2. Rutherford (rocket engine) - Wikipedia

   en.wikipedia.org/wiki/Rutherford_(rocket_engine)

   It uses LOX (liquid oxygen) and RP-1 (refined kerosene) as its propellants and is the first flight-ready engine to use the electric-pump-fed cycle. The rocket uses a similar engine arrangement to the Falcon 9 ; a two-stage rocket using a cluster of nine identical engines on the first stage, and one vacuum-optimized version with a longer nozzle ...

3. Flow battery - Wikipedia

   en.wikipedia.org/wiki/Flow_battery

   A typical flow battery consists of two tanks of liquids which are pumped past a membrane held between two electrodes. [1]A flow battery, or redox flow battery (after reduction–oxidation), is a type of electrochemical cell where chemical energy is provided by two chemical components dissolved in liquids that are pumped through the system on separate sides of a membrane.

4. Liquid-propellant rocket - Wikipedia

   en.wikipedia.org/wiki/Liquid-propellant_rocket

   An electric motor, generally a brushless DC electric motor, drives the pumps. The electric motor is powered by a battery pack. It is relatively simple to implement and reduces the complexity of the turbomachinery design, but at the expense of the extra dry mass of the battery pack. Example engine is the Rutherford designed and used by Rocket Lab.

5. Hibar Systems - Wikipedia

   en.wikipedia.org/wiki/Hibar_Systems

   Hibar Systems Ltd was a Canadian manufacturer of automated, precision liquid dispensing and filling systems. Hibar was started in 1974 when German-born Canadian engineer Heinz Barall developed a prototype of a precision metering pump that would dispense a small, precise amount (two microlitres) of electrolytes into button cell batteries. Barall ...

6. Electric-pump-fed engine - Wikipedia

   en.wikipedia.org/wiki/Electric-pump-fed_engine

   An electric cycle engine uses electric pumps to pressurize the propellants from a low-pressure fuel tank to high-pressure combustion chamber levels, generally from 0.2 to 0.3 MPa (29 to 44 psi) to 10 to 20 MPa (1,500 to 2,900 psi). The pumps are powered by an electric motor, with electricity from a battery bank.

7. Drum pump - Wikipedia

   en.wikipedia.org/wiki/Drum_pump

   Drum pumps on barrels. Drum pump, barrel pump, and transfer pump refer to pumps that are used to empty barrels, tanks, IBCs and drums. [1] Many liquids used on manufacturing and processing plants are delivered in 100 or 200 litre barrels and are too heavy to tip to empty the liquids inside.
