Frequently Asked Questions
Q
What is the difference between ZJP and ZJ series models?
The ZJP series (ZJP-30 to ZJP-600) are smaller-capacity Roots vacuum pumps designed for lower suction rate applications, while the ZJ series (ZJ-1200 to ZJ-5000) are larger-capacity models built to handle significantly higher suction rates, larger pipe diameters, and greater motor power requirements.
Q
What is the maximum suction rate available in this product range?
The ZJ-5000 model offers the highest maximum suction rate in this range at 5000 L/S, making it suitable for large-scale industrial vacuum applications that demand high-volume gas displacement.
Q
How does motor power scale with suction rate across the product line?
Motor power increases progressively with suction rate. Entry-level models such as ZJP-30 and ZJP-70 use 1.5 kW motors, while the high-capacity ZJ-5000 requires a 37 kW motor. Selecting the right model ensures energy efficiency and optimal performance for your specific process requirements.
Q
What are the noise levels for these vacuum pumps, and are they suitable for noise-sensitive environments?
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 more suitable for environments with stricter noise requirements. Appropriate soundproofing or enclosures should be considered for larger models in noise-sensitive settings.
Q
What intake and exhaust pipe diameters should I plan for during installation?
Intake diameters range from 80 mm (ZJP-30/ZJP-70) up to 400 mm (ZJ-5000), and exhaust pipe diameters range from 50 mm to 400 mm. It is essential to match your pipeline sizing to the specified pump connections to ensure efficient airflow and avoid pressure losses during operation.
Q
Which model is recommended for medium-scale industrial vacuum systems?
For medium-scale applications, the ZJP-300 or ZJP-600 models are commonly recommended. The ZJP-300 offers a 300 L/S suction rate with a 4 kW motor, while the ZJP-600 delivers 600 L/S with a 7.5 kW motor — both providing a strong balance between performance, energy consumption, and installation footprint.
