Stability — The Foundation of Energy: DHP Pumps Supporting the Safety of the Third Nuclear Power Plant
Nuclear Power Plant Wastewater System Application
DHP Submersible Pump Used in Nuclear Power Plant Facilities
During the operation of large power plants, various types of wastewater are generated from both daily facility operations and internal utility systems.
To manage these water resources efficiently, wastewater and sewage are collected in designated wastewater collection pits, where pumping systems are used to transfer the water to downstream treatment facilities for further processing.
Because these systems must operate continuously and reliably, stable and durable pumping equipment is essential for maintaining safe and efficient plant operations.
At the Third Nuclear Power Plant, the wastewater transfer system utilizes DHP Submersible Pumps to efficiently move wastewater from collection pits to the treatment system, supporting the facility’s daily water management operations.
◆ Operating Environment
Within the power plant, both domestic wastewater and facility drainage are directed into wastewater collection tanks.
Once the water level reaches a preset height, the pumping system must automatically activate to transport the wastewater to the treatment system, ensuring continuous and stable drainage operations.
The DHP Submersible Pump is equipped with an automatic float level control system, allowing the pump to start and stop automatically according to the water level inside the tank.
This automatic operation provides several important advantages:
-
Automatic water level control
-
Reduced manual operation
-
Prevention of dry running
-
Lower risk of pump damage
-
Improved overall system efficiency
Even under continuous high-duty operation, the system maintains reliable and stable performance.
◆ Durable and Reliable Pump Design
The DHP Submersible Pump is manufactured using high corrosion-resistant materials and a reinforced sealing structure, allowing the pump to operate reliably in humid and high-load environments for extended periods.
Key advantages include:
✔ Corrosion-Resistant Construction
Suitable for wastewater and drainage environments.
✔ Automatic Float Switch Control
Automatically starts and stops the pump based on water level.
✔ Stable Continuous Operation
Designed for long-term operation in demanding facilities.
✔ Reduced Maintenance Requirements
Durable construction helps lower maintenance frequency and reduce downtime risk.
