Aro 637309-GG Diaphragm Pump Repair Kit

This Aro 637309-GG kit supplies the balls, diaphragms and seals needed to rebuild compatible Aro diaphragm pumps. It is intended for maintenance technicians and plant engineers who service air-operated double-diaphragm pumps in industrial fluid-transfer systems. The package contains only the replacement components listed; no additional hardware or tools are included. Buyers needing a complete pump assembly or a different brand-specific kit should look elsewhere.

Maintenance Components and Operational Impact

Fresh diaphragms and seals restore the pump’s original sealing performance, reducing air consumption and preventing fluid bypass during operation. Replacing worn balls eliminates internal leakage that can cause erratic cycling and pressure drop. The kit enables a full wet-end overhaul without sourcing individual parts separately. No power-draw, thermal or noise specifications are provided for this repair kit.

Questions about this item

How do I install the Aro 637309-GG diaphragm pump repair kit and what step is commonly missed?

Shut off and depressurise the pump, remove the air valve and fluid chambers, replace the diaphragms, balls and seals from the kit, then torque the fasteners to the manufacturer's specification — the step most often missed is re-torquing after the first few cycles.

What maintenance or replacement will the Aro 637309-GG kit need later?

The diaphragms, balls and seals in this kit are wear parts; inspect them at each scheduled service and replace the set again when leakage, reduced flow or erratic cycling appears.
