Q1: What materials do you use for your high-pressure water seals?
A: We primarily use high-grade materials such as NBR (Nitrile), FKM (Viton), PTFE (Teflon), and Kevlar-reinforced fabrics. For specialized applications, we also offer materials capable of withstanding temperatures up to 200°C and pressures exceeding 500 bar.
Q2: Are your seal kits compatible with major pump brands?
A: Yes. We specialize in producing replacement seal kits for leading brands including Interpump, Annovi Reverberi (AR), HAWK, Comet, and Bertolini. All our kits are engineered to meet or exceed original equipment (OEM) specifications.
Q3: How do you ensure the quality of your seals during production?
A: We implement a strict quality control process:
1. Raw Material Inspection: Testing the hardness and elasticity of rubber batches.
2. In-process Monitoring: Precision control of vulcanization time and temperature.
3. Final Inspection: 100% visual inspection and random dimension testing using digital calipers and projectors.
Q4: Can you provide custom sealing solutions based on drawings or samples?
A: Absolutely. We offer comprehensive OEM/ODM services. If you have a unique requirement or a discontinued part, simply send us your technical drawings or a physical sample, and our engineering team will develop a precise mold for production.
Q5: What is your Minimum Order Quantity (MOQ)?
A: For standard stock items (like common O-rings or U-cups), we have no strict MOQ—even a few sets are fine. For custom-molded parts or specialized fabric-reinforced seals, the MOQ varies depending on the complexity, typically starting from 50–100 pieces.
Q6: Do you provide free samples?
A: Yes, we can provide free samples for most standard sizes. The customer only needs to cover the express shipping cost (via DHL, FedEx, or UPS).
