Document Type and Number:
WIPO Patent Application WO/2024/081870
Kind Code:
A3
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.
