Sourcing FAQ

How should I compare Chinese diaphragm-pump manufacturers?
Compare proven pump designs, material compatibility, documented performance curves, quality controls, certifications, warranty terms, and after-sales support. Ask for a sample or test data when the application is demanding.
What information should I send when requesting a quotation?
Send the fluid properties, flow, pressure, temperature, solids content, materials, connection details, utilities, quantity, and required certifications. Incomplete application data can lead to an unsuitable selection.
What determines the minimum order quantity?
MOQ depends on whether the pump is a standard catalog model, a customized or branded version, and the required packaging or components. Confirm the MOQ separately for samples and production orders.
What usually affects lead time?
Lead time is influenced by model availability, diaphragm and body materials, motor or air-valve configuration, customization, certifications, and order quantity. Ask the supplier to confirm production and inspection timing in writing.
Which certifications should I request?
The relevant certification depends on the fluid, industry, location, and hazards. Request only the standards applicable to the installation and verify that certificates cover the quoted pump configuration.
