ARO 637391-CC EXP Fluid Section Service Kit
Fluid section service kit with Hytrel diaphragms and Hytrel balls for the ARO PD15P-FPS-PCC pump
Fluid section service kit for the ARO PD15P-FPS-PCC EXP pump. Its diaphragm and its check balls are both made of Hytrel elastomer.
The ARO 637391-CC is an EXP fluid section service kit. Its diaphragm and its check balls are both listed in Hytrel, so the wetted wear parts in this kit share a single elastomer. It is the fluid-side service kit for the one pump named below.
Inside an air-operated double diaphragm pump, the diaphragms flex back and forth to pull fluid into each chamber and push it out again. The balls lift off their seats and drop back down so the flow can only travel one way. Renewing both together brings the fluid section back as a matched set.
When to Use This Kit
- Product shows up at the air exhaust, which usually points to a split diaphragm.
- The pump strokes at a normal rate but delivers less fluid than it used to.
- A teardown reveals Hytrel parts that are cracked, swollen or flattened where they seal.
