FAQs
Explore our FAQs for quick answers to common questions. For deeper insights, check out:
Which elastomers work best for abrasive powders?
For abrasive flow we typically use high-strength elastomers and fabric-reinforced compounds that resist wear and friction. The right grade depends on particle size, flow rate, temperature and any chemicals in the process.
Can inflatable seals be used on discharge valves, chutes and transfer points?
Yes. Inflatable seals close irregular or misaligned gaps at transfer points, discharge valves and chutes, keeping dust contained while still allowing quick release when deflated.
Do your seals work in pneumatic conveying and vacuum handling?
Yes. We supply airtight seals and profiles designed for pressure and vacuum conditions in pneumatic conveying lines, receivers and vacuum transfer systems.
Do you offer food-grade and FDA-compliant materials for food or pharmaceutical powders?
Yes. FDA-compliant silicone and EPDM grades are available for food, nutraceutical and pharmaceutical powder handling, with batch traceability and documentation on request.
Do you make diaphragms for powder valves and feeders?
Yes. We manufacture rubber and PTFE diaphragms for valves, feeders and dosing equipment, built for high cycle counts in dusty, abrasive environments.
Can you manufacture custom seals for non-standard bulk handling equipment?
Yes. With in-house tooling, rapid prototyping and custom compounding, we produce non-standard profiles and seals to fit specific mixers, feeders and transfer equipment.
What is the typical lead time for custom seals for powder handling equipment?
Standard sizes are available quickly, and custom seals for powder and bulk handling equipment generally ship within 2 to 4 weeks, depending on tooling requirements, material selection and design complexity.
