ARO 637375-TA EXP Fluid Section Service Kit, 1-1/2 in.
1-1/2-inch EXP fluid section kit with Santoprene diaphragm, PTFE balls, seals and grease, for PD15A pumps.
ARO 637375-TA services a 1-1/2-inch EXP fluid section with a Santoprene diaphragm, Teflon/PTFE ball, gasket, U-cup, O-ring and grease package.
The ARO 637375-TA is a fluid section service kit for 1-1/2-inch ARO EXP diaphragm pumps. ARO's notes list its contents as a grease package, gasket, U-cup, O-ring, ball and diaphragm. The diaphragm is Santoprene and the balls are Teflon/PTFE, a pairing that combines a flexible, wear-resistant diaphragm with chemically resistant check balls.
Because seals and lubricant come in the same package as the wear parts, you have the soft goods and grease for a fluid-end rebuild in a single order.
When to Use This Kit
- Fluid or residue is coming out of the exhaust, pointing to a failed diaphragm.
- The pump still runs, but discharge flow or pressure has dropped off.
