75kW High - Performance Reliable Submersible Drainage Pumps: For Swift and Comprehensive Water Evacuation
The pump is engineered for seamless, continuous operation under the following specific conditions:
The power supply for the pump is characterized by a rated frequency of 50Hz and a rated voltage of three - phase AC, available in 380V, 660V, or 1140V configurations. Customers are obligated to confirm the exact voltage value at the time of placing an order to ensure optimal pump performance.
The pump is designed to function effectively in two scenarios: either in shallow surface water or when submerged to a maximum depth of 5m. This design flexibility allows for its application in a variety of water - related environments.
Regarding temperature, the medium being pumped should not exceed 40°C. Simultaneously, the working environment temperature must be maintained within the range of 0°C to 40°C. These temperature limits are crucial for ensuring the pump's reliable and long - lasting operation.
The medium's pH value is required to fall within the range of 6 - 8. Maintaining this pH range is essential as it helps prevent corrosion and ensures the integrity of the pump's components during operation.
The volume fraction of solid impurities present in the water should not surpass 2%. Additionally, the density of the medium must be less than 1.02 x 10³ kg/m³. These parameters are vital in ensuring the pump's smooth operation and preventing damage to its internal mechanisms.
The size of solid particles in the water is restricted to not exceed 50% of the minimum cross - sectional size of the pump's flow passage. This limitation safeguards the pump from potential blockages and ensures efficient fluid flow through the system.

This product is meticulously engineered for hazardous environments where methane (commonly referred to as gas) and coal - dust present significant explosion hazards. It demonstrates exceptional proficiency in handling sewage composed of a complex mixture of insoluble solid elements, such as sediment, coal slime, cinders, and fibrous substances.
Furthermore, its application scope is vast, encompassing the transportation of rainwater and sewage containing solid particles across diverse settings. These include construction sites, hospitals, residential communities, municipal engineering undertakings, road construction projects, and factory wastewater treatment systems.
Boasting an extensive lineup of models, the power of these products varies from 2.2kW to 315kW. The flow rate spans from 10m³/h to 2500m³/h, and the head ranges from 7m to 700m. All products are ingeniously designed to operate across the entire head spectrum without the risk of overload at any point within this range, ensuring consistent and reliable performance under different operational conditions.
Standard pumps are expertly fabricated from QT600 - 3 nodular cast iron. This carefully selected material confers exceptional long - term durability, ensuring that the pump can endure the intense demands of continuous operation over extended durations. The robust construction serves as a testament to the pump's ability to withstand the rigors of various working conditions without compromising on performance.
The mechanical seals integrated into these pumps are ingeniously engineered to exhibit high - pressure resistance. This characteristic not only elevates the pump's performance but also permits deeper submergence. As a result, the pump can operate effectively across a diverse range of challenging applications, adapting to the specific requirements of each task with ease.
These pumps are equipped with a cooling jacket, a design feature that allows for operation without complete submersion in the medium. With the flow components positioned beneath the motor, the motor is water - cooled during operation. This innovative design not only prolongs the motor's lifespan but also enables the pump to function optimally even at low water levels. It represents a significant advancement in pump design, enhancing both efficiency and reliability.
The motor is cooled by the very water it pumps, a self - cooling mechanism that ensures dependable and safe operation under normal working circumstances. This self - contained cooling system is a key advantage, eliminating the need for additional cooling mechanisms and reducing the risk of overheating.
The pump's top - outlet design offers a distinct edge in terms of space utilization. It provides a more space - efficient solution, simplifying the installation process and facilitating seamless integration into various systems. This design choice is particularly beneficial in applications where space is at a premium, allowing for greater flexibility in system design.
For enhanced protection, sealed motors come with an optional built - in thermal protection feature. This safeguard acts as a crucial line of defense, preventing overheating and potential damage to the motor. By maintaining the motor's temperature within safe limits, it ensures the motor's long - term reliability and consistent performance.
A sealed pressure relief port is strategically positioned to prevent the pumping pressure from directly acting on the shaft seal. This design element not only safeguards the shaft seal but also contributes to the overall longevity and performance of the pump. By relieving excess pressure, it reduces wear and tear on the shaft seal, ensuring its continued effectiveness over time.
