Product Overview

Wilden makes several pumps with 1/2 inch ports, and they are easy to confuse. Wilden lists four model families at this size. Here is what separates them.

ModelConstructionBody materialsMax flow (example build)
P1Clamped, Pro-FloAluminum, stainless steel, polypropylene, PVDF15.5 gpm (59 L/min), aluminum
XPS1Clamped, Pro-Flo SHIFTAluminum, stainless steel15.9 gpm (60 L/min), aluminum
XP1Clamped, conductive air sideStainless steel14.4 gpm (55 L/min), PTFE build
P100Bolted, Pro-FloPolypropylene, PVDF14.8 gpm (56 L/min), polypropylene

The flows are close, so the choice usually comes down to material and construction. Metal pumps are clamped. The plastic P100 is bolted, and Wilden lists 89 P100 builds in polypropylene and PVDF for corrosive chemicals. The XPS1 uses the newer Pro-Flo SHIFT air system, which Wilden designed to use less compressed air.

Limits to keep in mind

  • Solids: 0.06 inch (1.5 mm) on the P1 and P100 pages we checked, so the liquid must be fairly clean
  • Dry suction lift: 19 ft (5.8 m) for the aluminum P1 and 17 ft (5.2 m) for the polypropylene P100
  • Flow falls as discharge pressure and viscosity rise, so size from the pump curve, not the maximum

All 1/2 inch builds are listed by part number in our WILDEN lookup.
