Frequently Asked Questions
Q
What is PM VSD technology and how does it help save energy in the PGV screw vacuum pump?
PM VSD stands for Permanent Magnet Variable Speed Drive. It automatically adjusts the motor output speed to match real-time vacuum demand, meaning the pump only consumes the energy it actually needs. Compared to fixed-speed conventional pumps, this results in significant savings in both energy and cooling water consumption, often reducing operating costs by 30–50%.
Q
How does the failure rate of the PGV series compare to traditional vacuum pumps?
The PGV series uses non-contact screw rotors, which eliminates the friction and wear that commonly causes failures in traditional pumps. This design enables 7×24 uninterrupted continuous operation and achieves a failure rate that is approximately 90% lower than that of conventional vacuum pumps, dramatically reducing maintenance requirements and unplanned downtime.
Q
What is the maximum ambient temperature range the PGV vacuum pump can operate in?
According to the technical parameters, the PGV series supports an intake air temperature range of 0–46°C. The integrated high-performance cooling system — featuring a plate-fin heat exchanger with separate oil and air circuits — ensures stable, reliable operation even in high-temperature ambient environments.
Q
How does the Three-Stage Vacuum Separation System work?
The three-stage separation process works as follows: Stage 1 uses cyclonic (centrifugal) separation for initial oil-air separation; Stage 2 uses impaction separation where airflow contacts the wall surface to remove further oil droplets; Stage 3 employs a high-efficiency oil-air separator using imported multi-layer micro-glass fiber media to capture the finest oil aerosols, ensuring clean, oil-free exhaust air output.
Q
What does the Deman Cloud Intelligent Control System offer for remote management?
The built-in Deman Cloud system provides 24/7 remote monitoring of the vacuum pump's operational data. If any data deviation is detected — such as abnormal temperature, pressure, or performance metrics — the system immediately sends real-time early-warning alerts to operators. This proactive monitoring helps prevent unexpected breakdowns and significantly reduces production downtime losses.
Q
Which model should I choose if my application requires a flow rate of around 1,800 m³/hr?
For an application requiring approximately 1,800 m³/hr, the PGV 30e-1800 is the ideal choice. It delivers a nominal slip rate of 1,800 m³/hr with a 30 kW motor, features a DN 150 inlet and DN 100 exhaust pipe diameter, and has overall dimensions of 2,200×1,260×1,390 mm. It achieves an extreme pressure of 0.35 mbar(a), suitable for most industrial rough vacuum processes.
