Start with the installed pump
一个WILDEN隔膜订单需要的不仅仅是口径和PTFE字样。 记录完整的标牌型号、隔膜零件编号和相关的爆破图参考。 设备安全隔离和清洁后,拍摄标牌和拆除部件的两侧。
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 | 为什么这很重要 |
|---|---|---|
| 材质 | Wetted-face material and any separate backing | 材料标签并不标识完整的装配体。 |
| 设计 | Reduced-stroke, full-stroke or integral-piston construction, as documented | 不同的设计可能需要不同的相关组件。 |
| 供应范围 | 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.
具体的零件编号示例
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检查每个包含的项目和数量,而不是假设包裹照片定义其内容。
检查过程以及配合
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.
