⚠️
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
🔹
What is the maximum suction rate available in the ZJQ pump series?
The ZJQ pump series offers a maximum suction rate of up to 5000 L/S, available in the ZJQ-5000 model, making it suitable for large-scale industrial vacuum applications.
🔹
What is the limiting pressure for all ZJQ pump models?
All models in the ZJQ series share the same limiting pressure of 15,000 Pa, ensuring consistent vacuum performance across the entire product range.
🔹
How is the appropriate motor power determined for a ZJQ pump?
The motor power is determined based on the actual working pressure difference of your application. Since each model offers a range of rated power options, the correct motor should be selected according to the specific operating conditions to ensure efficiency and reliability.
🔹
Does a higher pressure difference affect the cooler and water consumption?
Yes. A higher pressure difference requires a larger heat exchange area for the cooler and will result in increased water consumption. It is important to evaluate the actual working pressure difference before selecting cooler specifications and planning water supply.
🔹
What are the intake and exhaust diameter options across the ZJQ series?
The intake and exhaust diameters range from 125 mm (ZJQ-300) to 400 mm (ZJQ-5000). The ZJQ-2500 and ZJQ-3750 models share the same diameter of 350 mm, while each other model has a unique diameter suited to its flow capacity.
🔹
What operating speed do the ZJQ pump models run at?
All ZJQ models operate within a narrow speed range of approximately 1460 to 1480 rpm, providing stable and consistent rotational performance across all pump sizes in the series.
