When dealing with acids it’s important to use chemical pumps made of suitable materials resistant to corrosion and which are highly efficient with minimum maintenance. That is why, after years of experience in the industrial pumps field, we decided to use Polypropylene, PVDF and AISI316 as standard materials for our pumps.
Every material has its own properties and characteristics which make it suitable for transferring different acids. So it’s really important to choose the right pump material for every chemical application.
- Polypropylene is well known with the name Moplen (™)
- It’s a thermoplastic material extremely resistant to many solvents, bases and acids such as for example acetone, caustic soda and chloridric acid.
- It’s not suitable for concentrated, oxidizing acids.
- It’s used in many different industries for parts subjected to relatively modest forces.
- Temperature range for PP pumps is from 0° to 70°C.
Polyvinylidene fluoride (PVDF)
- It’s a thermoplastic material of the fluoropolymer family and it’s generally used in special applications requiring high purity, strength, and resistance to solvents, acids, saline solutions, alkali and bases.
- It’s mainly used with liquids such as for example sodium hypochlorite, concentrated sulfuric acid, nitric acid, gasoline.
- It doesn’t undergo deformation under loads and has a high mechanical resistance.
- Temperature range for PVDF pumps is from 0° to 90°C.
Stainless steel AISI316
- It’s a metallic material used when both the properties of steel and the resistance to corrosion are required.
- Particularly indicated for pumps working with high temperature liquids, oils, kerosene, alcohols.
- It’s used to pump acids up to a maximum temperature of 160°C
