Abstract: A suction diffuser or arrangement is provided featuring a main suction diffuser body and a flow conditioning arrangement. The main suction diffuser body is configured with an inlet to receive an incoming fluid flow, an interior cavity to receive the incoming fluid from the inlet, and an outlet to receive the incoming fluid from the interior cavity and provide an outgoing fluid. The flow conditioning arrangement is configured in relation to the inlet and also comprises a flow conditioning portion having at least one inwardly contoured surface, configured to extend into the interior cavity, diffuse the incoming fluid passing from the inlet into the interior cavity, and provide a flow conditioning that produces a uniform flow of the outgoing fluid by directing the incoming fluid towards the outlet, based at least partly on a contoured design corresponding to the at least one inwardly contoured surface.

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.

Abstract: A discrete valve flow rate converter is provided to obtain a system flow through a valve in a dynamic hydronic pumping system, e.g., based on signaling containing information about the valve's differential pressure and the valve's hydronic characteristics calibration data. The discrete valve flow rate converter resolves the valve system flow rate directly and accurately with the valve's open position and the corresponding valve differential pressure signals associated therewith. The discrete valve flow rate converter may be applied to all kinds of valves as long as their open position and differential pressure associated with is available, e.g., including implementations for control valve applications, e.g., where the valve open position is controlled automatically and accurately, as well as implementations either for pumping system pressure controls with the flow rate known, such as adaptive hydronic system pressure controls, or as an alternative to sensorless pump monitoring and control.

Abstract: A pump controller has a signal processor that receives signaling about an instant water level AIL of a liquid in a container and generated by a water level transducer during an empty/fill application; and determines corresponding signaling to control a pump during the empty/fill application based upon the signaling received using a liquid level control algorithm that turns ON the pump when the instant water level AIL rises above a maximum empty water level during an empty application, or falls below a maximum fill water level during a fill application; turns OFF the pump when the instant water level AIL falls below a minimum empty water level for the empty application, or rises above a second maximum fill water level during the fill application; controls the pump when the instant water level AIL is in a liquid level region above the minimum empty water level and below a second maximum empty water level for the empty application, or falls below the second maximum fill water level and above a second minimum fill water level during the fill application based upon a respective desired adaptive pressure set point SP* being defined from a respective adaptive liquid level control curve with respect to the instant water level AIL.

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: An adjustable volume sampling system is disclosed for aseptically retrieving a sample volume of a fluid from an origination container. The system includes a sampling container. A cap is removably attached to the sampling container so as to close off the open top. The cap includes two ports. A first tube is attached to one of the ports. An elongated diptube extends through port into the sampling container and an upper end of the diptube is located inside a portion of the first tube. The diptube can be raised and lowered relative to the sampling container by pinching an stretching the first tube. Syringes are provided for expelling excess material from the sampling container.

Abstract: A contoured check valve disc features a pivot portion and a check valve portion. The check valve portion is attached to the pivot portion, and has two sides, a first side to respond to the fluid flow in a first direction and move the check valve portion away from a fluid opening to the one or more open positions depending on the fluid flow to allow the fluid to flow through the fluid opening, and a second and opposing side to respond to fluid flow in an opposite direction through the fluid opening and move the check valve portion towards the fluid opening to the closed position to seal the fluid opening and stop fluid flow. The check valve portion a near-sloped portion formed nearest to the pivot portion, having a near-sloped contoured surface curving away from the pivot point to a first point of inflection with a first curvature, and a far-sloped portion formed farthest from the pivot portion, having a far-sloped contoured surface curving away from the point of inflection towards a farthest point away from the pivot portion with a second curvature that is less curved or bent than the first curvature, the near-sloped portion and the far-sloped portion combining to form a combined surface having a contoured pressure/force distribution on the first side to respond to the fluid flow and move the check valve portion away from the fluid opening.
