Abstract: Systems and methods described herein provide a smart vacuum priming system for centrifugal pumps. The vacuum priming system includes a vacuum pump, a suction assembly, an electromagnetic clutch assembly, and a pressure sensor. The suction assembly provides fluid communication between the vacuum pump and a float box of the centrifugal pump. The electromagnetic clutch assembly selectively engages the vacuum pump, such that a drive shaft of the centrifugal pump also powers the vacuum pump when the clutch is on. The pressure sensor indicates when the centrifugal pump is in a primed state based on a discharge pressure of the centrifugal pump. When the pressure sensor indicates the main pump is in the primed state, the electromagnetic clutch decouples the vacuum pump from the drive shaft. When the pressure sensor indicates the main pump is not in the primed state, the electromagnetic clutch couples the vacuum pump to the drive shaft.

Abstract: A device includes a device input, an output connector configured to connect to a current loop, and current loop transmitter circuitry. The current loop transmitter circuitry receives, via the device input, an input from a dry contact switch, and translates a state of the dry contact switch to a current loop current. The current loop transmitter circuitry transmits the current loop current via the output connector through the current loop.

Abstract: A device, system, and method are provided for providing vibration data for rotating machinery. A sensor device is provided as a one-piece unit that is mechanically mounted to a pump. The sensor includes a vibration sensor, a processor, a wireless communications interface for exchanging data with a user device, and an internal battery.

The processor may combine the component vRMS values into a sample vRMS value, and send a final vRMS value, based on the sample vRMS value, to the user device via the wireless communication interface.

Abstract: Systems and methods described herein provide a configurable base plate for industrial pump configurations, including different combinations of pump, motor, and coupling types. Slotted motor adapters allow for axial adjustment of the motor position, and movable threaded mounting lugs lock in the motor position for ease of future maintenance, replacement, disassembly, and repeated reassembly. The mounting lugs are locked into place by affixing jackscrew lugs, which serve to both semi-permanently locate the motor mounting locations, and also provide a point to install a jackscrew used to finely adjust motor position and coupling alignment. A single adjustable coupling guard is compatible with a variety of pump, coupling, and motor configurations that fit on the base plate.

Abstract: Systems and methods are provided for remotely monitoring liquid lubricant levels for pump equipment. A system includes a reservoir to store lubricant and a lubrication gland to expose a shaft seal of the pump equipment to the lubricant. A feed line and a return line circulate the lubricant between the reservoir and the lubrication gland. A level sensor is configured to measure a fluid level in the reservoir. The level sensor uses a communication interface to transmit fluid level data a monitoring device mounted to the pump equipment. The monitoring device is configured to compare the fluid level data against stored alert thresholds and send, to a provider network, an alert signal when the fluid level data is below an alert threshold. If the fluid level data is not below an alert threshold, the monitoring device stores the fluid level data for periodic reporting.

Abstract: A centrifugal pump including a pump chamber, a wear plate, and a rotatable impeller is disclosed. The wear plate has a suction inlet. The pump chamber includes a high pressure region around the impeller within the pump chamber. The impeller's front face has portion located adjacent the wear plate to form a recirculation zone in fluid communication with the high pressure region. Another portion of the impeller's front face forms a small running clearance between it and a portion of the wear plate. That running clearance is interposed between the recirculation zone and the suction inlet. The wear plate includes plural deflector vanes projecting into the recirculation zone. A portion of the front face of the impeller includes plural pump-out vanes in the recirculation zone. The deflector vanes cooperate with the pump-out vanes to expel abrasive particles and prevent them from collecting and eroding the running clearance.

Abstract: A centrifugal pump with a cutter mechanism has a toothed cutter auger affixed to an impeller, and a toothed cutter stator affixed to the volute casing. The auger is a rotor cutter preferably profiled radially to match the inlet geometry of the impeller vanes while extending along its central axis towards the pump suction. The auger is preferably radially concentric to the impeller and includes vanes numbered preferably to match the number of vanes on the impeller. The auger is affixed to the impeller, preferably with a lockscrew threaded into a common pump shaft. The radial profile of the auger essentially makes a continuous vane with the impeller, and prevents solids from hanging on the inlet vane tip or center void while providing a smooth flow transition into the impeller.

Abstract: A convertible check valve having a pair of valve body sections, each of which includes a central passageway extending through it is disclosed. Each passageway terminates at an elliptical port. A moveable flapper is located within the check valve between the valve body sections and is movable between a between a closed state and an opened state, and vice versa, to effect the selective closing and opening of the ports. The valve body sections are configured to be rotated 180 degrees with respect to each other so that they are in an either an axially aligned state or in an elbow state. The interface between the passageways is formed by two elliptical shaped planar surfaces, each extending at an angle of 45 degrees to the central axis of the associated passageway. The valve also includes a pressure relief assembly.

A cutter mechanism consisting of a stator and rotor set such that they may be installed on the centrifugal pump impeller and casing as original equipment or as a retrofit. A cutter mechanism such that when installed in a centrifugal pump they prevent stringy materials, garbage and other agglomerated soft wastewater solids from partially restricting or totally blocking the inlet to the pump impeller. A cutter mechanism such that when it prevents solids from restricting or blocking the impeller inlet, it does so without significant decrease of flow throughput or significant increase in absorbed hydraulic horsepower.

Abstract: A labyrinth seal for sealing an impeller shaft within a pump housing. The seal includes inner and outer coaxial, relatively rotatable members secured to the shaft and the housing, respectively. Defined between the two members is a succession of axially extending sleeve-shaped passages of decreasing diameters progressing toward the pump interior, these passages being connected by radially extending disc-shaped passages. Fluid moving through the sleeve-shaped and disc-shaped passages flows into annular grooves formed at the ends of these passages, setting up currents which resist fluid flow through the seal.
