⚠️
Note: The motor power of the pump, the heat exchange area of the cooler, and the water consumption are determined based on the actual working pressure difference. Different pressure differences require different motors and coolers, and the water consumption will also vary.
💬 Frequently Asked Questions
Q
What is the maximum suction rate available in the ZJQ series?
The ZJQ-5000 model offers the highest maximum suction rate of 5000 L/S, making it suitable for large-scale vacuum applications requiring high throughput.
Q
Is the limiting pressure the same across all ZJQ models?
Yes, all models in the ZJQ series share a uniform limiting pressure of 15,000 Pa, ensuring consistent vacuum performance across the entire product range.
Q
How is the motor power determined for each ZJQ pump model?
The motor power is not fixed — it is selected based on the actual working pressure difference of your application. Each model provides a rated power range (e.g., ZJQ-300: 5.5～37 KW), and the appropriate motor is chosen accordingly.
Q
Does the cooler specification vary between models or configurations?
Yes, the heat exchange area of the cooler is determined by the actual working pressure difference. Different operating conditions will require different cooler specifications to ensure efficient thermal management.
Q
What are the intake and exhaust diameters for larger models like ZJQ-2500 and ZJQ-3750?
Both the ZJQ-2500 and ZJQ-3750 models share the same intake and exhaust diameter of 350 mm, while the ZJQ-5000 uses a larger 400 mm diameter to accommodate higher flow volumes.
Q
Will water consumption differ depending on the working pressure difference?
Yes, water consumption varies based on the actual working pressure difference. As the pressure difference changes, both the motor and cooler configurations are adjusted, which directly affects the overall water consumption of the system.
