A practical pump will never be able to convert all of its kinetic energy into pressure energy. Parts of energy will always be lost internally or externally. Internal Losses loss [...]
Critical systems should always be equipped with more than one pump. The choice between installing one or more backup pumps depends on installation costs and how critical [...]
In addition to being highly versatile and complete, pneumatic diaphragm pumps are very simple, from installation to day-to-day use. They are powerful equipment that deliver a [...]
Pressure in a fluid is defined as: “the normal force per unit area exerted on an imaginary or real plane surface in a fluid or gas” The pressure equation can be [...]
Solubility is the ability of a solute to dissolve in a solvent. The solubility of one substance in another is not unlimited, and the amount of solute you can resolve in one [...]
Viscosity is the resistance to shear or flow in a fluid – and a measure of the adhesive/cohesive or frictional property. The viscosity that arises due to internal molecular friction [...]
Absolute or dynamic viscosities for some common liquids at a temperature of 300 K are given below: Fluid Absolute Viscosity (N s/m 2 , Pa s) (centipoise, cP) (10 -4 lb/s [...]
When it comes to chemical transfer, safety is essential, both to protect the physical integrity of workers and to prevent accidents. As there are numerous [...]
Minor loss coefficients (pressure or pressure drop) for air duct components. Minor or dynamic losses in pipeline systems are pressure losses caused by a change in the direction [...]
Cavitation occurs in fluid flow systems where the local static pressures are below the vapor pressure of the fluids. Cavitation is a common problem in pumps and valves [...]
Rapidly closing or opening valves – or initiating pump shutdowns – can cause pressure transients in pipelines known as surges or water hammers. A “Coup of [...]
We already know that pneumatic diaphragm pumps are excellent value for money for companies, but what is their cost over their entire period of use? These devices are [...]
