Here’s a number most people never put on the spreadsheet: what an air-operated pump actually costs to run. The purchase price is easy to see. The compressed air it drinks, hour after hour, year after year, is the part that quietly adds up — and on a pump that runs continuously, air is usually the biggest cost of all.
Pro-Flo SHIFT is Wilden’s answer to that. Its air distribution system eases off the air near the end of each stroke, so the pump uses noticeably less than an older-generation unit doing the same work — no electronics, no adjusting, it just does it. Run it around the clock and the savings on your compressor can pay back the pump’s price on their own.
The PS range covers the whole size line-up in metal and plastic, so you don’t trade fluid compatibility for efficiency. If you tell us how many hours a day your current pump runs, we can put a rough figure on what SHIFT would save you.
