Abstract: A sump pump system may detect and utilize motion or acceleration of water in sump basins when implementing control of sump pumps. To detect the motion or acceleration, the sump pump system may utilize a sensor that is configured to detect motion or acceleration, such as an accelerometer or gyroscope. The sump pump system may identify a water level in a sump basin based on the detected motion or acceleration, which may be compared to a reading or expected signal from the sump pump system's “typical” sensor (e.g., float switch) that is used to detect one or more water levels. In this manner, the sump pump system may detect a malfunctioning level sensor that is used by the pump to detect high-water and low-water marks at which the sump pump activates and deactivates, respectively.

Abstract: Systems and methods for automatically adapting operation of an electric drive system for an electric submersible pump (ESP). A control system for an electric drive receives live measurements of operating conditions of the ESP as the ESP is operating. The control system calculates adjustments to settings of the electric drive which generates output power that drives the ESP, where the adjustments are calculated based at least in part on the live measurements, and without user intervention. The control system thereby automatically controls the drive to modify the output power provided to the ESP, which in turn controls the operation of the ESP. The adjustments may increase the stability of the ESP's operation, improve the performance of the ESP, and adapt the ESP's operation to changing well conditions.

Abstract: A pump arrangement for conveying a liquid, in particular for conveying waste water or service water, includes a pump housing and an impeller rotatably arranged in the pump housing about a rotation axis for conveying the liquid. At least one sensor, in particular a 3D sensor, is present for detecting a surface of the impeller to sense an extent of build-up on the impeller. The at least one sensor is arranged on and/or in the pump housing.

Abstract: The invention relates to a method of controlling a power limit (P) of a circulating pump (1) comprising a critical component (4) and a first temperature sensor (5) arranged and configured to measure the temperature of the critical component. The first temperature sensor may be arranged on top of, below, integrated with, or in the vicinity of the critical component. The method comprises monitoring the temperature (T) of the critical component by use of the first temperature sensor and using an output signal (6) from the first temperature sensor as a first temperature input signal (7) to a controller (8). By use of the controller and based on the first temperature input signal, the power limit of the circulating pump is controlled in accordance with a performance derating curve for the circulating pump. The invention further relates to a system (3) for controlling a power limit of a circulating pump by use of such a method.

Abstract: Disclosed herein are a pump and a method for controlling the pump for discharging a fluid. The pump may have an impeller configured to move fluid through the pump in a common direction regardless of which way the impeller rotates, an electric motor configured to drive the impeller, and a controller configured to detect potential failure of the impeller to rotate, and, in response to detection of the potential failure, reverse polarity of current to the electric motor to reverse rotation of the impeller.

Abstract: A controllable pump system can include an inlet line and a pressure controlled pump connected to the inlet line to receive input flow. The pressure controlled pump can have a pressure controlled pump state configured to control a pump output to an output line connected to the pressure controlled pump. The system can include a slew pump connected to the inlet line and configured to output a slew pump pressure, and a slew pressure valve connected to the input line and to a second line and configured to output a control pressure to the pressure controlled pump. The second line can be configured to be in fluid communication with at least the slew pump such that the slew pressure valve can receive the slew pump pressure.
