Patent number: 7118354Abstract: A submersible pump-motor assembly for use in dispensing petroleum from petroleum storage tanks. The pump-motor assembly of the present invention enhances the performance characteristics of the pump-motor assembly by providing greater flow area around the motor stator while maintaining the alignment of the assembly's critical pump components. Such enhanced pump performance characteristics provide the petroleum dispensing station manager using such pump-motor assemblies with greater flow rates per dispenser or, when maximum flow rates are capped, potentially greater dispensing capacity.Type: GrantFiled: December 15, 2001Date of Patent: October 10, 2006Assignee: Fe Petro, Inc.Inventors: Donald P. Kenney, Donald A. Gibson, Randy E. Craig

Patent number: 6070760Abstract: A pumping system for use in a fuel service station including one or more fuel dispensers, a fuel storage tank and conduits connecting the fuel dispensers with the tank. The pumping system comprises a variable speed pump-motor assembly for pumping fuel from the storage tank to the conduit and the dispensers, and a control connected to the pump-motor assembly for holding the fuel pressure in a preset range. Preferably the range is that required for efficient operation of a vapor recovery system, or other requirement by the EPA or by another agency, or by a service station operator. The control includes sensors which respond to the pressure in the conduits leading to the fuel dispensers. The sensors may comprise, for example, a pressure sensor in the conduit, or they may comprise power consumption sensors connected to the electrical power supply for the variable speed pump-motor assembly.Type: GrantFiled: May 4, 1999Date of Patent: June 6, 2000Assignee: FE Petro Inc.Inventors: Donald P. Kenney, David M. Triezenberg

Patent number: 5762104Abstract: This disclosure relates to a system for pumping a liquid from a storage tank, through a pipe and out of a valve of a liquid dispenser. The apparatus comprises a manifold housing having a main flow passage formed therein, a check valve mounted in said main flow passage and enabling liquid to flow from the storage tank to the liquid dispenser, and a manually-operated pressure relief mechanism around the check valve. The mechanism comprises a bypass flow passage formed in the housing in parallel with the check valve, and a stopper which normally closes the bypass flow passage. To relieve the liquid pressure, the stopper is manually moved to a relief position where it is removed from the bypass flow passage, thereby enabling the liquid to flow around the check valve. To resume normal operation, the stopper is returned to its normal position where it blocks the bypass flow passage. The stopper is movably mounted in a bore in the housing, and the bore extends to an opening at the exterior surface of the housing.Type: GrantFiled: October 10, 1995Date of Patent: June 9, 1998Assignee: Fe Petro Inc.Inventors: Brian C. Green, Leon R. Schuster

Patent number: 5577895Abstract: This disclosure relates to a variable length pipe assembly for connection between a pump-motor unit and a manifold. The assembly is particularly useful in a gasoline dispensing system of a service or filling station. The assembly comprises an inner pair of pipes and an outer pair of pipes. The pipes of the inner pair have telescoped portions and outer ends that are connectable to the pump-motor unit and the manifold. The pipes of the outer pair also have telescoped portions and outer ends that are connectable to the pump-motor unit and the manifold. The inner pair is mounted within the outer pair, a first passage being formed within the inner pair and a second passage being formed by the annular space between the inner pair and the outer pair. A seal is provided between the telescoped portions of the inner pair and another seal is provided between the telescoped portions of the outer pair, and a clamp is provided for securing together the telescoped portions of the outer pair.Type: GrantFiled: February 24, 1995Date of Patent: November 26, 1996Assignee: FE Petro Inc.Inventors: Charles C.
