Michael Smith Engineers Ltd are acknowledged experts in the selection of pumps for all types of chemical applications. We have over half a century of experience of choosing the correct pump technology, the correct pump material and the correct pump size for the chemical being pumped.
Chemical Pumps for Different Applications
Alkalis and Caustic Compounds
Caustic materials such as sodium hydroxide (caustic soda), potassium hydroxide and calcium oxide (quicklime) are used in a wide range of industries. For pumping these materials, it is essential that the correct pump material and pump type is chosen to avoid premature corrosion and potential dangerous leakage.
Acids
Choosing a pump for acids can be especially challenging, even for common compounds such as sulphuric acid, hydrochloric acid and nitric acid. Not only do different acids often require different pump materials, but the characteristics of acids can vary considerably depending on their concentration and/or temperature. Many acids are extremely dangerous to handle and so it is essential that the correct pump for the application is selected.
Solvents
Solvents are usually chemicals used to dissolve, suspend, and extract materials in a wide range of applications, from pharmaceutical production, paints and inks, to cleaning products. Great care needs to be taken when selecting pump for solvents as they can be highly flammable, toxic and corrosive.
There are a wide range of solvents, but some common ones are:
- Acetone
- Benzene
- Dichloromethane
- Ethanol
- Hexane
- Isopropyl alcohol
- Methanol
- Methyl ethyl ketone (MEK)
- Methylene chloride (MC)
- Trichloroethylene
- Turpentine
All these solvents, and many more, have particular characteristics, and it should not be assumed that a pump suitable for one will be suitable for another.
Polyurethane Foam Production
Polyurethane foam is a versatile material used in a wide range of applications, including seat cushions, home insulation, and heat-resistant shields for spacecraft. It is created through the reaction of polyols and isocyanates, often combined with various additives tailored to specific applications.
Selecting the right pump for polyurethane foam production presents unique challenges due to the nature of the chemicals involved. Many of these compounds are highly reactive with air, water, or other materials and can also be flammable. Therefore, careful consideration is essential when choosing a pump to ensure safety and reliability.
At Michael Smith Engineers Ltd, we have decades of experience in this field and have supplied pumps to all leading manufacturers of polyurethane foam insulation and related products.
Common Chemicals in Polyurethane Foam Production:
- Dimethyl Malonate (DEM)
- Dimethyl Pyrazole (DMP)
- Hexamethylene Diisocyanate (HDI)
- Isophorone Diisocyanate (IPDI)
- Methylene Diphenyl Diisocyanate (MDI)
- Methylethyl Ketoxime (MEKO)
- Polyol
- Toluene Diisocyanate (TDI)
