ASAB DDP42 Replacement Parts #47 - Standard Filter Screen

Part Code: ASAB-SDDP42-47

Introducing the ASAB DDP42 Standard Filter Screen — the primary suction filter screen designed to protect your ASAB DDP42 double diaphragm pump by catching debris before it reaches the check valves and wet end. It’s your first line of defence on the inlet side, helping maintain clean flow, stable priming, and consistent output — especially when drawing from drums, IBCs, or open containers where contamination loves to sneak in.

A blocked, torn, or misshapen filter screen is a common cause of slow priming, surging/pulsing, cavitation, and reduced flow. Replacing the screen is a quick, low-cost fix that can save you from bigger valve and seat wear down the track. The ASAB-SDDP42-47 is the correct standard replacement to keep suction filtration working as intended and the pump feeding reliably.

Whether you’re doing routine maintenance, rebuilding the suction filter assembly, or sorting a pump that’s starving for product, the ASAB DDP42 Standard Filter 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 opening suction components.

• Chemical exposure: Wear gloves and eye protection — residual product can spill when removing the screen.

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

• Check suction seals on reassembly: A poor seal on the suction side will cause bubbles/prime issues even with a clean screen.

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

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