P/N 637389 ARO Air Section Service and Repair Kit
The ARO 637389 Air Section Service and Repair Kit is a comprehensive replacement solution designed to completely overhaul and restore the air motor section of compatible ARO 1-1/2" metallic double diaphragm pumps, including the PX15 and PZ15 series.
Built to maximize facility uptime and extend asset lifespan, this all-in-one kit includes precision U-cup packings, durable gaskets, O-rings, pilot piston components, check valve diaphragms, and a pre-measured packet of genuine Lubriplate® FML-2 grease to service both the pilot valve and major air control valve assemblies simultaneously.
By replacing worn internal components, this cost-effective maintenance kit eliminates common operational pain points like air blow-by, erratic shifting, and motor stalling—returning your industrial pump to peak pneumatic performance without the high capital expense of a full motor assembly or pump replacement. Engineered to handle maximum operating pressures safely, it relies on internal grease lubrication rather than messy external air lines to protect delicate seals.
For a successful installation, center body components should be correctly torqued during reassembly, avoiding solvent-based additives that can degrade internal materials. Please verify your pump model before ordering to ensure compatibility, as this is an air section service and repair kit only and is not a complete motor assembly or pump.
