Steam-Powered Jet Pumps
Use plant steam to pump liquids and gases, prime pumps, and remove fumes. When high-pressure steam enters the intake, it creates suction that draws a second liquid or gas into the pump body and discharges a pressurized blend of the two. The discharge pressure is greater than the suction flow but lower than the intake pressure. Gas suction flow is calculated using steam at atmospheric pressure. They have no moving parts or seals, eliminating downtime for lubrication and repairs. They're also known as eductors, ejectors, and injectors.
Note: Liquid suction flow rate is calculated using 80 psi steam at 0-40 feet of discharge head.
Bronze is more corrosion resistant than cast iron.
316 stainless steel pumps provide the most corrosion resistance.
