    Mechanical Pumping Traps

    Efficient condensate drainage is essential on all steam systems and the traditional method for this is the use of condensate steam traps.

    For condensate drainage to be possible and effective, the differential pressure between the inlet and outlet pressures of the trap must be both positive and enough to overcome the static head pressure. Therefore, the upstream pressure must be greater than the sum of the downstream pressure and the condensate return system pressure drop.

    However, in some cases, the pressure in the condensate return line is higher than the steam pressure and the steam trap does not therefore discharge condensate (or enough condensate), or primary control devices including control valves can cause a heat exchanger to stall and not return enough condensate. In these cases, and for efficient and reliable condensate drainage, a mechanical pumping trap or condensate pump can be installed for trapping at a lower upstream pressure than the one in the condensate return line.

    This equipment can be easily installed and prefabricated if required; and their use can optimise plant efficiency and product quality throughout the process.

    Mechanical Pump Sets Explained

    How Do Mechanical Pump Sets Work?

    Typically installed in ‘open’ steam systems, mechanical pump trap sets use incoming steam mains pressure as motive steam, which is let into the mechanical pump trap chamber. If the condensate level rises and is not discharged, the mechanism will lift in accordance with the float level, allowing higher pressure to enter and be used as motive pressure to return the condensate. The condensate on the mechanical pump trap will clear and the mechanism close, with the cycle then repeated as required.

    1. Condensate enters the pump chamber via the inlet swing check valve
    2. As water levels fluctuate, the float linkage opens the outlet valve and allows condensate to drain
    3. If condensate levels increase too much, motive steam is released into the pump chamber, forcing condensate through the outlet

    Features/Benefits

    • Low running and maintenance costs
    • Self-contained (no electrical supply required)
    • Ideal for humid/wet/remote applications
    • No cavitation
    • Fully automatic and self-regulating

    Typical Applications

    • Typically installed in ‘open’ steam systems for condensate recovery, mechanical pump sets can also be used for condensate removal in closed systems and condensate removal for vacuum equipment.
