Liquid ring vacuum pumps are designed to be rugged and simple to operate. These pumps are available in single & two stage models, and many different materials construction such as cast iron, steel, aluminum, bronze, and stainless steel. It comprises of one rotating part, and a multi-bladed impeller keyed to the pump shaft. The impeller is mounted eccentrically in a round pump housing. As the impeller rotates, centrifugal force throws the seal liquid against the outside wall forming a liquid ring.

Liquid sampler is used to collect samples of domestic wastewater in various stages of treatment automatically. It has an outer cylindrical liquid that is used for collecting container provided with a longitudinal opening or slot in the wall. It consists of inner tubular member mounted for rotation in the outer container, which is provided with a substantial spiral slot or opening in the wall. The inner member rotates the longitudinal slot and the spiral slot provides a moving aperture for the collection of liquid samples at varying depths.

Liquid sensing cable detects leaks of petroleum based liquids along the full length of the cable, and water at the end of the water sensing wires. The water sensing wires may be separated from the cable and can be field tailored to any desired level or location for more efficient monitoring around tanks, piping, pumps, dispensers, or other critical leak detection areas. It can detect many liquids include water, gasoline, diesel, waste oil, and petroleum products.

Liquid slugging is an effect of pouring a liquid into the cylinders of an operating automobile engine. It is a condition, which occurs when liquid is allowed to enter one or more cylinders. Because liquid is practically non-compressible, the compressor seals may be compromised when the pistons attempt to compress the liquid. Liquid slugging can lead to permanent valve damage and reduced compressor efficiency. The units start out requiring that its filters be replaced.

Liquid springs compress a pressurized liquid. The liquid springs consist essentially of a stout cylinder, stressed to withstand very high pressures, enclosing a piston and road assembly adequately sealed at the road end by high -pressure seals. A single liquid spring can provide as much springiness as 30 coil springs of the same length and diameter or a single large spring many times larger.
