SKU:637375-SC
$638.55
Built for the ARO PD15A-AAP-SSC pump, this EXP service kit pairs 316 stainless steel check balls with a Hytrel diaphragm.
WHERE TO BUY?
Metal check balls are the defining feature of the ARO 637375-SC. The balls in this EXP service kit are 316 stainless steel, while the diaphragm is Hytrel. It is listed for the PD15A-AAP-SSC double diaphragm pump.
Stainless balls are heavy and hard, so they drop onto their seats quickly and resist abrasion from solids in the fluid. The Hytrel diaphragm supplies the flexing motion that draws fluid in and drives it out on alternate strokes.
When to Use This Kit
- Fluid leaks past the diaphragm into the air chamber and out of the exhaust.
- Check balls or their seats show pitting, grooves or wear rings that stop a tight seal.
- The pump chatters or short-strokes and delivery becomes uneven.
