Water treatment – Aqueous VCI solutions have been used to flush/rinse pipelines, pumps, manifolds, enclosed pits, heat exchangers, etc. as preparation for mothballing/storage. Specialty covers – VCI film covers have been used to protect flanges , valves , etc. in harsh environments such as chemical processing plants, offshore platforms, etc ...
The term "metering pump" is based on the application or use rather than the exact kind of pump used, although a couple types of pumps are far more suitable than most other types of pumps. [2] Although metering pumps can pump water, they are often used to pump chemicals, solutions, or other liquids.
The water industry commonly uses a blended-phosphates formulation to deal with both issues. [7] Phosphates convert any leached ions into a layer of scale that acts to separate the metal piping from the water. [8] Phosphate-type inhibitors may cause eutrophication issues downstream or directly encourage algal growth in uncovered, treated water ...
Since valves are used in this two-cylinder pump. it is limited to grain sizes of 8 mm at most. Which type of valve is selected will depend on the high-density solids to be conveyed. For materials containing grains with a solids content up to 50% a sharp-edged metal valve seat is required.
A concrete pump is a machine used for transferring liquid concrete by pumping. There are different types of concrete pumps. A common type of concrete pump for large scale construction projects is known as a boom concrete pump, because it uses a remote-controlled articulating robotic arm (called a boom) to place concrete accurately. It is ...
A progressing cavity pump is a type of positive displacement pump and is also known as a progressive cavity pump, progg cavity pump, eccentric screw pump or cavity pump.It transfers fluid by means of the progress, through the pump, of a sequence of small, fixed shape, discrete cavities, as its rotor is turned.
Inductive pumps have been used in many different applications such as the following: Industrial chemical feed systems; Water Treatment chemical injection process; Oil bearing lubrication of industrial pump and motor bearings (Block and Budris, 2004) Automotive pumping systems i.e. fuel pumps, vacuum pumps, exhaust treatment pumps etc.
Concrete sealers are applied to concrete to protect it from surface damage, corrosion, and staining. They either block the pores in the concrete to reduce absorption of water and salts or form an impermeable layer which prevents such materials from passing.
