45kW Reliable Submersible Drainage Pumps: Ensuring Speedy Drainage and Thorough Water Removal
The pump is designed to operate continuously and uninterruptedly under the following conditions:
- Power Supply: The rated frequency of the power supply is 50Hz, and the rated voltage is three - phase AC 380V, 660V, or 1140V. (Customers are required to confirm the voltage value when placing an order.)
- Submersion Depth: The pump can function either in shallow surface water or when submerged to a depth not exceeding 5m.
- Temperature: The temperature of the medium should not exceed 40℃, and the working environment temperature ranges from 0℃ to 40℃.
- pH Value: The pH value of the medium should be within the range of 6 - 8.
- Solid Impurities and Medium Density: The volume fraction of solid impurities in water should not exceed 2%, and the density of the medium should be less than 1.02 x 10³ kg/m³.
- Solid Particle Size: The size of solid particles in the water should not exceed 50% of the minimum cross - sectional size of the pump's flow passage.

Standard pumps are crafted from QT600 - 3 nodular cast iron, a material choice that ensures exceptional long - term durability. This robust construction guarantees the pump can withstand the rigors of continuous operation over extended periods.
The mechanical seals incorporated in these pumps are engineered to have high - pressure resistance. This feature not only enhances the pump's performance but also allows for deeper submergence, enabling it to function effectively in a variety of demanding applications.
Equipped with a cooling jacket, these pumps are designed in a way that they need not be fully submerged in the medium. With the flow parts positioned below the motor, water - cooling of the motor occurs during operation. This innovative design not only extends the motor's service life but also enables the pump to operate efficiently at low water levels.
The motor is cooled by the pumped water itself, a self - cooling mechanism that ensures reliable and safe operation under normal working conditions.
The top - outlet design of the pump offers a distinct advantage in terms of space utilization. It is a more space - saving solution, making it easier to install and integrate into various systems.
For added protection, sealed motors come with an optional built - in thermal protection feature. This safeguard helps prevent overheating and potential damage to the motor, ensuring its long - term reliability.
A sealed pressure relief port is strategically designed to prevent the pumping pressure from acting directly on the shaft seal. This not only protects the shaft seal but also contributes to the overall longevity and performance of the pump.
Q6: I want to be your dealer, what are the conditions?
