❓ Frequently Asked Questions
Q
What is the difference between the ZJP and ZJ series models?
The ZJP series (ZJP-30 to ZJP-600) are smaller-capacity models with lower suction rates ranging from 30 to 600 L/S, designed for light to medium-duty applications. The ZJ series (ZJ-1200 to ZJ-5000) are high-capacity models suited for large-scale industrial vacuum requirements, offering suction rates from 1200 to 5000 L/S.
Q
Which model is recommended for high-capacity vacuum applications?
For high-capacity applications requiring maximum throughput, the ZJ-5000 is the top-performing model, offering a maximum suction rate of 5000 L/S, a motor power of 37 kW, and an intake diameter of 400 mm, making it ideal for large industrial vacuum systems.
Q
What noise levels can I expect from these pump models?
Noise levels range from ≤78 dB(A) for the ZJP-30 and ZJP-70 models up to ≤88 dB(A) for the ZJ-5000. Smaller models are noticeably quieter, making them more suitable for noise-sensitive environments. Appropriate hearing protection and soundproofing measures are recommended for higher-capacity models.
Q
How do I select the right intake and exhaust pipe diameter for installation?
The intake and exhaust pipe diameters vary by model, ranging from 80 mm intake / 50 mm exhaust on the ZJP-30, up to 400 mm / 400 mm on the ZJ-5000. It is essential to match your piping system's diameter to the selected pump model to ensure optimal flow efficiency and avoid pressure losses during operation.
Q
What motor power is required for the mid-range models?
Mid-range models such as the ZJP-300 and ZJP-600 require motor powers of 4 kW and 7.5 kW respectively. The ZJ-1200 steps up to 11 kW. Always ensure your electrical supply and motor driver are rated appropriately for the selected model's power requirements before installation.
Q
Are these pumps suitable for continuous high-speed industrial operation?
Yes. Most models in the ZJ/ZJP series operate at speeds between 2840 and 2940 r/min, making them suitable for continuous industrial operations. The consistent high-speed design ensures stable vacuum performance. Regular maintenance and proper installation per manufacturer guidelines are recommended to maximize service life and reliability.
