Abstract: A fluid pump module includes a heat dissipation board assembly, a fixing frame body, fluid pumps, a control board and a conveying pipe is provided. The fixing frame body is fixed at one side of the heat dissipation board assembly, so as to form two accommodating spaces between the heat dissipation board assembly and the fixing frame body. Two fluid pumps are respectively disposed in the two accommodating spaces. The control board is disposed at another side of the heat dissipation board assembly. The conveying pipe connects the two fluid pumps in series so as to form a series connection therebetween. The control board controls operations of the fluid pumps, and the heat dissipation board assembly dissipates heats produced by a module formed by the two fluid pumps.

Abstract: A pump cartridge for mounting on a drive rotor includes a roller assembly having first and second hubs maintained in a spaced apart relationship and defining an axis, and a plurality of planetary rollers arranged in a circumferentially spaced orientation about the axis, the rollers mounted to the hubs displacement radially outward. One or more compressible tubing lines are interposed between the rollers and an interior wall of the pump cartridge housing. The housing and the first and second hubs collectively define a passageway through which a spreader on the drive rotor extends and may be rotated relative to the roller assembly to displace the rollers radially outward to thereby compress the tubing lines against the interior wall. A coupling feature on the first hub engages a roller driving feature of the rotor, so that rotation of the rotor causes rotation of the roller assembly about the axis.

Abstract: A pipeline for conveying concrete determines a pressure in and/or a wall thickness of the pipeline, wherein a first length portion of the pipeline has a first wall thickness and a second length portion of the pipeline has a second wall thickness greater than the first wall thickness. The determination is made using a first strain gauge on an outer side of the first length portion and a second strain gauge on an outer side of the second length portion, wherein the strain gauges are each fixedly applied to the outer side of the length portions. A strain gauge and/or the second longitudinal section of the pipeline are/is at a spacing from at least one end of the pipeline, which spacing corresponds to at least an internal diameter of the pipeline. By comparing strain gauge measurements, the wall thickness is determinable.

Abstract: This disclosure includes plunger pumps having leak detection systems. Some pumps include a housing having a bore, an inlet, and an outlet, a plunger disposed within the bore and a first seal engaged with the plunger to divide the bore into first and second chambers, the plunger configured to reciprocate within the bore to expel liquid from the first chamber out of the outlet, and a sensor for detecting a presence of liquid in at least a portion of the second chamber. Some pumps have a reservoir for collecting liquid that leaks into the at least a portion of the second chamber, where the sensor is for detecting a liquid level in the reservoir. Some pumps include a second seal engaged with the plunger to divide the second chamber into first and second portions, and the sensor is for detecting a presence of liquid in the second portion.
