When the job is heavy and the fluid is dirty rather than corrosive, cast iron earns its place. It’s tough, it’s economical for the strength you get, and it takes the abrasion and weight of wastewater, sludge and heavier transfer that would be overkill to spec in stainless.
Cast iron Wilden pumps turn up on drainage, industrial effluent, adhesives and general heavy transfer — anywhere durability matters and corrosion resistance doesn’t. Pair one with the right diaphragm and it passes solids and shrugs off dry running like any diaphragm pump.
We supply these genuine, in the common sizes, from stock. Tell us the fluid and the flow and we’ll confirm cast iron is the economical right answer — or point you elsewhere if the chemistry demands it.
