=Introduction=
Moving large volumes of liquid is tedious by bucket or barrel.  Pump and hose require less effort and are more convenient.

=Challenges=

=Approaches=
Replimat uses self-priming, particulate tolerant, membrane pumps manufactured with pressure switches and for a variety of DC voltages, for RVs.  This style of pump is relatively inexpensive and widely available.

======Rationale======
Membrane pumps can be motor or solenoid driven, are tolerant of particulates and debris, lend themselves to being printed, and are widely used for a variety of demanding applications.
