and a filter cartridge, and a pump positioned in the housing cavity. The filter cartridge splits the housing cavity into a filtered region and an unfiltered region and the pump is located in the filtered region. The method includes operating the pump to pull fluid through a housing inlet into the unfiltered region, to pull fluid across the filter cartridge into the filtered region via suction pressure of the pump, and to force the fluid through the pump to a housing outlet.

  • Publication number: 20120063921
    Abstract: A pumping system includes a pump for moving water. In one aspect, this is in connection with performance of an operation. The system includes a variable speed motor operatively connected to drive the pump. A value indicative of flow rate of water is determined and the motor is controlled to adjust the flow rate indicative value toward a constant. A value indicative of flow pressure is determined and the motor is controlled to adjust the flow pressure indicative value toward a constant. A selection is made between flow rate control and flow pressure control. In another aspect, the pump is controlled to perform a first operation, and is operated to perform a second water operation. Control of operation of the pump to perform the first water operation is altered in response to operation of the pump to perform the second operation.

  • Publication number: 20110091329
    Abstract: A pumping system for moving water of a swimming pool includes a water pump, a variable speed motor, and an arrangement for controlling the variable speed motor. The pumping system further includes an auxiliary device operably connected to the arrangement for controlling, and an arrangement for providing two-way communication between the arrangement for controlling and the auxiliary device. The arrangement for controlling is capable of receiving a parameter from the auxiliary device through the arrangement for providing two-way communication. In one example, the arrangement for controlling is capable of independently controlling the variable speed motor without receipt of a parameter from the auxiliary device. In addition or alternatively, the arrangement for controlling is operable to selectively alter operation of the motor based upon the parameter.
