Part Code: ASAB-SDDP18-48
Introducing the ASAB DDP18 Coarse Suction Screen — a heavy-duty inlet screen designed to protect your ASAB DDP18 Double Diaphragm Pump while allowing better flow with thicker materials or higher intake volume. The coarse mesh is ideal when you’re pulling from drums/IBCs or open containers where you want to catch the big rubbish (chips, skin, flakes) without restricting the suction side and starving the pump.
A suction screen that’s too fine for the material can cause slow priming, cavitation, surging/pulsing, and reduced output — the pump simply can’t get fed. The ASAB-SDDP18-48 coarse screen is the right option when you need more breathing room on the inlet while still protecting the check valves and wet end from larger debris.
Whether you’re running higher-viscosity product, chasing better prime consistency, or replacing a damaged screen that’s been copping it on site, the ASAB DDP18 Coarse Suction Screen is a workshop-ready solution for dependable inlet filtration and smoother pump feed.
Key Benefits
-
Direct replacement coarse suction screen for ASAB DDP18
-
Higher-flow coarse mesh helps reduce inlet restriction and pump starvation
-
Helps protect check balls/seats and valve chambers from larger debris
-
Supports faster priming and more consistent feed with thicker materials
-
Can reduce symptoms like cavitation, surging, and pulsing caused by restricted suction
-
Ideal for containers where contamination is likely (drums/IBCs/open buckets)
-
Built for regular cleaning and job-site use

Safety Check
-
Isolate and depressurise first: Shut off air supply, bleed the airline fully, and ensure the pump/lines are not pressurised before removing suction components.
-
Chemical exposure: Wear gloves and eye protection — residual product can spill when removing the screen.
-
Match the screen to the material: Coarse screens stop big debris, but fine contaminants can still pass — use appropriate filtration downstream if needed.
-
Don’t run damaged mesh: If split, crushed, or deformed, replace it — debris will get through and chew valves/seats.
-
Check suction seals after refit: Any air leak on the suction side will cause bubbles/prime issues.
-
Prime and test gradually: Prime at low air pressure first, confirm steady flow with no bubbles, then return to operating conditions.
