Abstract: One or more systems are disclosed for leak detection for a pump that include a reservoir having a chamber with an inlet and an outlet. The inlet is configured to couple to an exhaust of a pump and the reservoir is configured to create a vortex flow therein. An optical sensor is positioned at a bottom of the reservoir with a detecting portion of the optical sensor extending into the chamber. The vortex flow causes one or more liquids to settle at the bottom of the reservoir on the optical sensor. The one or more liquids are indicative of a leak and the optical sensor is configured to detect the one or more liquids.

Abstract: Technologies are generally described for pump devices that include an adaptive cutwater and impeller arrangement. The power end of the pump device can be coupled to a motor to drive an impeller. The primer plate and impeller of the pump device are removable from the pump casing such that the primer plate and impeller can be replaced or modified as desired for different applications. In some examples, the pump casing includes a primer plate that is removable from the pump casing, where the primer plate includes a discharge cutwater tongue that is specifically spaced and sized to service an impeller of a desired design. The discharge cutwater tongue and impellers in the pump device may thus be serviced for replacement parts, as well as to modify the pump device for different fluids of different fluids properties or hydraulic requirements as may be needed in different applications.
