ASAB DDP42 Replacement Parts #28 - Intake Pipe Set

Part Code: ASAB-SDDP42-28

Introducing the ASAB DDP42 Intake Pipe Set — a purpose-fit inlet pipe set designed for ASAB DDP42 double diaphragm pumps, providing a reliable, correctly sized intake path to support strong priming and consistent flow. Built for serviceability and long-term sealing, this set is ideal when you’re rebuilding the suction side, replacing damaged pipework, or restoring a setup that’s suffering from air ingress and inconsistent feed.

On AODD pumps, the suction side is everything. Intake pipework that’s cracked, dented, loose, thread-damaged, or poorly sealed can cause classic headaches like slow priming, cavitation, surging/pulsing, bubbles in the line, and reduced output—often without showing an obvious external leak. Replacing the intake pipe set brings the inlet assembly back to proper alignment and sealing so the pump can draw cleanly and run smoothly.

Whether you’re doing a wet-end rebuild, repairing job-site damage, or sorting a pump that refuses to stay primed, the ASAB-SDDP42-28 is a workshop-ready solution to keep your DDP42 feeding consistently.

Safety Check

• Isolate and depressurise first: Shut off air supply, bleed the airline fully, and ensure the pump and lines are not pressurised before disassembly.

• Chemical exposure: Wear gloves and eye protection — residual product can spill when cracking suction fittings.

• Seal integrity matters: Clean threads and sealing faces and tighten correctly — even a tiny suction leak will cause prime issues.

• Don’t force threads: Confirm thread type (BSP vs NPT where applicable) and start by hand to avoid cross-threading.

• Check filtration: Make sure the suction screen/filter is clean to prevent starvation and cavitation.

• Test prime gradually: Start at low air pressure, confirm steady flow/no bubbles, then ramp up to operating conditions.
