Part Code: ASAB-SDDP42-46
Introducing the ASAB DDP42 Suction Filter Body — the main housing component that forms the core of the suction filter assembly on ASAB DDP42 double diaphragm pumps. This body supports the filter/screen element, provides the sealing surfaces, and connects into the suction pickup so the pump gets a clean, unrestricted feed while keeping debris out of the valve section.
A cracked, warped, or thread-damaged filter body can cause all the classic suction dramas: air ingress (bubbles), slow priming, surging/pulsing, reduced flow, or persistent weeping at the filter joint. Because it’s on the suction side, even a tiny leak or damaged sealing face can make the pump behave like it’s got bigger problems than it actually does. Replacing the filter body is the correct fix when the housing won’t seal up, has been over-tightened, or has taken a hit on site.
Whether you’re rebuilding the suction setup, replacing a damaged housing, or tightening up prime reliability on a hard-working unit, the ASAB-SDDP42-46 is a workshop-ready solution to keep your DDP42 feeding cleanly and consistently.

What’s Included

DDP42 Suction Filter Body — ASAB-SDDP42-46
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 — product can spill when opening suction components.
-
Suction-side sealing is critical: Clean threads/sealing faces and ensure seals are in good condition — tiny leaks cause major prime issues.
-
Don’t over-tighten: Filter bodies can crack or distort—tighten to seal, not to punish it.
-
Inspect the screen/element: Replace or clean the suction screen so you’re not starving the pump after reassembly.
-
Prime test gradually: Start at low air pressure, confirm steady flow with no bubbles, then ramp up to operating conditions.
