ASAB DP23 Replacement Parts #7 - Diaphragm

Part Code: ASAB-SDP23-07

Introducing the ASAB DP23 Replacement Diaphragm — a genuine service component engineered to restore reliable performance in ASAB DP23 diaphragm pump systems. If your unit is struggling to prime, pulsing, losing pressure, or showing signs of material/solvent bypass, a fresh diaphragm is often the key wear part that brings it back to smooth, consistent output.

Built to handle the repeated flex cycles of diaphragm pumping, the DP23 replacement diaphragm helps maintain proper separation between the fluid section and drive side, supporting stable flow, better pressure hold, and dependable day-to-day operation. It’s the right choice for scheduled servicing or anytime you’re chasing leaks, inconsistent delivery, or reduced pumping efficiency.

Whether you’re doing preventative maintenance or fixing a pump that’s started playing up mid-job, the ASAB DP23 Diaphragm is a workshop-ready solution to get your DP23 back in the game.

Safety Check

• Depressurise fully before service: Switch to prime/relief, trigger the gun into a waste bucket, and confirm pressure is at zero.

• Isolate the machine: Disconnect power/air supply (depending on setup) before opening the pump section.

• Chemical exposure: Wear gloves and eye protection — diaphragm changes can expose you to paint/solvent trapped in the fluid section.

• Keep it clean: Dirt in sealing faces will cause leaks—clean mating surfaces before reassembly.

• Inspect related wear parts: Check housings, check balls/valves, seals, and fasteners while you’re in there.

• Pressure test gradually: After reassembly, start at low pressure and check for leaks before returning to operating pressure.
