Model: WILDEN XPS820 (NPT threaded) / XPS830 (ANSI flanged), Pro-Flo SHIFT FIT Series
Genuine WILDEN XPS820 (NPT) and XPS830 (flanged), 2″ bolted Pro-Flo SHIFT FIT aluminum pumps (181 gpm, 685 L/min): Buna-N vs FKM temperature limits.
| Flow Rate | Up to 181 gpm / 685 L/min (41.1 m³/h) |
|---|---|
| Head | Max operating pressure 125 psi / 8.6 bar |
| Power | Compressed air, max 8.6 bar (125 psi), 3/4" FNPT air inlet |
| Inlet / Outlet Diameter | 2" inlet / 2" outlet; XPS820 NPT, XPS830 ANSI flanged |
| Material | Aluminum wetted path and air side; Santoprene, PTFE, Buna-N, FKM, Hytrel, Bunalast, EPDM, Neoprene or Polyurethane elastomers |
Two pumps with the same body can have very different temperature ratings. The XPS820 and XPS830 show this clearly.
| Build | Part No. | Elastomer | Rated temperature |
| XPS820/AAAAA/BNS/BN/BN | 08-14751 | Buna-N | 10 to 180 °F (-12 to 82 °C) |
| XPS830/AAAAA/VTS/VT/VT | 08-14814 | FKM | -40 to 350 °F (-40 to 177 °C) |
Same aluminum pump, same 181 gpm (685 L/min) maximum flow, same 125 psi (8.6 bar) air limit. The only thing that changed is the diaphragm, valve ball and valve seat material, and the temperature window moved by well over 100 degrees. So for a hot fluid, choose the elastomer first and the pump second. We will confirm the exact limit for whatever build you order.
As for the 820 and 830 themselves: the XPS820 has NPT threads, the XPS830 has ANSI flanges. Both are bolted Pro-Flo SHIFT FIT pumps with 1/4 inch solids handling and 21.8 ft (6.6 m) dry suction lift. The flanged pump weighs about 113 lb (51 kg), the threaded one about 99 lb (45 kg).
Across the 56 aluminum builds of the two models, Santoprene is the most common elastomer, then PTFE.
