For various industries, the production process relies on the precise and correct dosage of chemicals. A product might undergo a radical transformation or become inherently dangerous with just a small adjustment to a single chemical. Dosing chemicals accurately on such a large scale is beyond the capabilities of humans. Consequently, a chemical dosing pump is essential.
A chemical dosing pump is specifically engineered to consistently and precisely inject a predetermined amount of chemical substances into a gas, steam, or water flow. Choosing the best chemical dosing pump can be difficult due to the variety of options available.
Here’s how to choose a chemical dosing pump
If you want your chemical dosing pump to work as efficiently as possible while keeping your system secure and experiencing as little downtime as possible, choose it carefully. When selecting a chemical dosing pump, it is important to keep in mind the following details:
Identifying your needs
You should know exactly what you’ll use the dosage pump for before buying it. For efficient dispersion, you should know the medications or chemicals you will be utilizing, the amount of substance provided, and the required pressure. Using this information, you can select a chemical dosing pump that meets your needs regarding accurate supply ability and capacity.
Materials for construction
Numerous materials help in the production of a chemical dosing pump. Use heavy-duty pumps constructed of materials that can withstand the test of time if your pumps are intended to handle extremely corrosive chemicals in their daily operations.
Fluid temperature
Dosing pumps, such as diaphragm-type pulse injections or peristaltic pumps, should only be chosen after knowing the dose and temperature requirements of the fluid. Due to the high volume and frequency of fluid pumping, this insignificant detail could become a major issue if appropriate components aren’t utilized.
Knowing the pressure
The dosing pump’s inlet and outlet are affected by more than just temperature. Accurate measurement of the pressure level is necessary to select the appropriate equipment. So, the foundation of liquid dosing is selecting pumps capable of handling the required pressure range.
Technical features
When selecting a chemical dosing pump, consider the necessary technical features. Reliability, precision in supply quantity adjustment, working pressure, durability, supply flow rate, and power are all aspects of a pump that must be considered. Make sure the chemical dosing pump you choose can handle the conditions by selecting qualities that are important to you.
Should a leak occur?
Leaks, especially in industrial equipment like big dosing pump settings, are common over time. A common reason for this is using a dosing pipe unsuitable for the fluid or the fluid’s corrosive characteristics.
More recent dosing pump versions automatically notify the operator when a leak is detected, including leak protection options. Such alert and control mechanisms are typically absent in earlier versions or in cases where the quality of the metering pumps purchased is compromised. Equipment that stays too hot until the leak is found might render the system inoperable. This leads to additional production downtime costs.
Some metering pumps allow you to control the flow rate remotely. This can prevent the introduction of large amounts of unnecessary chemicals into the treated fluid. Other pumps have alarms built into the diaphragm head or are signal-controlled.
Pumping fluid types
Thinking about the fluids you’ll pump is an important factor in preventing corrosion, wear, and tear. If you need to pump a slurry, a thick mixture of solids and liquids, you should get pumps with specialized injectors, diaphragms, and other parts.
Viscosity does matter
A fluid’s viscosity indicates its resistance to warping at a specific rate. When a fluid is very thick and sludgy, with the possibility of semi-solids or solids, it is said to have high viscosity. For distilleries and water treatment plants, this is of paramount importance. This is because it has a profound impact on the final product.
A powerful dosing pump with long-lasting components is essential for any business that deals with thick or muddy water or fluids.
Working conditions
Think about the things to which they could be exposed while working. Because of this, there are feed pumps that can endure the most extreme conditions. These pumps have characteristics such as stroke brackets and chemically resistant housing and are completely enclosed and encapsulated.
Calculate costs
Before you buy a chemical dosing pump:
- Figure out how much money you have to spend.
- Think about how much you’ll spend on the pump in the long run, especially on future part replacements, maintenance, and running costs.
- Consider the total costs during the usage time, not just the initial fee.
Look at user opinions and reviews
You should read user reviews and ratings of the chemical dosing pump you’re considering before buying it. This will give you a general idea of how well and reliable the product is. Feel free to ask previous users for their thoughts and experiences.
What runs the chemical dosing pump
Whether or not your chemical dosing pump is powered by the same source as your plant or factory is the most basic, yet often disregarded, consideration when selecting the appropriate pumps. The reason is that certain locations do not use any electricity at all, instead relying solely on standard thermal energy, solar power, or natural gas. Ideally, your plant would include connections for every possible power source. However, in practice, it is more common to need to verify that the pump is compatible with the specific power source you intend to use.
Common applications for a chemical dosing pump
There are a variety of industrial applications for chemical feeding pumps. This is because of their capacity to handle high fluid volumes. Numerous industries rely on chemical dosing pumps. These include mining, pharmaceuticals, power generation, horticulture, food processing, oil and gas, breweries, and agriculture.
- Disinfection and oxidation
- Relocating activated sludge for use in subsequent treatments
- Control smell in advanced treatment
- Incorporating fluoride into the water distribution system
- Keeping the pH within a predetermined range
4 Pumps often used in the chemical industry
Turbine
As a last resort, businesses often use turbine industrial pumps. The toothed impellers, which resemble turbines, effortlessly transport chemical liquids. They cannot handle fluids containing solid particles despite their efficiency and adaptability.
Positive Displacement
Industrial pumps like these spin on a central shaft. In other words, they have a rotating vane, piston pumps, gears, and screws. Compared to centrifugal pumps, positive displacement pumps are far more effective at transporting chemical fluids with high viscosities. The reason is that they produce large pumping pressures.
Diaphragm
The chemical industry also receives a substantial amount of these pumps from the top distributors of liquid handling equipment. Chemical liquids move using a reciprocating diaphragm, even though it is a positive displacement pump. Nevertheless, these have an important benefit. Their availability in plastic and metal forms makes them suitable for various substances.
Centrifugal
In particular, centrifugal pumps are widely used in the chemical sector. They are simple to use and quite effective. These pumps have a lower operating cost than the other three varieties, which is an additional perk.
This chemical pump type employs suction to drive liquids into a propeller. Cavitation is one possible drawback of centrifugal pumps. That may happen when the intake pressures are low. You may avoid this problem by getting these pumps from a reputable liquid handling equipment dealer.
