    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 Housing—Bronze is more corrosion resistant than steel.
    316 Stainless Steel Housing—316 stainless steel pumps provide the most corrosion resistance.

    Corrosion-Resistant Steam Condensate Pumps with Tank

    The stainless steel tank has excellent corrosion resistance. Designed for use in low-pressure steam systems, these pumps capture steam in the attached tank and return hot condensate to your boiler or feed unit. They are activated by a float switch, turning on and off when condensate level reaches a certain depth.

    Long-Life High-Flow Steam Condensate Pumps with Tank

    To handle high condensate volume, the workload is distributed between two pumps for a longer service life than standard high-flow steam condensate pumps. The second pump provides redundancy so one pump can operate while you work on the other. These pumps move a higher volume of condensate than standard steam condensate pumps. Use them in low-pressure steam systems to capture hot condensate and return it to your boiler or feed unit. Pumps turn on when the tank is 2/3 full and turn off when condensate drops to 6" deep.

    Seal with Retainer

    and Straight Spring

    For use in waste water, boiler feed, and compressor pumps, these seals have an extra-long spring that accommodates variations in seal cavity length. They come furnished as two pieces—the seal and the seat. The seal is comprised of the case, spring, diaphragm, and washer, which come locked together as one piece. Seal Width represents the working height, which is the compressed length when installed. The seat is comprised of the seat and the gasket.
    Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.
    EPDM Diaphragm—EPDM diaphragms are more resistant to water and steam than Buna-N and Viton® fluoroelastomer, but aren’t as resistant to oils and chemicals.
    Carbon Washer—Carbon washers are for use with clean liquids.
    Cannot Be Sold Outside North America—Products cannot be sold outside North America due to restrictions.
