Material Selection Guide
The right elastomer keeps your pump running and your media safe.
| Material | Chemical Resistance | Temp Range | Best For |
|---|---|---|---|
| PTFE (Teflon) | Excellent — acids, solvents, aggressive chemicals | -60~260°C | Chemical plants, plating, strong acids |
| Santoprene (TPV) | Good — mild acids/alkalis | -40~135°C | General industrial, water, wastewater |
| Neoprene (CR) | Good — oils, mild chemicals | -20~100°C | General duty, oil transfer |
| Viton/FKM | Excellent — fuels, lubricants, aromatics | -20~200°C | Fuel, solvents, high-temp media |
| EPDM | Excellent — water, steam, mild acids | -40~150°C | Water, food, brewing |
Quick rule: strong acids → PTFE · general duty → Santoprene · oils & fuels → Viton · water & food → EPDM.
FAQ
How do I know which part fits my pump?
Check the part number printed on your old part or the pump nameplate. If it is unreadable, send us a photo — our team will match it for free.
Are these genuine OEM parts?
We supply OEM-compatible replacement parts manufactured to match the original specifications. We are an independent supplier and not affiliated with the original brands.
How often should diaphragms be replaced?
Depends on media and duty cycle. Aggressive chemicals and abrasive slurries can wear diaphragms in weeks; clean water applications can last 1-2 years. Monitor flow rate — a 5-10% increase often signals diaphragm wear.
Can you source a part number not listed?
Yes — send us the OEM part number and pump model. We source hard-to-find references through our parts network; most requests are answered within 24 hours.
