Some embodiments of the invention provide a pumping system for at least one aquatic application. The pumping system includes a pump, a motor coupled to the pump, a user interface associated with the pump designed to receive input instructions from a user, and a controller in communication with the motor. The controller determines a power parameter associated with the motor and compares the power parameter to a predetermined threshold value. The controller triggers a safety vacuum release system based on the comparison of the power parameter and the threshold value.

A pump arrangement, in particular in a coating installation for the coating of components, such as a painting installation for the painting of motor vehicle body components, is provided. The pump arrangement includes a plurality of adjustable pumps for delivering a coating agent, e.g. for delivering a sealing agent for the sealing of weld seams on a motor vehicle body component. The pumps are connected in parallel such that the pumps extract the coating agent for delivery from a common inlet line and deliver said coating agent into a common outlet line. The arrangement further includes a control device for the open-loop or closed-loop control of one fluid variable at the outlet of the individual pumps, respectively, wherein the control device actuates the individual pumps individually, and/or a monitoring unit, which switches the pumps on and off non-simultaneously.

Technologies are generally described for a vibration band alarm configuration tool to facilitate efficient and reliable setting configuration by displaying data and analyses pertaining to the data produced by a vibration transducer attached to a rotating machine and thereby reduces needed knowledge of machinery and vibration analysis. Various parameters and data sets may be calculated from the time domain waveform and displayed with collected data to simplify the recognition of features that represent system components and anomalies pertinent to the health of the rotating machine such as a pump assembly. Manually manipulatable controls on a graphic user interface may allow a user to set alarm bands and thresholds. Suggestions based on physical and/or statistical models, as well as, machine-specific historic data may be presented as well.

A method of controlling monitoring of a vacuum system, the vacuum system, and the monitoring control system are disclosed. The method comprises: selecting at least one of a plurality of processes for monitoring the vacuum system from a data store storing the plurality of processes. Executing the at least one selected process Wherein one of the at least one selected processes comprises a process for monitoring a parameter of the vacuum system and for responding to changes in the parameter to trigger at least one of: execution of a further one of the plurality of processes; output of an alarm or notification signal; and output of a control signal for controlling operation of at least one component of the vacuum system.

A display system is provided that includes: a rotary machine device including a rotary machine and a drive machine causing the rotary machine to rotate; a display device capable of displaying a state of the rotary machine device; a detection section acquiring plural state quantities indicating the state of the rotary machine device; and a display control section displaying a chart on the display device on the basis of the plural state quantities acquired by the detection section, the chart being configured as a multidimensional chart in which the plural state quantities of the rotary machine device at specific time are plotted and the plural state quantities are set as values, each of which corresponds to each axis.

A liquid leak detector for a pump is described. The liquid leak detector is mountable on a pump to detect leaked fluid coming from the pump. The leak detector includes a buffer tube positioned on the pump to collect a leaked fluid from the pump and a sensor positioned on the buffer tube to detect the level of leaked fluid in the buffer tube and to generate a signal when the leaked fluid reaches a maximum fluid level. A purge line on the buffer tube removes leaked drive fluid from the buffer tube once the leaked drive fluid reaches a maximum level. Logic connected to the sensor receives the signal from the detector and generates an alarm.
