FAQ：

Q: How do I place an order?

A: Inquiry → Quotation → Sample → Order Confirmation → Deposit Payment → Production and Quality Inspection → Balance Payment →Ship

Q: Can you provide free samples

A: We do not provide free samples for the first time, but we can deduct the sample amount from future bulk orders

Q: What is your delivery time

A: For products that are in stock, we can ship them out within 48 hours. For products that are out of stock or in large quantities, we need to communicate separately.

Q: How do you control the quality?

A: We will make samples before mass production, and mass production will be arranged after samples approved. Doing 100% inspection during production, then do random inspection before packing, taking pictures after packing.

Q: What is a stationary seal?

A: Stationary seals, or hermetic seals, are used to seal non-moving pump components. So-called 'sealless' pumping systems will always feature stationary seals such as O-rings, gaskets, or diaphragms. A gasket is a flat ring or sheet, often made in complex shapes to match the opposing faces of the components to be sealed.

Q: What is the difference between rotating and stationary mechanical seals?

A: Seals with rotating primary rings are said to be “rotating” seals; seals with stationary primary rings are said to be “stationary” seals. Because the springs are always associated with the primary rings, sometimes the distinction is made as “rotating springs” versus “stationary springs”.
