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.
