APPLICATION OF PUMPS

Application of Pumps – Depending on the specific task, the pumping equipment of various types and operational principles may be applied to the same area. Here we’ll discuss the return of pump groups associated with their purpose.

Metering pump

Metering Pump equipment is supposed to dose planned quantities of fluid. Positive displacement pumps are ideal for this purpose: piston, membrane etc., allowing for metering the planned transfer medium and stopping fluid flow. These pumps may be given different systems or have some design particularities to perform such. Piston pumps may be equipped with many operating cavities that are actuated by the single drive and have offset operative cycles relative to every alternative. Some models are also equipped with a mechanism for adjusting the hole operating volume to supply a lot of accurate dosing. For control and dosing, the pumps of this type are equipped with stepper motors or alternative control devices. Therefore the operational device would execute the planned movements. Particularities of the enforced form of the pump are also considered for dosing functions. For example, membrane pumps are used once metered fluid is poisonous, with chemicals aggressive or explosive. For more information, visit Dosing Pumps.

Slurry pumps

Slurry pump equipment is intended to withdraw fluids with a high content of solids of various sizes. It may be bottom sediment from multiple reservoirs, tanks and foundation pits, river sand and slurries. Slurry pumps may be of normal submerged or semi-submerged construction. Centrifugal pumps are sometimes enforced for these functions. Meantime further requirements are applied for them: resistance to abrasive wear and skill to transfer a medium with a high content of solids. These options are provided by using wear-resistant materials and selecting the best relation between blade rotation speed and size. If rotation speed lowers, abrasive wear of its elements will increase, and size will increase accordingly.

Booster pumps

Has to design an air pump (oil-vapour, steam-jet, mechanical etc.). A booster pump is a component of pump units intended for pressure increasing or providing an extra vacuum in the system. It’s used in the installation systems for the increase of heads. A booster pump may be put in before the main operational pump to produce the operation of the latter in mode while not cavitation or to produce intake of fluids from small vessels.

Mud pumps

Mud Pumps are a single-purpose type of pumping equipment enforced in drilling equipment and should provide mud fluid circulation in drilled wells. Axial, plunger and piston sorts pumps are used. Construction of such a pump may be of rotodynamic or positive displacement type. Such severe operation conditions are the reason for many necessities for mud pumps. They need to give a constant and uniform feed of mud fluid to prevent the unwanted influence of pulsations. Meanwhile, they must be powerful enough to circulate fluid and resist abrasive wear by leaked fluid. It may give a chance to repair and replace broken components quickly.

Deep-well pumps

Deep Well pump equipment is primarily of semi-submerged design; once below the level of pumped fluid, there’s only an operational device – the blade. These pumps have a long cylindrical body that simplifies installation into a working position. Deep suitable pumps can high head, enough not just for fluid lifting but for its feeding trough pipeline addition; the name implies, the deep-well pump is applied for liquid lifting out of assorted wells and pits. They will be used for water systems from flowing beds and pumping water out of flooded basements and trenches. Submerged pumps may also be used in mining, chemical, construction and alternative industries.

Foam pumps

Foam pump equipment is intended for transferring emulsions and pulps with varied coefficients of phases. A vertical foam pump is constructed in one device with an engine, dedicated reservoir, and pump. Identifying a feature of foam pumps is a conical reservoir with tangential emulsion intake. The rotating blade creates a vortex cavity of the transferred medium during this intake, separating the gas half. The liquid half falls onto the operating edge and is discharged from the nozzle.

The main feature of this type of pump prescribes its area of application. Foam pumps are used in any facility, wherever necessary, to transfer varied sorts of emulsions. Such pumps are used in waste treatment facilities, wherever it’s essential to remove the floating layers in floatation facilities, enrichment plants, and oil-producing and oil-refining facilities. Foam pumps also are used for construction since they can pump construction mixes.

Fire pumps

A fire pump is a console pump that is outfitted for firefighting functions. Since the pump doesn’t have the self-priming ability, it may be connected to the air pump for priming if water is drawn from the water body. If firefighting fluid is removed from the tank on top of the level of the suction nozzle, then priming isn’t necessary. The fireplace pump may also have a pressure gauge and system for a dynamic head amendment to prevent damage to the pump or firefighting hose in case the latter is quenched or clogged. If foam mixture is employed for firefighting, then fireplace pumps are equipped with foam mixers for forming, wherever pumped water is mixed according to predetermined proportion with a foam-producing agent delivered from a separate vessel.
