Wilden P220/AAPPP/TSU/TF/ATF/0695

A recent quote request for this pump specified 10 GPM, and it’s worth being clear about what that number actually means: it’s the duty point the customer needed, not the pump’s rated capacity. The P220 — part 02-11372, model code P220/AAPPP/TSU/TF/ATF/0695 — is officially rated to 44 GPM. A pump running well below its maximum is completely normal and often preferable; it just shouldn’t be confused with the pump’s actual ceiling when comparing specs.

It’s a 1″ pump — 1″ MNPT suction, 3/4″ MNPT discharge, 1/4″ FNPT air inlet — built in aluminum with a PTFE diaphragm. PTFE handles aggressive chemicals about as well as any diaphragm material on the market, though it trades off some flex life compared to a rubber-based diaphragm under constant cycling, which is part of why it tends to show up more on pumps running intermittent or moderate duty than ones cycling nonstop.

Bare Pump or Complete Package

The compact footprint makes this a natural fit for skid-mounted equipment and dosing packages where space is tight. Worth checking on any quote: whether it’s priced as a bare pump or bundled with accessories like a 1″ inlet strainer and a 1/4″ air filter-regulator-lubricator, since those change the price noticeably and it’s an easy thing to miss when comparing two suppliers’ numbers side by side.
