Standardized Pallets: Goods are stacked on heat-treated (ISPM 15) or plastic pallets, optimized for forklift handling. Rigid Corner Protectors: High-impact cardboard corner guards are applied to the full height of the stack. This prevents the straps from cutting into the rubber and maintains the vertical integrity of the pallet.
What materials are available for rubber diaphragms?
We offer NBR, EPDM, silicone, FKM (Viton®), neoprene, natural rubber, and custom compounds to suit specific chemical, temperature, and performance requirements.
What is the difference between fabric-reinforced and non-reinforced diaphragms?
Fabric-reinforced diaphragms incorporate a woven fabric layer for higher pressure resistance, longer stroke, and improved dimensional stability. Non-reinforced diaphragms are more flexible and suitable for lower-pressure applications.
What temperature range can rubber diaphragms withstand?
Depending on material: NBR (-30°C to +110°C), EPDM (-50°C to +150°C), Silicone (-60°C to +230°C), FKM (-20°C to +230°C).
How many cycles can a rubber diaphragm last?
With proper material selection and design, our diaphragms withstand millions of flex cycles. Cycle life depends on pressure, stroke length, temperature, and media.
Can you produce custom diaphragm profiles?
Absolutely. We manufacture flat, convoluted, rolling, dished, and fully custom profiles to your technical drawings or samples.
Are food-grade and medical-grade diaphragms available?
Yes. We offer FDA-compliant food-grade and medical-grade silicone and EPDM compounds for sanitary and healthcare applications.
What is the typical lead time for custom diaphragms?
Lead time depends on design complexity and quantity. Standard designs often ship within 7–15 working days. Custom orders typically 15–25 working days. Contact us for specific timelines.
