Model: WILDEN XPS1 (Pro-Flo SHIFT, clamped)
Genuine WILDEN XPS1, the 1/2″ Pro-Flo SHIFT aluminum pump with an aluminum air side: how it compares with the P1 on temperature, lift and weight.
| Flow Rate | Up to 15.9 gpm / 60 L/min (3.6 m³/h) |
|---|---|
| Head | Max air pressure 125 psi / 8.6 bar |
| Power | Compressed air, max 8.6 bar (125 psi) |
| Inlet / Outlet Diameter | 1/2" inlet / 1/2" outlet, NPT, center ports |
| Material | Aluminum wetted path and aluminum air side; PTFE, Santoprene, Hytrel, Buna-N, EPDM or FKM diaphragms |
On paper the XPS1 and the P1 look almost the same: both are 1/2 inch clamped aluminum pumps with center ports and about 15 gpm of flow. The differences are in the air side, and they show up in the temperature range.
| P1 (Santoprene, 01-2677) | XPS1 (Santoprene, 01-11225-R) | |
| Air system | Pro-Flo | Pro-Flo SHIFT |
| Air side material | Polypropylene | Aluminum |
| Max flow | 15.4 gpm (58 L/min) | 15.9 gpm (60 L/min) |
| Dry suction lift | 17 ft (5.2 m) | 18.7 ft (5.7 m) |
| Temperature range | 32 to 175 °F (0 to 79 °C) | -40 to 225 °F (-40 to 107 °C) |
| Shipping weight | 13 lb (5.9 kg) | 13 lb (5.9 kg) |
The wider temperature range is the main reason to choose the XPS1. With a Santoprene diaphragm, PSG lists it from -40 to 225 °F, which covers outdoor sites in cold climates and warmer process liquids that a polypropylene air side cannot take. The PTFE build (01-11229-R) is rated 40 to 200 °F (4 to 93 °C), with 15.8 gpm and a dry lift of 14.2 ft (4.3 m).
Pro-Flo SHIFT is Wilden’s air distribution system designed to reduce air consumption. If air costs matter on your site, ask us for the curves of both pumps at your duty point and compare the air consumption directly.
There are 16 aluminum XPS1 builds, half of them with PTFE diaphragms.
