Frequently Asked Questions
Q
What is the difference between the ZJP and ZJ series models?
The ZJP series (ZJP-30 to ZJP-600) are designed for lower to mid-range suction rates ranging from 30 to 600 L/S, while the ZJ series (ZJ-1200 to ZJ-5000) are heavy-duty models built for high-capacity applications with suction rates up to 5000 L/S and correspondingly larger intake and exhaust diameters.
Q
Which model should I choose for a high-vacuum industrial application?
For high-vacuum industrial applications requiring large pumping capacity, the ZJ-2500 or ZJ-5000 models are recommended. The ZJ-5000 offers the highest suction rate of 5000 L/S with a motor power of 37 kW, making it ideal for demanding large-scale vacuum systems.
Q
What is the noise level range across all models?
The noise levels range from ≤78 dB(A) for the smaller ZJP-30 and ZJP-70 models up to ≤88 dB(A) for the largest ZJ-5000 model. When noise is a concern in your working environment, selecting a smaller-capacity model or implementing additional soundproofing measures is advisable.
Q
What motor power is required for the ZJP-300 model?
The ZJP-300 model requires a motor power of 4 kW, operating at a speed of 2890 r/min. It features an intake diameter of 150 mm and an exhaust pipe diameter of 100 mm, with a maximum suction rate of 300 L/S.
Q
Are these pumps suitable for continuous operation?
Yes, all models in the ZJP and ZJ series are engineered for reliable continuous operation in industrial vacuum systems. The operating speeds (r/min) and motor power ratings listed in the specifications are designed to support sustained, long-term performance under normal operating conditions.
Q
How do I match the intake and exhaust pipe diameters to my existing system?
You should match the intake and exhaust pipe diameters listed in the specifications table to your existing pipeline dimensions. For example, the ZJP-150 has an intake diameter of 100 mm and an exhaust diameter of 80 mm. If your system uses different pipe sizes, appropriate reducers or adapters can be used, though it is recommended to consult with a technical engineer to avoid flow restrictions that may affect pump performance.
