LIQUID PUMPING UNITS, AND RELATED SYSTEMS AND METHODS

A pump tray has a liquid pump with an inlet and outlet. A blindly matable liquid coupler fluidicly couples with the pump inlet and a blindly matable liquid coupler fluidicly couples with the pump outlet. A chassis of the pump tray has an alignment member configured to removably engage with another device and to restrict, to a limited number of degrees-of-freedom, movement of the chassis relative to the other device (e.g., a liquid pumping unit). The blindly matable liquid couplers are so physically coupled with the chassis as to inhibit movement of them relative to the chassis. A liquid pumping unit also has a chassis defining a bay configured to receive a pump tray, a liquid inlet coupler and a liquid outlet coupler, and a reservoir fluidicly coupled with the liquid inlet coupler. A blindly-matable liquid coupler fluidicly couples with the reservoir outlet and a blindly-matable liquid coupler fluidicly couples with the liquid outlet coupler. An alignment member is configured to removably engage with the pump tray and to restrict, to a limited number of degrees-of-freedom, movement of the pump tray relative to the chassis of the liquid pumping unit.
