Publication number: 20130129536Abstract: Embodiments of the invention provide a pumping system and method including a flow locking feature. A pump controller includes a user interface configured to initially receive and set a plurality of programmed flow rate settings, a maximum locked flow rate, and a minimum locked flow rate. The pump controller is also configured to disable resetting of the maximum flow rate and the minimum flow rate once they are initially received and set and to allow resetting of the plurality of programmed flow rate settings throughout operation of the pumping system. The pump controller is further configured to operate a pump motor in order to maintain a first flow rate set by one of the plurality of programmed flow rate settings as long as the first flow rate is between the minimum locked flow rate and the maximum locked flow rate.Type: ApplicationFiled: November 1, 2012Publication date: May 23, 2013Inventors: Ronald B.

Publication number: 20120063921Abstract: 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.Type: ApplicationFiled: September 12, 2011Publication date: March 15, 2012Inventors: Robert W.

Publication number: 20090136363Abstract: Embodiments of the disclosure provide a booster pump to pressurize fluid for use by a pool cleaner in a pool or spa. The booster pump includes a front housing having an inlet, a plurality of diffuser units positioned in the front housing, and a motor housing detachably coupled to the front housing and having an outlet. A submersible motor positioned in the motor housing is operatively coupled to the diffuser units. A space is defined between an outer surface of the motor and an interior surface of the motor housing. A self-contained fluid flow path is formed from the inlet, through the diffuser units, and through the space to the outlet. As the fluid passes over the motor, the motor can be cooled and acoustic output of the booster pump can be dampened. The booster pump can be constructed of plastic for applications in the pool and spa industry.Type: ApplicationFiled: October 23, 2008Publication date: May 28, 2009Inventors: Robert W.

Patent number: 5878773Abstract: A Flow control valve for a pump suction line permitting flow from an alternate source in the event of partial or complete blockage of a main source. The valve includes a valve housing having a main inlet port at one end, on auxiliary inlet port at its other end and a suction port between the inlet ports. Flow responsive valves are provided at the inlet ports and the valves are spring biased by springs which allow normal flow through the main inlet port. If the main inlet port is blocked the auxiliary port is opened. A flap valve is actuated by flow through the auxiliary port to close the auxiliary port and to create hydrostatic pressure between the blockage and the main inlet port to thereby dislodge the blockage.Type: GrantFiled: September 15, 1997Date of Patent: March 9, 1999Assignee: Essef CorporationInventor: Ronald B.

Patent number: 5574334Abstract: A conductive sleeve is located around each of the filament supports of an incandescent lamp enclosed in a glass bulb. The sleeve is spaced from the support by an insulating spacer. The sleeve is connected to a ground so that if the bulb breaks liquid flowing into the bulb creates a conducting path between the filament supports and the ground. The sleeve has a generally hollow, cylindrical shape spaced and is positioned around the support.Type: GrantFiled: March 13, 1995Date of Patent: November 12, 1996Assignee: Essef CorporationInventor: Ronald B.
