LEPU SEAL  supports flexible payment methods and international trade terms to meet the requirements of customers from different markets. The standard payment method is T/T (Telegraphic Transfer), with payment arrangements depending on order value, product type, and cooperation history.

For standard orders, small orders are usually handled with full payment in advance, while larger projects or long-term cooperation customers can discuss more flexible payment arrangements based on mutual agreement.

Regarding international trade terms, LEPU SEAL  can provide solutions including FOB, CIF, DDP, and international express delivery through DHL, FedEx, or UPS. The most suitable trade term depends on factors such as destination country, transportation method, customs requirements, and the level of logistics support required by the customer.

LEPU SEAL  provides flexible delivery solutions according to product type, order quantity, and customization requirements. For standard mechanical seals and commonly used replacement models, delivery can usually be arranged within 15–20 days, while available stock items can be shipped faster, generally within 3–7 days depending on quantity and destination.

For customized mechanical seals produced according to customer drawings or special specifications, the lead time is typically around 30–40 days, depending on product complexity, material availability, and production requirements. For advanced products such as dry gas seals for compressors, additional manufacturing and testing processes may require a longer delivery period.

LEPU SEAL  maintains stable production capabilities and efficient manufacturing processes to support both regular orders and urgent project requirements. Fast-moving models, including commonly used replacement seal series, are also prepared for quicker response.

LEPU SEAL  offers flexible MOQ solutions for different types of mechanical seals to support both regular purchasing and customized projects. For standard models and commonly used replacement seals, we can provide relatively low MOQ options, and some fast-moving products are available from stock for quick delivery.

Our available standard and replacement products include pump mechanical seals, cartridge seals, and replacement models compatible with commonly used international pump systems, such as Burgmann equivalent seals, John Crane replacement series, Flygt pump seals, Grundfos pump seals, and other widely used models.

For customized mechanical seals manufactured according to customer drawings or special technical requirements, the MOQ will depend on factors such as product structure, material selection, tooling requirements, and production complexity.Please send your seal model, drawing, or project requirements to LEPU SEAL , and our team will confirm the suitable MOQ and pricing options for your application.

LEPUSEAL provides flexible and transparent quotation solutions based on customers’ specific requirements, helping customers select the most suitable sealing solution in terms of performance, cost, and delivery arrangements. Our quotation can be provided from three main aspects:

By Material Configuration: Since different seal face and elastomer materials directly affect sealing performance and cost, LEPUSEAL can quote different material combinations separately. Available options include carbon graphite, silicon carbide, tungsten carbide, ceramic, EPDM, FKM, FFKM, and other materials. This allows customers to compare different configurations and choose the best balance between performance requirements and budget.

By Trade Terms: LEPUSEAL supports various international trade terms, including EXW, FOB, CIF, DDP, and express delivery options such as DHL/FedEx/UPS. Each quotation clearly specifies related costs and responsibilities, helping customers understand the complete purchasing arrangement.

By Quantity: For larger order quantities, LEPUSEAL can provide tiered pricing solutions based on order volume. Each quotation also includes important details such as lead time, packing information, payment terms, and quotation validity period.

Provide your seal model, material requirements, quantity, and preferred trade terms, and LEPUSEAL will prepare a suitable quotation for your project.

LEPU SEAL provides professional after-sales support and offers a 1year limited warranty for all supplied mechanical seals.This limited warranty covers only manufacturing defects of our products. It does not cover failures caused by improper installation, off-spec operating conditions, incompatible process media, abrasion, corrosion or manmade damage.

Within the warranty period, if problems occur during operation, our technical team will communicate with you to understand actual working conditions, analyze possible root causes and provide technical support.

Mechanical seal service life is heavily affected by installation quality, equipment status, operating parameters and chemical compatibility with sealed media. Our engineers are available for technical consultation, application analysis and installation guidance to help troubleshoot issues.

If a failure is confirmed to be attributable to LEPU SEAL’s manufacturing defect, we will propose appropriate remedies such as repair or product replacement through mutual discussion.

For overseas customers, we offer continuous remote technical support including installation guidance for pump mechanical seals, cartridge seals and custom sealing solutions.
