The Sprengel pump is a vacuum pump invented by Hanover-born chemist Hermann Sprengel in 1865 while he was working in London. The pump could be run continuously and without any supervision to achieve the lowest vacuum achievable at that time.

"Steam pumps are force pumps operated by steam acting on the piston of a steam engine directly connected to the pump, and in many cases cast with the pump. A section of a double-acting steam pump, showing the steam and water cylinders, with other details, is illustrated [here]." —Hallock 1905

An illustration showing the application of a jet condenser to pump a well. The steam enters the engine and leaves as exhaust. The exhaust steam is cooled by the well water in the jet condenser, then gets pumped into a separator. One stream exits into the sewer, and the remainder is pumped to the boiler as liquid and recycled into the condenser as steam.

"The design is to produce a continued stream, by simply turning it into a crank, thus converting the piston into cog-wheels and the vertical motion into a rotary one." -Comstock 1850

An illustration of the water entering and exiting the condenser through pump. The cooling water enters the circulating pump R, exiting at pipe M. The steam enters at pipe S, and is cooled, or condensed. The condensed steam enters pump B, removing the air in the system.

"It consists of a common metallic syringe, A, screwed to a cylindrical valve box, B, which contains two ovoid cavities, in each of which there is a loose, spherical metallic valve. The ends of the cavities are peirced, and the valves fit exactly, either of the orifices. Thus it makes no difference which end of the valve-box is upturned, the valve falling down and closing the orifices in either direction. The flexible india rubber tubes, C D, are attached to the opposite ends of the cavities." —Comstock, 1850

A syringe is a simple piston pump consisting of a plunger that fits tightly in a tube. The plunger can be pulled and pushed along inside a cylindrical tube (the barrel), allowing the syringe to take in and expel a liquid or gas through an orifice at the open end of the tube.

A pump is a device used to move fluids, such as liquids or slurries, or gases. A pump displaces a volume by physical or mechanical action. One common misconception about pumps is the thought that they create pressure. Pumps alone do not create pressure; they only displace fluid, causing a flow.
