Other 1 inch Wilden pumps

If the P2 is close but not quite right, these are the neighbors at the same port size:

• P220: bolted metal pump with NPT ports, 44 gpm (167 L/min) in aluminum and 56 gpm (212 L/min) in stainless steel
• XPS220: bolted, Pro-Flo SHIFT air system, 52 gpm (197 L/min)
• P200: bolted plastic pump, 58 gpm (220 L/min) for polypropylene build 02-10560, solids up to 0.18 inch (4.6 mm)

Choosing between them is mostly about material and whether you want a clamped or bolted pump. The WILDEN pump selector narrows the list by size, material and flow.
