A controller for controlling operating parameters associated with fluid flow, speed or pressure for a centrifugal pump for pumping fluid, wherein at least one sensor is coupled to the pump for generating a signal indicative of a sensed operating condition. The controller comprises a storage device for storing data indicative of at least one operating condition and a processor in communication with the sensor and operative to perform an algorithm utilizing the at least one sensor signal and the stored data indicative of the at least one operating condition to generate a control signal, wherein the control signal includes a correction factor between 0. 1 and 1. 0 that is applied to the pump controlling algorithm in order to prevent overcorrection.

A method and system for determining pump cavitation is disclosed. In accordance with the principle of the invention, changes in dynamic fluid pressure within a pump are monitored and compared to a determined cavitation alarm pressure. The determined cavitation pressure is determined as a known percentage of a known non-cavitation pressure. Fluid cavitation is determined when the change in dynamic fluid pressure falls below the determined cavitation alarm pressure. In a further aspect of the invention, a remaining mechanical seal operational life can be determined by maintaining a total time of fluid cavitation and reducing the expected life by the known operational time of the pump and the time the pump is in cavitation.

A method for determining whether a centrifugal pump is degraded as operating outside of acceptable operating limits and includes the steps of determining a motor torque/TDH relationship over a range of speeds for minimum and maximum flow rates and at least at two other intermediate flow rates, sensing and measuring at least another pump value selected from a differential pressure across the pump, a pump discharge pressure or pump flow, to provide an output pump value and comparing said value with said determined relationship values to provide an indication as to whether said pump has degraded.

A method and system for dynamically determining a vapor pressure of a fluid passing through a pumping system by diverting a portion of the fluid from the pumping system into a chamber, isolating the diverted fluid from the pumping system, evacuating the chamber and measuring the vapor pressure of the isolated fluid. In another aspect of the invention, a temperature compensation device is included in the chamber to alter the chamber fluid temperature to insure that the chamber fluid temperature is substantially the same as the fluid in the pumping system.

A method is provided of identifying a rotating bearing defect featuring the steps of measuring the vibration of the rotating bearing to obtain a waveform signal; filtering the waveform signal to remove unwanted signal frequencies; enveloping the filtered waveform signal to obtain an enveloped low frequency time waveform; and synchronizing the enveloped low frequency time waveform to the running speed of the rotating bearing in such a way to preserve the phase relationship between the tachometer pulse and bearing defect to obtain a time synchronized waveform. The method may include the step of measuring the rotational speed of the rotating bearing; and the step of measuring the rotational speed of the rotating bearing comprises measuring the rotational speed of the rotating bearing with a tachometer.

A method for determining whether a centrifugal pump is operating within its normal flow operating range includes the steps: of determining a motor torque/TDH relationship over a range of speeds for a minimum flow rate in order to obtain a minimum flow operating range for the centrifugal pump; determining a motor torque/TDH relationship over a range of speeds for a maximum flow rate in order to obtain a maximum flow operating range for the centrifugal pump; determining the actual operating motor torque and TDH of the centrifugal pump at a given operating point; and determining whether the actual operating motor torque and TDH of the centrifugal pump fall within the minimum flow and maximum flow operating ranges of the centrifugal pump.
