Periodic vacuum-pump cycling lowers container pressure only when needed, preserving produce freshness while cutting energy use and pump wear.

Air-cushion flotation and jet propulsion let a suction head remove residual radioactive sludge without manual tank entry or worker exposure.

Electrical current and ion-selective membranes create osmotic pressure to pump conductive solutions without moving parts, reducing wear and maintenance.

Small gas accumulator tanks use LH2 cooling and vehicle heat to deliver 5-10 bar fuel cell feed without heavy high-pressure storage.

An integrated cap with one-way valves and buoyant closures enables manual or pneumatic oil suction while cutting conduit complexity and air leakage.

A magnetically actuated float valve replaces the control rod to improve landfill well pump reliability in corrosive, debris-laden service.

Variable purge flow restriction keeps purge-port pressure high enough to resist gas backflow during vacuum pump state changes.

Gravity, atmospheric pressure, and compressed air sustain cyclic water flow without pumps, reducing system complexity and energy input.

Overlapping coiled stages and an interstage flow channel raise pressure while keeping fluid converters compact and energy efficient.

Venturi-driven gas ejectors and an argon loop pump molten salt without moving parts, reducing corrosion, wear, and maintenance.

Controlled hydrogen-oxygen detonation creates pressure waves that generate vacuum and pressure in milliseconds with fewer mechanical parts.

Closed-loop gas injection adjusts valve position from sensor feedback to stabilize slurry transfer, cut air use, and reduce pump stalling.
