Dry Operation
When the tank is empty, the pump protects itself and continues to operate without risk of failure.
Sector Application
Chemical Industry
Diaphragm Pump
Air diaphragm pump solutions for acids, solvents and corrosive chemicals.
Chemical Industry
Safe Transfer of Hazardous Fluids
Pump selection in the chemical industry should be made according to the chemical structure, temperature, viscosity and working pressure of the fluid being transported. Air diaphragm pumps are used safely in explosive atmospheres with their dry-running resistant structures and ATEX certified models.
Models with PP (polypropylene) and PVDF bodies provide excellent resistance to acid and alkali, while the PTFE diaphragm option offers long life operation against highly concentrated solvents.
- Dry-run resistant - the pump protects itself
- PP, PVDF, SS316L body options
- ATEX Zone 1 & Zone 2 certified models
- Suitable for viscous chemicals containing particles
- Quick maintenance with easy disassembly and assembly

Frequently Asked Questions
Things to Consider When Choosing a Chemical Pump
-
PP body is sufficient for low and medium concentration sulfuric acid. For high concentration (>70%) PVDF body and PTFE diaphragm should be preferred and chemical compatibility table should be consulted.
-
In installations with an explosive gas or dust environment (ATEX Zone 0/1/2 and Zone 20/21/22), the ATEX directive requires the use of Ex-certified equipment. Pumpport's PA series offers ATEX certified models.
-
The higher the viscosity, the lower the pump flow rate. As a general rule, if the viscosity exceeds 500 cPs, select the higher flow class. Pumpport technical team offers viscosity based selection support.
-
In heavy chemical applications, diaphragm and ball valve seals should be checked every 500-1000 operating hours. Dry operation and sudden pressure changes shorten diaphragm life.
