Fluid Compatibility
One of the best things about the QBY diaphragm pump is how many different fluids it can handle. From strong acids to thick slurries, it takes them all in stride. The secret is the material selection — match the pump material to the fluid, and you’re good.
Material Options
•
Polypropylene (PP) – good for most acids and alkalis
•
Aluminum – lightweight, suitable for oils and fuels
•
Cast iron – tough, handles abrasive slurries
•
Stainless steel 316 – best for corrosive and food-grade liquids
Diaphragm Materials
| Material | Best For |
|---|---|
| Nitrile (NBR) | Oils, fuels, general purpose |
| Neoprene (CR) | Moderate chemicals, abrasion resistance |
| Fluorocarbon (FKM) | Strong acids, solvents, high temperature |
| PTFE (Teflon) | Almost all chemicals, high purity |
Real-World Examples
•
Sulfuric acid transfer in chemical plants
•
Caustic soda handling in water treatment
•
Paint and solvent circulation in coating lines
•
Clay slurry pumping in ceramic factories
•
Waste oil collection in automotive shops
Applications Summary:
acid transfer, alkali handling, solvent circulation, paint pumping, ceramic slurry, waste oil collection, chemical processing
