Condensate Pump

Whether in industrial production or residential facilities, steam is widely used as a versatile energy source. After steam releases its heat during heat exchange, the resulting condensate still contains approximately 20% of the total energy. Discharging this condensate directly leads to significant waste of both heat and water resources. By implementing an efficient condensate recovery system, enterprises can capture this valuable resource, resulting in substantial savings and considerable economic benefits through reduced energy and water costs.

Working Principle

  • Inlet and Exhaust Process: Initially, the inlet check valve opens while the outlet check valve remains closed due to high back pressure. Water begins to enter the pump, causing the float to be in a low position. As the water level rises, the exhaust valve opens, and the float reaches its highest position, triggering the controller to switch to a neutral state.
  • Inlet Steam (Gas) Drainage: Once the float reaches a high position, the controller activates, closing the exhaust valve and opening the power steam (or air) inlet. Steam is injected into the valve, pushing the condensate in the pump to a high-pressure area using steam pressure. During this process, the inlet check valve remains closed due to the high internal pressure. When the float drops to a low position, the controller switches again, closing the power steam inlet, opening the exhaust valve, and initiating the next cycle.

Performance Characteristics

  • Non-Electric Drive: The pump is powered by steam or compressed air, making it explosion-proof, safe, and suitable for any environment.
  • Compact Structure: It has no specific installation requirements and can operate normally even in open environments.
  • Automatic Control: The water output is automatically adjusted based on the intake. As the volume of condensate increases, the working frequency accelerates; when it decreases, the frequency slows down. The pump stops when there is no condensate.
  • Cavitation-Free Operation: It completely eliminates the cavitation issues found in electric pumps.
  • Durable Construction: All internal parts are made of stainless steel, and special materials are used to ensure optimal performance and longevity.

The significance of recovering condensate

  • Reduce water treatment costs.
  • Reduce water usage and costs.
  • Reduce boiler blowdown and save fuel.
  • Avoid the cost of high temperature discharge of sewage.
  • Recovering condensed water means recovering a large amount of heat
  • energy, saving energy consumption and reducing usage costs.
