Questions about this item

Does the ARO 637401-GG kit include every seal and diaphragm needed for a full rebuild?

The kit supplies 24 seals, 20 O-rings, 2 Buna-N diaphragms and 4 Buna-N check balls — the quantities specified for the compatible pump models.

Which pump models are confirmed to work with the 637401-GG repair kit?

It fits ARO models PD10A-AAP-FGG, PD10A-AAP-GGG, PD10A-AAS-GGG, PD10A-ACP-GGG, PD10A-ACS-GGG, PD10A-ASP-GGG, PD10A-ASS-GGG, PD10A-BAP-GGG, PD10A-BCP-GGG, PD10A-BSP-GGG, PD10S-ASS-GGG, PE10A-AAP-GGG-ADF, PW10A-AAP-GGG and PW10A-AAS-FGG.

How does the Buna-N material perform once the kit is installed in a pump?

Buna-N (nitrile) gives good resistance to oil, water and many solvents, so the check balls, diaphragms and seals hold up in typical fluid-transfer duties.
