ARO 637432-44 Fluid Section Service Kit, PTFE/Santoprene
Fluid section kit for 6662XX diaphragm pumps with PTFE/Santoprene diaphragms and PTFE balls.
ARO 637432-44 rebuilds the fluid section of 6662XX diaphragm pumps, using PTFE/Santoprene diaphragm material and PTFE check balls.
The ARO 637432-44 Fluid Section Service Kit is built for 6662XX double diaphragm pumps. The -44 version pairs PTFE/Santoprene diaphragm material with PTFE check balls. PTFE is known for broad chemical resistance, so this pairing suits pumps that move harsh fluids.
In the fluid section, the diaphragms push product through the pump while the balls open and close against their seats to keep flow moving one way. Our data gives materials only, so use the Operators Manual for your pump to confirm the full contents and the steps for reassembly.
When to Use This Kit
- Product shows up at the air exhaust, a sign of a ruptured diaphragm.
- Flow drops or the pump loses suction lift even with normal air supply.
- The pump runs unevenly because a ball is no longer sealing on its seat.
