Abstract: There is disclosed a maintenance reminder system for a pump. The system of the invention is coupled to the pump or the control system for the pump and determines the volume of fluid pumped by the pump. In the preferred embodiment, a piston pump is used and piston strokes are counted and converted to total volume of liquid pumped. The computer of the system maintains a database for each maintenance item containing the threshold value for each item and the total volume pumped since the last maintenance. When the total volume exceeds the threshold, a maintenance reminder is displayed and the user may display information from the database as to which item needs service. The computer updates the appropriate fields of the database after the service is performed.

Abstract: A pump has a signal processor, including one forming part of a printed circuit board assembly, that receives signaling containing information about a voltage supplied to a motor to run a particular pump model, and also containing information about whether a current draw of the pump is lower than a predetermined low current level or is higher than a predetermined high current level; and determines whether to shut off the pump after a predetermined time, based on the signaling received. The signal processor provides control signalling to shut off the pump after the predetermined time if the current draw of the pump is lower than the predetermined low current level or is higher than the predetermined high current level, where the predetermined low current level and the predetermined high current level depend on the voltage being supplied to the motor to run the particular pump model.

Abstract: A liquid pump control system for dry run avoidance and re-prime detection. Pump dry run conditions (such as an empty liquid source tank) can be detected with improved sensitivity by measuring pump cycle speed. Pump cycle speed is determined from sensors including pressure sensors, diaphragm end of stroke indicators, check valve movement sensors, and other techniques. The frequency content of the time-measured signal indicates pump cycle speed. When a dry run condition is detected from an increase in pump speed, a controller closes a valve to reduce pump cycle speed by reducing drive air pressure or by deadheading the pump liquid outlet. When the pump re-primes, the valve is opened, pump cycle speed increases, and pumping volume flow rate increases until a dry run condition is again encountered. Time delays can be introduced to delay shutting down or restarting the pump, for example to give a liquid source tank time to refill. The improved control sensitivity provides improved shut-down and re-start performance, reducing wear on the pump and reducing wasted drive air and energy consumption. The liquid pump control system can be integrated into the pump system, added on to existing pump systems, or located remotely from the pump itself.

Abstract translation: 一种用于干运行回避和重新检测的液体泵控制系统。 通过测量泵循环速度可以提高泵的干运行条件（如空液源罐），提高灵敏度。 泵循环速度由传感器确定，包括压力传感器，行程指示器的隔膜端，止回阀移动传感器和其他技术。 时间测量信号的频率含量表示泵循环速度。 当从泵速度的增加中检测到干运行状况时，控制器关闭阀门，通过减少驱动空气压力或者使泵液体出口处于死胡同状态来降低泵循环速度。 当泵重新启动时，阀打开，泵循环速度增加，并且泵送体积流量增加，直到再次遇到干运行状态。 可以引入时间延迟来延迟关闭或重新启动泵，例如给予液体储罐时间以重新填充。 改进的控制灵敏度提供了更好的关闭和重新启动性能，减少了泵上的磨损，并减少了浪费的驱动空气和能量消耗。 液体泵控制系统可以集成到泵系统中，添加到现有的泵系统上，或远离泵本身。
