Start with the installed pump
一個WILDEN隔膜訂單需要的不僅僅是口徑和PTFE字樣。 記錄完整的標牌型號、隔膜零件編號和相關的爆破圖參考。 設備安全隔離和清潔後,拍攝標牌和拆除部件的兩側。
This guide addresses replacement identification. For a broader comparison of material families, read our PTFE, EPDM and TPE diaphragm guide.
Separate material, design and supply scope
| 支票 | What to record | 爲什麼這很重要 |
|---|---|---|
| 材料 | Wetted-face material and any separate backing | 材料標籤並不標識完整的裝配體。 |
| 設計 | Reduced-stroke, full-stroke or integral-piston construction, as documented | 不同的設計可能需要不同的相關組件。 |
| 供應範圍 | Individual diaphragm, backing component or complete wet kit | The quoted line must cover the components actually required. |
| Installed configuration | Full pump code and manufacturer parts-list revision | Nominal size alone cannot establish interchangeability. |
Wilden offers rubber, thermoplastic elastomer and PTFE material families. Its PTFE range includes different stroke designs and backing combinations. Use the WILDEN diaphragm brochure to identify the design family, then use the manual for the installed pump to confirm the assembly.
具體的零件編號示例
WILDEN 02-1010-55 is listed as a reduced-stroke PTFE diaphragm for a nominal 1-inch pump. That description identifies a particular component; it does not approve the part for every 1-inch WILDEN pump. Confirm the backing and assembly reference before ordering it.
If several wet-side wear components are required, compare the individual parts list with the WILDEN wet-kit selection guide檢查每個包含的項目和數量,而不是假設包裹照片定義其內容。
檢查過程以及配合
Prepare the fluid name, concentration, operating and cleaning temperatures, and any abrasive solids information. A mechanically correct replacement still needs a material review for the actual exposure. When the service has changed, make the change explicit in the enquiry rather than repeating the previous order without review.
For a failed diaphragm, retain a cleaned sample and a record of the operating conditions. Our failed-diaphragm evidence guide explains how to organize that record. Installation sequence, tightening values and commissioning checks must come from the manual for the exact configuration.
Send a checkable replacement request
- 完整的泵模型和標牌照片。
- 隔膜零件編號、數量和現有支撐的識別。
- Manual reference and whether the request is for an individual part or a kit.
- Process fluid, concentration, temperature and required delivery destination.
