The P2 is the largest family in Wilden’s aluminum range: PSG lists 34 builds. Almost all of them end in /2000, and that suffix is the first thing to check when you replace a P2.
PSG describes the current pump as the “P2 redesign”. 32 of the 34 aluminum builds carry the /2000 suffix, with one each ending in /2248 and /2250. For example, the nameplate on build 02-12247-R reads P2/AAPPP/WFS/WF/AWF/2000. If your old pump has no suffix, or a different one, send us a photo of the nameplate before ordering parts, so we can confirm which design you have.
| Santoprene build (02-12247-R) | PTFE build (02-13405) | |
| Max flow | 45.2 gpm (171 L/min) | 44 gpm (167 L/min) |
| Dry suction lift | 25 ft (7.6 m) | 15.3 ft (4.7 m) |
| Max solids | 0.13 in (3.3 mm) | 0.13 in (3.3 mm) |
| Temperature | 32 to 175 °F (0 to 79 °C) | 40 to 175 °F (4 to 79 °C) |
| Shipping weight | 20 lb (9.1 kg) | 20 lb (9.1 kg) |
Note the suction lift. The Santoprene build lifts 25 ft dry, one of the best figures in the 1 inch class, while the PTFE build manages 15.3 ft. If the pump has to draw from a drum or a pit below it, the diaphragm choice matters.
Both builds are 1 inch NPT with center ports and a maximum air pressure of 120 psi (8.3 bar). Diaphragms are available in seven materials across the range.
