⚠️
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 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.
Q
What is the limiting pressure for all ZJQ pump models?
All models in the ZJQ series — from ZJQ-300 to ZJQ-5000 — 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 a ZJQ pump?
The motor power is not fixed — it is determined based on the actual working pressure difference of your application. Each model provides a rated power range (e.g., 5.5～37 KW for ZJQ-300), and the appropriate motor is selected according to specific operating conditions.
Q
Does the water consumption change between different ZJQ models?
Yes. Water consumption varies depending on both the model selected and the actual working pressure difference. Higher pressure differences typically require greater cooling capacity and therefore increased water usage.
Q
What are the intake and exhaust diameter options across the ZJQ series?
The intake and exhaust diameters range from 125 mm (ZJQ-300) up to 400 mm (ZJQ-5000). Models ZJQ-2500 and ZJQ-3750 share the same diameter of 350 mm, while ZJQ-600 uses 250 mm and ZJQ-1200 uses 300 mm.
Q
What operating speed (rpm) do ZJQ pumps typically run at?
ZJQ pumps operate within a narrow speed range of approximately 1460–1480 rpm. The ZJQ-300 runs at 1480 rpm, ZJQ-600 at 1460 rpm, and all larger models (ZJQ-1200 through ZJQ-5000) operate at 1470 rpm.
