ASAB DDP18 Replacement Parts #47 - Standard Suction Screen

Part Code: ASAB-SDDP18-47

Introducing the ASAB DDP18 Standard Suction Screen — a reliable inlet screen designed to protect your ASAB DDP18 double diaphragm pump by catching debris before it reaches the check valves and fluid section. It’s your first line of defence on the suction side, helping reduce blockages, minimise valve damage, and keep flow consistent — especially when pulling from open buckets, drums, or IBCs where contamination is always lurking.

A blocked, torn, or deformed suction screen is a common cause of slow priming, surging/pulsing, cavitation, and reduced output. Replacing the screen is a quick, low-cost fix that can save you a bigger wet-end rebuild later. The ASAB-SDDP18-47 is the correct standard replacement to keep suction flow clean and stable.

Whether you’re doing preventative maintenance or sorting a pump that’s starving for product, the ASAB DDP18 Standard Suction Screen is a workshop-ready solution for dependable inlet filtration.

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 suction screen.

• Keep it clean: Rinse/clean the screen in a suitable solvent/wash before refitting; don’t push debris back into the suction housing.

• Check for air leaks after reassembly: A poor seal on the suction side will cause prime issues (bubbles/surging).

• Don’t run damaged screens: If the mesh is split or the frame is distorted, replace it — debris will get through and chew valves/seats.

• Prime and test gradually: Prime at low air pressure first, confirm steady flow with no bubbles, then return to operating conditions.
