A hydraulic pumping system for pumping a flow of aqueous liquid, for HVAC and potable water systems, through a plurality of hydraulic pump assemblies and mating branching feeder pipes extending between a main inlet pipe and a main outlet pipe for outputting the total flow of water, each of said pump assemblies in operative association with a mating feeder pipe to control aqueous liquid flow through said associated feeder pipe, wherein each of the hydraulic pump assemblies comprises an electric motor, mechanically coupled to a centrifugal pump and a variable frequency drive (VFD) electrically coupled to the motor. A controller is electrically coupled via a communication channel to the VFD of each of the hydraulic pump assemblies, the controller comprising a programmable device programmed to control the speed of each of the motors via the connected VFD. The controller receives data from each of the VFDs, said data comprising the amount of electrical power consumed by the VFD, the speed of the associated motor, an estimation of aqueous liquid flow, and an estimation of head, and calculates the total aqueous liquid flow through the plurality of pump assemblies, and the total system head, so that the controller can vary the speed of each VFD to adjust the total system with respect to the desired system head.

The flow path opening/closing portion replacement device comprises a first enclosing portion having a first opening and a shutter, and enclosing, in a state where the shutter has closed the first opening, an end portion of a converging pipe through which a fluid passes and a valve which is attached to the end portion; a second enclosing portion having a detachable member enabling the valve to be detached and a second opening which can be contiguous with the first opening and enabling removal/insertion of the detachable member, and enclosing the valve together with the first enclosing portion in a contiguous opening state in which the first opening and the second opening are contiguous, wherein, in a state where the second enclosing portion has enclosed the valve together with the first enclosing portion in the contiguous opening state, the valve can be replaced by the detachable member.

A pump system for liquid media includes at least one pump having a suction side and a delivery side, a control unit connected to the at least one pump, and at least two controllable valves connected on one side thereof to the suction side. The valves are controlled by the control unit connected thereto, such that each valve only allows passage of medium from a first source or second source connectable to their respective other valve sides. The pump system also includes at least one level sensor connected to the control unit, which level sensor is positioned at least near the source where, in the case of a critical level being exceeded, medium must be pumped away.

A system and method for operating a low-yield well. The method starts with a pressure transducer telling a control box that a storage tank is low on water. The controller then activates the well pump, the water then flows up a pipe past a pressure transducer showing the back pressure, through a regulator and into the storage tank. The controller is constantly monitoring the tank level and the back-pressure level to indicate when to turn off the well to either stop from over filling the storage tank, or over pumping the well. The controller makes adjustments dependent on the back pressure (which indicates the level of water left in the well) and determines how long to withdraw water and how long to wait until the water can be withdrawn again. The system prevents pumping the well dry, and keeps the pump and well in good operating condition.
