摘要： A pump leakage mitigation device includes one or more clamp arms (120) on an outer surface of a pump (10) that can be driven by a biasing element (110) to seat against a shaft (11) of the pump (10) to seal or reduce fluid flow through a breakdown of the pump (10). The biasing element (110) engages only at threshold temperatures, such as those associated with breakdown orifice failure (12) when additional sealing may be necessary. Clamp arms (120) of any number and shape can be used to achieve the desired seal and based on the pump geometry. A sealant surface (125) and/or keeping mechanism are useable with the leakage mitigation device to enhance fluid flow blockage throughout a pump failure transient scenario. Pump leakage mitigation devices are installed on an outside of a variety of different pump types and can thus be installed, actuated, manipulated, disengaged, and/or removed without having to destroy or disassemble the pump (10).
