A bilge pump system for removing residual fluid from a vessel surface, includes at least one collection unit having a collection base with a collection inlet and a collection outlet, and a pump having a pump inlet flow-connected by at least one tube to the collection outlet. A discharge tube is flow-connected to the pump outlet, wherein the collection inlet comprises at least one opening on a bottom face of the collection base arranged to be on the vessel surface. A sponge is arranged within the opening of the collection base and in liquid communication with the vessel surface. The sponge can be fitted into place by lips or lugs protruding from the collection base.

A frac pump valve seat assembly includes a seat body and a wiper seal. The seat assembly is configured to mitigate the risk of fluid end erosion in the valve seating area by automatically clearing or wiping the mating surface of the fluid end at the time of installation. The wiper seal is located at a lower portion of the seat body and is designed to interface therewith the mating surface of the fluid end. Upon installation, the wiper seal scrapes or cleans the mating surface of propellants, sand, and other contaminants that may remain after initial cleaning. The contact surface of the seat body is optionally further reinforced with material implants with greater hardness than the material of the seat body.

A buoy assembly for use with a pumping system to pump liquid and debris from a flooded shaft or well or any such structure with appreciable depth is provided. The buoy assembly includes a proximal tube that can couple to an end of a hose coupled at an opposite end to the pumping system. A buoy is coupled to the proximal tube that provides the buoy assembly with buoyancy that allows the buoy assembly to float on the liquid in the shaft. The buoy can have one or more aeration ports that can be selectively opened (by removing a plug therefrom) to allow airflow therethrough into the buoy. The buoy assembly also has an adapter socket with feet that define vents therebetween to allow passage of debris via the vents into the buoy. Flow of air into the buoy via the aeration ports facilitates lift of liquid and debris through the conduit during a pumping operation.
