ASAB DDP18 Replacement Parts #14 - Snap Ring

Part Code: ASAB-SDDP18-14

Introducing the ASAB DDP18 Snap Ring — a critical retention component used in DDP18 Double Diaphragm Pump assemblies to securely locate and hold key internal parts in position during operation. Built for reliable service under constant vibration and cycling, this snap ring helps maintain correct component alignment and prevents movement that can lead to wear, leaks, or premature failure.

Snap rings can fatigue, deform, or lose tension over time — especially if they’ve been removed and refit multiple times, or if a pump has seen heavy duty cycles. Replacing the snap ring during servicing is smart practice to ensure the assembly stays locked in place and the pump remains stable and dependable.

Whether you’re doing a wet-end rebuild, replacing diaphragms, or refreshing wear parts during preventative maintenance, the ASAB DDP18 Snap Ring is the right part to keep your DDP18 assembled correctly and running smoothly.

Safety Check

• Isolate and depressurise first: Shut off air supply, bleed the air line fully, and confirm the pump is not pressurised before disassembly.

• Eye protection mandatory: Snap rings can spring free during removal/installation — wear safety glasses and keep your face clear.

• Use proper snap ring pliers: Avoid screwdrivers or picks that can slip and damage sealing faces (or your knuckles).

• Inspect the groove: Ensure the snap ring groove is clean and undamaged so the ring seats fully.

• Don’t reuse distorted rings: If it’s stretched, bent, or has lost tension, bin it — it can pop out in service.

• Test after assembly: Repressurise gradually and check for abnormal cycling or movement before returning to full operation.
