QBY Diaphragm Pump – Chemical Industry Applications for Acids and Solvents

Built for Aggressive Fluids
Chemical plants deal with some of the harshest liquids imaginable — concentrated acids, strong alkalis, volatile solvents. The QBY diaphragm pump handles these safely because the fluid never contacts moving parts. The diaphragms isolate the liquid completely.

Choosing the Right Materials
•
Polypropylene body + PTFE diaphragms​ – best for strong acids
•
Stainless steel body + FKM diaphragms​ – good for solvents and high temperatures
•
PVDF body​ – for the most aggressive chemicals

Safety Features
•
No electrical spark risk
•
No mechanical seal leaks
•
Can dead-head without damage
•
Self-priming reduces handling of chemicals

Typical Chemical Transfer Jobs
•
Hydrochloric acid unloading
•
Caustic soda circulation
•
Toluene and xylene transfer
•
Plating bath solution handling
•
Waste acid neutralization

Applications Summary:​
acid transfer, caustic handling, solvent circulation, chemical dosing, plating bath, waste neutralization, chemical processing
