The WILDEN P2 is a 1 inch clamped Pro-Flo pump. The “stainless steel option” in the title is real: Wilden lists 35 stainless P2 builds alongside 34 in aluminum, 43 in polypropylene and 27 in PVDF. This page compares the two metal versions.
| Aluminum (02-12246) | Stainless steel (02-12692) | |
|---|---|---|
| Diaphragm | Buna-N | PTFE, reduced stroke |
| Max flow | 45.5 gpm (172 L/min) | 41 gpm (155 L/min) |
| Max air pressure | 120 psi (8.3 bar) | 120 psi (8.3 bar) |
| Max solids | 0.13 in (3.3 mm) | 0.13 in (3.3 mm) |
| Dry suction lift | 17 ft (5.2 m) | 9.1 ft (2.8 m) |
| Shipping weight | 20 lb (9.1 kg) | 37 lb (16.8 kg) |
The stainless pump is almost twice as heavy, and the PTFE build loses a good part of its suction lift. If the pump must lift from a pit or drum, that difference matters more than the flow figure.
For a 1 inch bolted pump instead of a clamped one, look at the P220 and XPS220.
