Systems and methods for connecting and disconnecting pumping equipment

A pumping system for performing a hydraulic fracturing operation, comprising:

• a first fluid conduit having a central axis and in fluid communication with a subterranean borehole;
• a fluid surface pump including a pump body and a pump outlet extending from the pump body, wherein the pump outlet comprises a flexible conduit extending from the pump body towards a terminal end of the pump outlet, wherein the terminal end of the pump outlet is configured to discharge a fracturing fluid pressurized by the surface pump through the first fluid conduit, and wherein the surface pump is insertable into the first fluid conduit whereby the surface pump is configured to discharge the fracturing fluid into the subterranean borehole;
• a connector assembly comprising an engagement member having a first position configured to lock the pump outlet within the first fluid conduit and a second position configured to unlock the pump outlet from the first fluid conduit, wherein the pump outlet is prevented from being removed from the first fluid conduit with the engagement member in the first position and the pump outlet is allowed to be removed from the first fluid conduit with the engagement member in the second position, and
• an annular pressure cup coupled to an outer surface of the pump outlet, wherein the pressure cup comprises a radially retracted position whereby an outer surface of the pressure cup is spaced from an inner surface of the first fluid conduit when the pump outlet is inserted into the first fluid conduit, and a radially expanded position radially spaced from radially retracted position whereby the outer surface of the pressure cup sealingly engages the inner surface of the first fluid conduit when the pump outlet is inserted into the first fluid conduit.
