    Abstract: A vertical pump features stationary bowl assembly, a rotating power transmission shaft, impellers and bottom wear-ring bearings. The stationary bowl assembly includes bowls, each bowl having a respective bowl bottom inside surface. The rotating power transmission shaft is configured to extend through the stationary bowl assembly. The impellers are arranged on the rotating power transmission shaft to rotate and draw material through the stationary bowl assembly, each impeller having a respective impeller bottom outside surface. Each bottom wear-ring bearing is arranged between the respective impeller bottom outside surface of each impeller and the respective bowl bottom inside surface of each bowl, made from a non-galling bearing material, and configured to maintain the alignment of the rotating power transmission shaft in relation to the stationary bowl assembly.

    Abstract: A coalescing removal separator includes a separator tank having a separator input configured to receive a fluid flowing through a system having entrained gasses and solid particles, having a tank wall configured to form a volume/chamber inside the separator tank to process the fluid, and having a separator output configured to provide processed fluid that is free of at least some of the entrained gasses and solid particles; and a coalescing media arranged in the volume/chamber of the separator tank, the coalescing media having at least one helically wound brush with a stem and intertwined bristles substantially filling the volume/chamber of the separator tank and being configured to enable the at least some of the entrained gasses and solid particles to come out of the fluid.

    Abstract: A condition monitoring device for monitoring machinery includes a combination of on-board sensors and a condition monitoring module. The on-board sensors include modules for non-contact temperature, magnetic flux and 3-axis vibration sensing of the machinery. The condition monitoring module provides a condition monitoring signal containing information about an operating condition of the machinery, based upon a data synthesis condition monitoring technique that synthesizes non-contact temperature, magnetic flux and 3-axis vibration sensed data received from the combination of on-board sensors, determines a current operating condition of the machinery, and compares the current operating condition and the baseline operating condition of the machinery.

    Abstract: A balance or flow limiting valve features a valve body/member having a flow rate indicator/scale containing setting having printed flow rates calibrated in units of measure in volume per time increment between a minimum flow rate position (MIN) and a maximum flow rate position (MAX); and a knob/handle having a position indicator and being moveable to any continuous position on the flow rate indicator/scale between MIN and MAX in response to a user applied force, where the relationship between the flow rate indicator/scale and the position indicator is based on calibrated flow characteristics of the balance or flow limiting valve. The user can set an exact desired flow rate in one operation by moving the knob/handle to a desired position between MIN and MAX without consulting a printed flow curve or balance calculator to determine the desired exact flow rate.

    Abstract: Apparatus features a controller having a signal processor or processing module configured to: receive signaling containing information about a power profile that is specific to a pumping system having N parallel pumps and based upon data related to one or more of pumping system power, losses and wire-to-water efficiency in real time for the N parallel pumps configured to run in the pumping system to generate a head H and a flow F with an efficiency E, and at least one calculation/prediction of at least one corresponding efficiency of at least one combination/number of N−1 and/or N+1 parallel pumps to achieve a corresponding/same head H and flow F with a corresponding efficiency; and determine corresponding signaling containing information to control the operation of the pumping system that depends on a comparison of the efficiency E and the at least one corresponding efficiency, based upon the signaling received, including staging/destaging a pump to or from the pumping system.

    Abstract: Apparatus is provided featuring a signal processor or processing module configured to receive signaling containing information about a pump no flow idle (NFI) state when the pump is running at a pump idle speed; and determine corresponding signaling containing information about whether the pump should remain in a no flow shutdown (NFSD) state or the pump NFI state, based upon the signaling received. The signal processor or processing module is configured to provide the corresponding signaling containing information about whether the pump should remain in the NFSD state or the NFI state.

    Abstract: A spiral heat exchanger features: a cold fluid inlet manifold, a hot fluid inlet manifold and at least one spiral fluid pathway. The cold fluid inlet manifold receives cold fluid and provide cold inlet manifold fluid. The hot fluid inlet manifold receives hot fluid and provide hot inlet manifold fluid. The at least one spiral fluid pathway includes cold spiral pathways configured to receive the cold inlet manifold fluid and provide cold spiral fluid pathway fluid, and hot spiral pathways configured to receive the hot inlet manifold fluid and provide hot spiral fluid pathway fluid. The cold spiral pathways and the hot spiral pathways are configured in relation to one another to exchange heat between the cold spiral pathway fluid and the hot spiral pathway fluid so that the hot spiral fluid pathway fluid warms the cold spiral fluid pathway fluid, and vice versa.
