Centrifugal Pump For Chemical Industry – A Brief Guide
Chemicals are considered dangerous if they are toxic, highly corrosive or volatile. Chemicals can be dangerous for several reasons; they can affect a person’s health, cause litigation issues and they can pollute the environment and our food chain, such as with pesticides. An utmost car is required for its transfer.
The demand for pumps in the chemical industry is high. A chemical industry which handles toxic and aggressive acids, as well as highly flammable and explosive liquid, requires pumps. At Sujal Engineering, our pump’s performance gives protection to employees and the surrounding work environment. With our extended product range, we can offer you the right pump solution for dosing, transfer or liquid circulation as per your requirement.
Kinds of chemicals handled by pumps and types of industries
- Chemical processing in the pharmaceutical industry or the treatment of effluent
- Pickling of metals or cleaning of equipment, used in hygienic food processes (E.g. Sodium Hydroxide in a CIP process).
- Toluene or Methylbenzene, commonly used as solvents in adhesive compounds such as super glue
- Sulphuric, used in the production of fertilizers and as an electrolyte in car batteries
Often the chemicals arrive at the plant in drums or containers, from which they are transferred into the production area to reactors, storage tanks or production lines. During the production process, they become diluted, mixed with other chemicals or solids in suspension. As the chemical becomes mixed with different kind of materials, it may need to be passed through a filtration system to recover the original chemical. As these chemicals pose a threat to the local environment, they require handling in such a way that a risk of leakage or incident is mitigated or removed completely.
Centrifugal Pumps:
Centrifugal pump is the most common pump used to transfer liquid in chemical industries. Centrifugal pump work on the principle of Bernoulli’s Law. The liquid that leaves the outer diameter of impeller enters into the internal casing wall of volume. Here it stops to collect in ever-expanding exit chamber of volume. The velocity is now converted into the pressure available at the discharge nozzle because the impeller diameter and motor speed are constant. The centrifugal pump can be considered to be a constant pressure device.
Centrifugal pumps are ideal for chemical industry because they are designed specifically to transfer corrosive liquid. The advantages of using centrifugal pump are:
- Ease of operation: centrifugal pump will max out on the pressure at its dead-head pressure. This will not cause any damage to the system and it is easy to say able to work at medium to low head
- Can deal with large volumes of liquid
- Small in size, which saves a lot of space
- Low capital cost
- Easy maintenance
- No danger creates if discharge v/v is closed while starting
- Is able to work for medium to low viscous fluid
- Continuous pulsation free delivery
- Less wear and tear in case of corrosive and abrasive liquids
