    Frequently asked questions

    We offer diaphragms made of NBR, EPDM, PTFE, and Viton. NBR is for oil-based media; EPDM is for water and general chemicals; PTFE and Viton are suitable for strong corrosive media like acids and alkalis.

    It depends on the pump model and conveyed medium. For abrasive media, choose ceramic or stainless steel valve balls; for corrosive media, PTFE valve balls are preferred. Valve seats should match the valve ball material to ensure sealing performance.

    Yes, our repair kits are compatible with most mainstream brands such as Sandpiper, Wilden, and ARO. Please provide your pump model and specifications before ordering.

    Absolutely. All accessories go through three rounds of inspection: raw material testing, production process sampling, and final finished product testing. Unqualified products will be rejected.

    Our products have obtained ISO 9001 quality management system certification, and some special material accessories have CE and FDA certifications, which meet the import standards of European and American markets.

    For standard accessories, the MOQ is 10 pieces per type; for customized accessories, the MOQ is negotiated based on the specific requirements.

    We support sea freight, air freight, and international express (DHL, FedEx, UPS). We can deliver to most countries and regions worldwide, with door-to-door service optional.

    Regularly clean the accessories after use, avoid mixing different media, and replace worn parts (such as O-rings and diaphragms) in time according to the usage frequency. We can provide a detailed maintenance manual upon request.
