ARO 637161-89-C Fluid Section Repair Kit, 1" Plastic Pump
1" plastic pump fluid section kit with Hytrel diaphragm and polyurethane balls; fits ARO 6661A4-489-C
Repair kit for the fluid section of the 1 inch non-metallic ARO 6661A4-489-C, with a Hytrel diaphragm and polyurethane balls.
The ARO 637161-89-C is a repair kit for the fluid section of a 1" plastic diaphragm pump. It combines a Hytrel diaphragm with polyurethane balls. According to the notes, the kit includes an O-ring, a grease package, a ball and a diaphragm.
Polyurethane is a tough, abrasion-resistant elastomer, which helps the balls hold up as they seat over and over. Hytrel gives the diaphragm the flex life it needs in a non-metallic pump body.
When to Use This Kit
- Delivery from the 1" plastic pump has slowed even with steady air supply.
- Liquid is present in the air exhaust or around the air section.
- Balls show scuffing or dents that keep them from closing evenly.
