    Abstract: A switch assembly features an automatic switch and an electronic circuit board. The automatic switch has a common contact and a normally open switch contact to short when a boiler has sufficient water, and has the common contact and a normally closed switch contact to short when the boiler has a low water level. The electronic circuit board has a signal processor, a reset switch, and a low water status LED for providing a status indication of a low water condition that remains ON even if the water level has risen unless the reset switch is reset. The signal processor couples to the common contact, the normally closed switch contact and the normally open switch contact, senses signaling containing the status of the common contact, the normally closed switch contact and the normally open switch contact, provides corresponding signaling to turn ON the low water status LED when the water level is low, and responds to a reset switch signal and turn OFF the low water status LED.

    Abstract: The present invention provides for a device or feature that incorporates a technique or means for flow measurement in a fluid flow system. By way of example, a contoured insert may be specifically calibrated to the pipe line size to ensure the desired accuracy of the flow measurement, irrespective of pipe length between the device and other fluid system components that would negatively influence other flow rate measurement devices. This in turn reduces the total number of components needed in a system.

    Abstract: A pump features a trimmed impeller having a trimmed impeller diameter that is less than a standard full-sized diameter of a standard full-sized impeller for a standard full-sized casing, and having a circumferential outer edge; and a modified standard full-sized casing having dimensions corresponding to the standard full-sized casing and configured to house the trimmed impeller for pumping a fluid, having an outer peripheral wall, and having an inner annular volute portion between the circumferential outer edge of the trimmed impeller and the outer peripheral wall configured with a volume of material deposited using an additive manufacturing process so as to fill in vacant space otherwise caused by the trimmed impeller diameter being less than the standard full-sized impeller diameter. The additive manufacturing process is a directed energy deposition.

    Abstract: A vertical in-line split couple pump includes a motor shaft having a motor shaft collar; a pump shaft having a pump shaft collar with a pump shaft angled collar surface oblique to an axis of the motor and pump shafts; and a coupler having coupler halves that attach together, that have a couple groove to receive the motor shaft collar, and have a couple angled groove to receive the pump shaft collar. The couple angled groove has a couple angled groove surface oblique to the axis. The coupler halves respond to a force that moves them together to couple the pump and motor shaft together, moves the pump shaft angled collar surface in relation to the couple angled groove surface, causing the pump shaft to move upwardly towards the motor shaft along the axis, to provide a way to jack-up and recouple the pump shaft and any impeller attached thereto by one mechanic.

    Abstract: A pump features a two-part axial flow shaft having a static inner shaft portion and a rotating outer shaft portion; the static inner shaft portion having static diffuser vanes, and also having two shaft ends configured to affix to a frame of a pump so the static inner shaft portion does not rotate; and the rotating outer shaft portion having an outer portion configured to affix to a rotor of the pump to rotate the rotating outer shaft portion, also having rotating impeller vanes configured inside and coupled to the outer portion to move the fluid axially along the two-part axial flow shaft as the rotating outer shaft portion axially rotates in relation to the static inner shaft portion.

    Abstract: A pump controller features a signal processor configured to respond to signaling containing information about three corresponding discrete arrays with respect to a discrete motor speed for each system position at a motor speed derived from 3D discrete distribution surfaces of motor power, pump differential pressure and flow rate by respective numerical interpolations; and determine corresponding signaling containing information to control a pump, or pumps in a system of pumps, or a system of pumps based upon a corresponding pump differential pressure and flow rate at the motor speed for a corresponding power reading value determined using a numerical interpolation of the three corresponding discrete arrays, the signaling received. The signal processor is configured to provide the corresponding signaling as control signaling to control the pump, or the pumps in the system of pumps, or the system of pumps.
