ASAB DDP18 Replacement Parts #35 - Suction Hose & Fitting

Part Code: ASAB-SDDP18-35

Introducing the ASAB DDP18 Suction Hose & Fitting — a purpose-built inlet pickup component designed to deliver a reliable, airtight feed into ASAB DDP18 Double Diaphragm Pump setups. This assembly provides the suction hose section and matching fitting to help maintain consistent prime and steady flow, reducing the headaches caused by air leaks, restrictions, or tired suction hardware.

On AODD pumps, suction-side issues are the usual culprits behind slow priming, surging, cavitation, and inconsistent delivery — and a worn hose or loose/damaged fitting will let air in long before it shows a visible leak. The ASAB-SDDP18-35 is the correct replacement when you’re rebuilding a suction line, replacing a soft/kinked hose, or fixing a setup that’s pulling bubbles and refusing to behave.

Whether you’re doing preventative maintenance or sorting a DDP18 that won’t stay primed, the ASAB DDP18 Suction Hose & Fitting is a workshop-ready solution to keep the pump feeding cleanly and consistently.

Key Benefits

• Direct replacement suction hose & fitting for ASAB DDP18 configurations

• Helps restore fast priming and stable material feed

• Reduces risk of air ingress that causes surging, pulsing, and cavitation

• Ideal replacement for hoses that are split, softened, kinked, or collapsing under suction

• Improves reliability at the inlet by ensuring a secure, sealed connection

• Supports smoother pump operation by maintaining consistent inlet supply

• Built for commercial workshop and job-site use

What’s Included

• ASAB DDP18 Suction Hose & Fitting — ASAB-SDDP18-35

Safety Check

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

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

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

• Avoid kinks and sharp bends: Route the hose smoothly to prevent restriction or collapse under vacuum.

• Check inlet filtration: Ensure your suction strainer/filter (if fitted) is clean to prevent starvation and cavitation.

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