      Condensate Recovery Devices Pumping Traps GL81E

      Features/Applications

      Features

      • Energy saving

        Pumping Traps are able to pressure feed low-pressure condensate to high-pressure condensate recovery lines in higher or remote locations. The incorporation of this product enables the previously unused heat energy of condensate to be recovered and efficiently utilized, thus bringing significant benefits in terms of energy saving.

      • Electricity not required

        Pushes condensate out using the pressure of the motive medium*, therefore can easily be installed in ex-proof areas.
        No need for additional power grid for remote installations.
        *As well as steam, the motive medium can be compressed air, nitrogen gas, or other such gases.

      • Easy maintenance

        All main connections are on the cover side of the pump. Maintenance acces is easy, as it can be performed without detaching the pipes.

      • Low filling head

        The MIYAWAKI pumping traps have a very low filing head, providing good capacity without the need of higher collectors.

      Typical applications

       

      ● Recovery of low-pressure condensate (in combination with collectors)
      ● Support the discharge of condensate from heat exchangers operating close to or below 0 barg

      ● Stall elimination

      *Stall is a phenomenon where the steam trap does not work due to a drop in pressure on the device’s primary side and condensate builds up inside the device. Not only does this prevents the discharge of condensate, it also leads to an increased possibility of water hammer or heat exchanger corrosion occurring.
