Diaphragm pump and spare-parts ordering FAQ
Answers to common questions about pump model identification, repair kits, stock, quotations and manufacturer documents.
What if I do not know the complete pump model?
Send a clear nameplate photograph, an overall equipment photograph and any existing order reference. Include the brand and visible codes exactly as shown. For a removed component, include its location in the pump and any number on the packaging. WILLEE can review the information and identify what still needs confirmation.
Can I order a replacement by pump size alone?
No. Size is one identification field. Pump construction, material, diaphragm design and air distribution system can affect the required part. Use the complete model and part number. The WILDEN diaphragm replacement guide gives an example of this check.
Does a repair kit include every part needed for a rebuild?
Do not assume that it does. Compare the exact kit contents and quantities with the repair list. Air-side and wet-side kits have different scopes, and hardware or other components may require separate ordering. See the WILDEN repair-kit guide or our ARO repair-kit checklist.
What information is needed for a new pump quotation?
Provide the fluid and concentration, operating temperature, required flow, discharge pressure, suction conditions and connection standard. Mention solids, cleaning requirements and any required documents. Our pump selection guide helps organize the initial enquiry.
Are all catalogue products in stock?
Stock status is confirmed for the specific model and quantity. A catalogue listing describes a product reference and does not promise immediate availability. Ask WILLEE to confirm stock, price and delivery timing for your requirement.
Does WILLEE supply genuine OEM products?
WILLEE is committed to genuine OEM pump and spare-part supply. Provide the complete ordering reference and any documentation requirement so these details can be checked with the quotation. Read more about our supply and spare-parts support.
Where can I find a manual or parts list?
Use the technical library and match the document to the full equipment code and revision. If the required manual is not listed, include the model and document reference in your enquiry. A general brochure is not a substitute for the installation and maintenance manual of the installed unit.
How are delivery time and shipment details confirmed?
Send the requested quantity, destination and required timing. Availability, dispatch timing and shipment details are confirmed in the quotation discussion. Check the agreed information before approving the order.
Can a photograph prove that two parts are interchangeable?
No. Photographs help identification, but fitment must be checked using the full part reference and installed configuration. For seals, also record the component location and material. See our WILDEN gasket and O-ring guide.
How do I send an enquiry?
Use the contact page and include the model or application, quantity and the details you need confirmed. If you already have a quotation or earlier equipment record, mention it so the discussion remains tied to the same configuration.
