⚠️
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?
A
The highest maximum suction rate in the ZJQ series is 5000 L/S, available in the ZJQ-5000 model.
Q
What is the limiting pressure for all ZJQ pump models?
A
All models in the ZJQ series share a uniform limiting pressure of 15,000 Pa, from ZJQ-300 through ZJQ-5000.
Q
How is the motor power determined for a specific ZJQ pump model?
A
The motor power is determined based on the actual working pressure difference. Each model offers a rated power range (e.g., ZJQ-5000 supports 45～710 KW), and the appropriate motor is selected according to the specific pressure conditions of the application.
Q
Do different pressure differences affect water consumption in the ZJQ pumps?
A
Yes. Water consumption varies depending on the actual working pressure difference. Different pressure conditions also require different cooler configurations, which directly impacts the heat exchange area and overall water usage.
Q
What are the intake and exhaust diameters for the ZJQ-2500 and ZJQ-3750 models?
A
Both the ZJQ-2500 and ZJQ-3750 models share the same intake and exhaust diameter of 350 mm.
Q
What operating speed (rpm) do most ZJQ pump models run at?
A
Most models in the ZJQ series operate at 1470 rpm. The ZJQ-300 runs slightly faster at 1480 rpm, while the ZJQ-600 operates at 1460 rpm.
