There’s a simple test for when you’ve outgrown an aluminium or plastic pump: aluminium won’t stand the chemistry, and plastic won’t stand the temperature or the pressure. When you’re stuck between those two, stainless is the answer — and Wilden casts these in 316 across the whole size range, 1/4-inch up to 3-inch.
What you’re buying is corrosion resistance, the strength to run higher-pressure lines, and clean, smooth surfaces that food, pharma and electronics work all insist on. Put a PTFE diaphragm behind a stainless body and you’ve got a pump that’ll take some of the meanest fluids in industry and keep going.
Every stainless pump we ship is genuine Wilden, and we hold the common sizes and configurations. Send us the fluid, the temperature and the duty point and we’ll confirm the right model and diaphragm.
