Liquid Handling Pumps

(2,421 companies)
The image below shows a simplified centrifugal pump layout: Image Credit: Engineers Edge. Centrifugal pumps can be further differentiated based on how they direct flow. Axial flow pumps lift liquid in a direction parallel to the pump shaft...

...degradation due to moisture, salt spray, oxidation or exposure to environmental or industrial chemicals. Non-destructive evaluation (NDE) test and inspections evaluate the properties of a material without causing damage. Common NDE methods include...

Fume Hoods

...and closed to maximize access and minimize airflow. Fume Hood Efficiency. The efficiency of a fume hood is measured by its hood face velocity and required air flow. Hood face velocity is a measurement of air flow speed across the imaginary plane...

Air Pressure Regulators

(427 companies)
...elements comprise: a pressure regulator. A pressure reducing element, a sensing element, and a reference force element. When operating, the force element produces a force that opens the reducing element. Pressure introduced into the inlet port then flows...

Blowout Preventers

(37 companies)
Blowout preventers (BOPs) are specialized valve assemblies that prevent uncontrolled flow of formation fluid during well drilling operations. Several assemblies are typically stacked to create a fail-safe mechanism.

Tube Fittings

...solvents. Hydraulic fittings must have seals which prevent the leakage of liquid and often be resistant to rust or other possible chemical corrosion. Pneumatic applications involve the transfer of gases. Pneumatic fittings must have very tight seals...

Flow Meters

(1,665 companies)
Flow meters (flowmeters) and flow sensors are devices used for measuring the flow rate or quantity of a moving fluid or gas.

Back-up Rings

(122 companies)
Back-up rings or anti-extrusion rings are washer-like devices used to prevent seals from extruding through gaps while under pressure. Seals are installed in the downstream side of the gland.

X-ray Sources

(59 companies)
X-ray sources are lamps that generate or produce X-rays, a form of electromagnetic radiation, for non-destructive testing (NDT) or inspection.
...the gauge will be used. Bottom -- This is sometimes called a stem mount, and the mount connection is on the bottom of the gauge. Back -- Back mounting can be found in the center or lower back of the gauge. The mount connection will protrude from...
Flow and pressure (fluid dynamics) testing services evaluate the flow, pressure and fluid dynamics of components and products such as radiators, heater cores, lines and bottles.

Pressure Gauges

...through the high port and the lower through the low port. It is commonly measured in units of pounds per square inch. An example of a differential pressure sensor is a filter monitor; when the filter starts to clog the flow resistance and therefore...

Pressure Sensors

(1,096 companies) capacitance that is detected by a bridge circuit. Design Tip: The electronics for signal conditioning should be located close to the sensing element to prevent errors due to stray capacitance. The capacitance of two parallel plates is given...

Turbidity Instruments

...flowing at between 0.1 and 1 liters per minute. Because on-line devices are subject to continuous flow and sampling, their detectors must be cleaned frequently to prevent fouling and eventual failure. Three designs: benchtop, portable, and on-line...
...high currents while limiting over-voltage. GDTs with very low capacitance and very high insulation resistance have little, if any, flow effects on the protected system under normal operating conditions. Voltage and current surges can occur naturally...
