Abstract: The frame-supported pump is assembled without the use of tools. In place of bolts or threaded connections, an external frame provides the support necessary to resist the internal pressure of the pump. Upper and lower pump housings include grooves that slide into a slotted support or frame—a slip-in mount. In alternative embodiments the grooves are replaced with holes that slide over rods, or other means of external support prevent the pump housings from moving away from each other during pumping. A pin is optionally used to prevent the housings from sliding out of the frame, or friction is sufficient. When the pumps are in service, the internal pressure attempts to push the housings away from each other, but this force is passed to the frame, which responds with a matching force, keeping the housings in place.
