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 across the ZJQ pump series?
The ZJQ pump series offers a maximum suction rate ranging from 300 L/S (ZJQ-300) up to 5000 L/S (ZJQ-5000), allowing users to select the appropriate model based on their specific vacuum capacity requirements.
Q
What is the limiting pressure for all ZJQ series models?
All models in the ZJQ series share a uniform limiting pressure of 15,000 Pa, ensuring consistent vacuum performance across the entire product range regardless of model size.
Q
How is the motor power determined for a specific ZJQ pump model?
The motor power is not fixed — it is determined based on the actual working pressure difference in your application. Each model offers a rated power range (e.g., ZJQ-1200: 15～132 KW), and the appropriate motor within that range is selected according to your specific operating conditions.
Q
Does the cooler specification change depending on the working pressure?
Yes. The heat exchange area of the cooler is directly related to the actual working pressure difference. Different pressure differences will require different cooler configurations to maintain safe and efficient pump operation.
Q
What are the intake and exhaust diameter options for large-capacity ZJQ models?
For the larger capacity models, the intake and exhaust diameters are as follows: ZJQ-2500 and ZJQ-3750 both use 350 mm diameters, while the ZJQ-5000 uses a 400 mm diameter, supporting high-volume gas flow requirements.
Q
Will water consumption vary between different ZJQ pump installations?
Yes. Water consumption varies depending on the actual working pressure difference of each installation. Since the cooler size and motor power are both pressure-dependent, the associated water consumption will differ accordingly across different applications and operating conditions.
