Pump dispenser nd 10 diaphragm device. Types and characteristics of metering pumps. Advantages and disadvantages of diaphragm ID

For a layman in pump technology, choosing the most suitable pump technology for a particular application or process system can be challenging because many of today's pumps are so versatile that they are suitable for a wide range of applications. peristaltic pumps and piston pumps with forced displacement all the transverse boundaries of the application, where you want to enter a specific volume of fluid into the process system.

Choosing which one is the best option requires careful consideration and should always include the experience of the pump manufacturer. In cases where the application has a requirement for in-line dispensing and dispensing of liquids, a forced-displacement reciprocating pump has historically dominated the market and continues to do so. The problems associated with the choice of a metering or metering pump, unlike other types of pumps, are usually related to the accuracy of the flow range and the fact that the pressure fluctuations within the process do not affect the power, which is the case with rotating pumps.

The wide range of applications for these pumps is significant: with market sectors ranging from toiletries and detergents to pharmaceuticals, water and waste, food and beverage processing, power generation, chemical processing, petrochemicals and oil and gas.

Membrane or diaphragm

The metering pump is equally unpretentious with the addition of aromas and colors to the toiletries, as it pumps hydrocarbon condensate on the shelf and liquid carbon dioxide in cryogenic loads. The most common problems facing users are improving security, increasing efficiency, and lowering operating costs. The first two issues were resolved by designing diaphragm pump heads that prevent product leakage and contribute to increased safety and more economical use of ingredients.

Users are also aware of the total life-cycle costs that take into account known factors, such as initial investment and subsequent spare parts, maintenance, downtime, energy consumption and efficient use of the processed product.

The application usually defines the pump used, therefore it is important to clearly understand the characteristics of the fluid, such as viscosity, solids content, abrasiveness, corrosivity, toxicity and hygiene. Other parameters must also be considered, including volume and supply pressure, temperature, flow characteristics and vapor pressure.

The correct material for the pump head must be selected according to the characteristics of the fluid. For toxic materials or demanding applications where safety and security are a priority, the diaphragm head is usually the first choice. For less demanding applications, a plunger pump head will usually suffice.

Since metering pumps are commonly used as part of an integrated treatment system, several factors influence which type is appropriate. These may include net positive calculations of the suction head, an overview of the diameters and lengths of the inlet and outlet pipes, as well as any limitations in the system. The environment also plays a role in the selection of pump materials. Metering pumps are used in the most difficult conditions and conditions, ranging from offshore oil and gas platforms, where frequent temperatures are other than zero, in remote deserts, where the temperature is high, and sand output is a great opportunity or in tropical areas where moisture needs to be removed.

Each type of fluid will affect the material used for the pump components. Only when the full profile of the pumped medium and the processes are fully documented can you indicate the type and design of the metering pump. When compiling this profile, it is always wise to review any previous pumping-liquid experiments.

The dosing pump is highly versatile and ideal for continuous, in-phase measurement of single or multiple liquid systems at different speeds. It is noteworthy that this is the only pump with two flow control methods - speed and stroke length, which can be used independently or simultaneously to ensure optimal performance.

For example, in a process where an ingredient must be carefully added to a variable main stream, the proportion can be maintained by adjusting the speed, while any adjustments necessary to maintain the quality of the product can be made by adjusting the stroke length. The metering pump can be precisely tuned to the requirements of the process system. Manual, pneumatic or electrical control options are available, such as explosion-proof designs for pumps used in hazardous areas.

Basic technology has proven itself, and ongoing development through the introduction of new manufacturing processes and materials means that these pumps keep pace with the growing and diverse demands of all industries. Simple design and few components provide low noise and high volumetric efficiency.

Mechanical and hydraulically controlled diaphragm pump heads were the focus of new developments in metering pump technology. These pump heads are usually indicated when toxic materials are being processed and leakproof characteristics are required. Thanks to the wider variety of materials that can be used for diaphragms, diaphragm pump heads are now able to withstand hazardous, toxic and hazardous fluids at varying flow rates and pressures. With more emphasis on safety and the environment, as well as the enactment of new legislation, users are increasingly turning to diaphragm pumps and traditional plunger designs.

Users are advised to look for pump head designs with a diaphragm failure indicator, as this design without a pump head will continue to provide continuous service even in the event of a single diaphragm failure. The high pressure transmission options for hazardous liquids have traditionally been limited to piston centrifugal pumps with fixed-stroke piston pistons, high-speed or multi-stage centrifugal pumps. All of them have their limitations associated with sealing, wear and subsequent leakage potential.

Process diaphragm pumps can provide a smooth product flow over a wide operating range, including low speeds, and will cover the widest possible range of duties for all critical pressure processes. Thanks to the use of low maintenance gears, energy consumption is reduced to an absolute minimum and almost silent operation is ensured.

Metering pumps are used for single point or multicomponent dosing in all areas of industry. Single point dosing usually involves the addition of a specific fluid accurately and proportionally on an ongoing basis. Several fluid applications can be processed on a multi-headed pump unit driven by a single engine, while individual liquids are dispensed independently from each other at specified points in the process or collected together to create a mixture.

This application may contain various liquids in any range of flows and proportions. Each of the components of the liquid is mixed in the correct proportions in accordance with the recipe to obtain the desired mixture. Changing requirements in the technological process prompt pump manufacturers to study modern technologies with the aim of developing new technologies and materials. At the same time, there is a desire for more economical and effective dosing and dosing systems.

The dosing and dosing market is very diverse, and the requirements of each industry are different. However, relying on the experience gained in one industry and applying it to another, it turned out to be very effective in the process of system design. Although the basic concept of a dosing and dosing system is standard, the pump manufacturer knows how and where its components are configured for each application. Thus, the burden of responsibility is that all available data can be taken into account to facilitate the development and selection of solutions.
