From Semler Industries, Inc.'s website:
Since its inception in 1905, Semler Industries Inc. has become a recognized leader in the liquid handling field. Initially a distributor and fabricator, Semler has also evolved into a designer and manufacturer of proprietary systems for liquid handling applications. Worldwide, Semler Industries has become the pipeline that delivers selected product and custom assembly skills to specialized liquid handling problems. Located just south of Chicago's O'Hare airport, we are able to quickly supply materials to all parts of the world.

|
Centrifugal pumps consist of a set of rotating vanes, enclosed within a housing or casing, that are used to impart energy to a fluid through centrifugal force.
|
|
Check valves are self-activating safety valves that permit gases and liquids to flow in only one direction, preventing process flow from reversing. They are classified as one-way directional valves.
|
|
Diaphragm pumps use a diaphragm that moves back and forth to transport liquids from one place to another.
|
|
Drum pumps are used to transfer materials from a container into a process or other container. They may be electrically, hydraulically, or pneumatically powered depending on the working environment or application.
|
|
Filtration media and elements are designed to remove suspended particles from a process stream. This product area includes bulk filter media, cartridges, housing-only products, and housing and filter assemblies.
|
|
Gas distribution systems consist of vaporizers, gas cabinets, gas manifolds, mass flow controllers, valves, pressure sensors and associated interconnect tubing configured to deliver bulk and specialty gases to process equipment.
|
|
Gear pumps use intermeshing gears to pump various types of liquids. Typically, one gear is the driver and the other is free wheeling. The gears have very tight tolerances so that the fluid being pumped cannot pass through them. Common uses for gear pumps include high pressure, metering, and flow control applications.

|
Hand pumps and foot pumps are manually operated pumps that can driven by hand or foot via a handle or lever.
|
|
Hose reels are used to wind, unwind, and store lengths of hose that are designed to transport gases and liquids for industrial applications.
|
|
Industrial hose covers the broad spectrum of fluid transfer lines. Hose is usually flexible, often reinforced, and available in a wide range of material compositions to cover various hydraulic and pneumatic industrial applications.
|
|
Industrial liquid handling pumps are classified in many different ways, and are distinguished by the media pumped and the fluid motive mechanism (dynamic or displacement).
|
|
Industrial valves are classified in many different ways. They can be distinguished by material of construction, media handled, and/or application.
|
|
Liquid filtration elements are used to remove impurities from liquids. They are used in water treatment systems and fluid processing applications.
|
|
Loading arms are used to load liquids into tanks, trucks, railcars, and other vehicles. They are commonly used in fueling and fluid transfer applications.
|
|
Piston pumps and plunger pumps are reciprocating pumps that use a plunger or piston to move media through a cylindrical chamber. The plunger or piston is actuated by a steam powered, pneumatic, hydraulic, or electric drive. Piston pumps and plunger pumps are also called well service pumps, high pressure pumps, or high viscosity pumps.
|
|
Progressing cavity pumps are a type of rotary positive displacement pump designed to transfer fluid or media with suspended solids or slurries from the suction side of the pump to the discharge side of the pump, from storage tanks or through pipelines.
|
|
Reels are devices around which lengthy, continuous items such as cable, wires, paper, etc. are wrapped for transportation or storage.
|
|
Rotary vane vacuum pumps and systems move media through the pump using a rotating assembly in the pumping chamber. Typically, there are two or more rotating vanes that move the media from inlet to outlet. Rotary vane vacuum pumps are positive displacement pumps.
|
|
Sample dryers are used to remove liquids from a sample through techniques such as freeze drying, spray drying, and evaporation.
|
|
Sanitary pumps are used to transport and meter solutions, slurries, and colloids of food and agricultural materials in operations such as food processing that require cleanliness. There are four basic types of sanitary pumps: centrifugal, positive displacement, jet, and airlift.
|
|
Strainers are placed in-line with process piping to remove large solid contaminants from the flow. Strainers can be cleaned and reused.
|
|
Sump pumps are used in applications where excess water must be pumped away from a particular area. Sump pumps generally sit in a basin or sump that collects this excess water.
|
|
Tube fittings connect runs of tubing for in-line, offset, multi-port, and mounting configurations to other tubing sections, pipe, hose, and other fluid transfer components.
|
|
Tubing is used to transport fluid and gas in pneumatic, hydraulic, or process applications. Tubing differs from pipe in that tubing's outside diameter or size is controlled and used for product designation.
|
|
Vacuum pumps and vacuum generators provide sub-atmospheric pressure for a variety of industrial and scientific applications where a vacuum is required.
