SKU:637396-TT
$585.09
ARO 637396-TT pairs PTFE diaphragms with Teflon/PTFE balls to rebuild the wetted side of PD10P EXP pumps. Parts data ties it to a dozen pump models.
WHERE TO BUY?
The ARO 637396-TT is the PTFE variant of the 637396 EXP service kit. The spec table lists PTFE for the diaphragm and Teflon/PTFE for the balls, so both wear groups share a PTFE-based construction. Every pump in its fit list is a PD10P model whose code ends in TT, matching that material choice.
Diaphragms flex with each stroke to move fluid, while the balls lift and reseat to keep it flowing one way. Renewing both at once returns the fluid section to a known condition.
When to Use This Kit
- Fluid appears at the air exhaust, a typical sign of a split diaphragm.
- Flow drops or the pump loses prime because the balls no longer seal on their seats.
- A PD10P pump with PTFE wetted parts is due for its scheduled rebuild.
