Repair kits bundle everything needed for a planned overhaul. Wet-side kits normally include diaphragms, balls, seats, gaskets and O-rings for the fluid path, while air-side kits cover air valve components, air gaskets and dynamic seals. Using a kit saves time on part selection and ensures that all critical items are replaced at the same time, restoring pump performance close to new.

Exhaust mufflers (silencers) reduce the noise from the air outlet of an AODD pump and can help manage ice formation on the exhaust. Damaged or clogged mufflers increase back-pressure and can affect pump efficiency. We offer replacement mufflers and muffler elements suitable for plastic and metal AODD pumps so you can keep noise levels and air back-pressure under control.

O-rings are used in many sealing points: manifolds, valve seats, air valves and sometimes diaphragm plates. Even a small O-ring leak can cause air or liquid loss and unstable operation. Our program includes AODD pump O-rings in NBR, EPDM, FKM, PTFE-encapsulated and other compounds, selected according to chemical, temperature and pressure. Changing O-rings whenever the pump is opened is a low-cost way to prevent future leaks.

The piston or inner shaft connects the two diaphragms and transmits motion from the air valve to both chambers. Wear on the piston, guides or seals can lead to uneven stroke, noise and premature diaphragm failure. We supply pistons and related components for many AODD pump designs, allowing you to restore correct alignment and smooth reciprocating motion during a major overhaul.

Bonzer Marketeers supplies high-quality OEM-compatible AODD pump shafts and shaft assemblies for leading brands including Wilden, ARO, Sandpiper, and more. Designed for precise fitment, durability, and smooth reciprocating performance, these components play a critical role in transferring motion between diaphragms for efficient pump operation. Our shaft assemblies are suitable for industrial maintenance, repair, and complete pump overhauls, helping reduce downtime and extend pump life.

Center shafts and connecting shafts carry the diaphragms and transmit the reciprocating movement across the pump. Corrosion, wear at the diaphragm mounting face or bending from mis-installation can all shorten diaphragm life. We offer replacement AODD shafts machined to correct OEM dimensions so that diaphragms seat properly and the pump runs true. Installing a new shaft during a full rebuild can significantly extend the time between failures.
