Armstrong offers a stainless steel sump ejector for use in draining unwanted water from steam pits, steam tunnels or enclosed spaces. The stainless steel sump ejector uses a snap-acting Inconel X-750 spring-assisted mechanism which engages a steam motive valve, turning the pump on or off as the float rises and falls. The all-stainless steel design will ensure long life in the harsh environment of a steam pit.
