❓ Frequently Asked Questions
Q
What is the maximum suction rate available across the ZJP/ZJ pump series?
The ZJ-5000 model offers the highest maximum suction rate in the series at 5000 L/S, making it ideal for large-scale industrial vacuum applications requiring high throughput.
Q
What is the noise level range for the ZJP and ZJ series pumps?
The noise levels range from ≤78 dB(A) for the smaller models (ZJP-30 and ZJP-70) up to ≤88 dB(A) for the largest model (ZJ-5000). Appropriate hearing protection should be considered for models operating at higher noise levels.
Q
How do I choose the right model based on intake and exhaust pipe diameter?
Intake and exhaust pipe diameters increase proportionally with the pump's capacity. For example, the ZJP-30 has an 80 mm intake and 50 mm exhaust, while the ZJ-5000 uses 400 mm for both intake and exhaust. Always match pipe diameters to your existing pipeline specifications to ensure optimal performance and avoid pressure loss.
Q
What motor power is required for mid-range models like ZJP-300 and ZJP-600?
The ZJP-300 requires a 4 kW motor, while the ZJP-600 requires a 7.5 kW motor. When planning your installation, ensure your electrical supply and motor driver are rated to handle the specified power requirements for safe and efficient operation.
Q
Why do most models in this series operate at speeds around 2880–2940 r/min?
The majority of ZJP/ZJ series pumps are designed to operate near synchronous speeds of 2880–2940 r/min, which corresponds to standard 50 Hz two-pole motor configurations. This ensures compatibility with widely available industrial motors and stable, efficient vacuum performance.
Q
Can the ZJP-30 and ZJP-70 models be used in the same pipeline system given they share the same pipe diameters?
Yes, both the ZJP-30 and ZJP-70 share identical intake (80 mm) and exhaust (50 mm) pipe diameters, making them physically interchangeable within the same pipeline layout. However, note that the ZJP-70 operates at nearly twice the speed (2840 r/min vs. 1420 r/min), delivering significantly higher suction capacity while consuming the same 1.5 kW of motor power.
