Aro 637427-GG Pump Repair Kit

The Aro 637427-GG Pump Repair Kit provides replacement components for servicing compatible ARO diaphragm pumps. It includes Buna-N check balls, diaphragms, O-rings and seals to restore the fluid end. This kit suits maintenance technicians and plant engineers who need to rebuild specific pump models quickly.

Fits Listed ARO Pump Models

The kit is compatible with the manufacturer model numbers listed in the data, such as PD05A-AAS-FGG-B and PD05R-BAS-PGG-B, and matches Grainger part numbers 5XA61 and 5XA63. It will not fit pumps outside those exact model series, so buyers needing parts for other brands or unlisted ARO models should look elsewhere.

Four Check Balls and Two Diaphragms

The package contains four Buna-N check balls and two Buna-N diaphragms, along with six O-rings and eight seals. Verify the required check ball and diaphragm count against your pump specification before ordering to ensure the kit matches the fluid end configuration.
