Frequently Asked Questions
Q
What does PM VSD technology mean and how does it save energy?
PM VSD stands for Permanent Magnet Variable Speed Drive. This technology continuously adjusts the motor output speed to match actual vacuum demand in real time, eliminating unnecessary energy consumption during low-load periods and significantly reducing both energy and water usage compared to fixed-speed conventional pumps.
Q
Why does this screw vacuum pump have a lower failure rate than traditional pumps?
The pump uses non-contact rotors, meaning there is no physical friction between moving parts during operation. This design eliminates wear-related failures, enabling continuous 7×24 operation with a failure rate up to 90% lower than traditional pumps that rely on contact-based mechanical components.
Q
What is the extreme pressure this vacuum pump can achieve?
All models in the PGV series can achieve an extreme pressure of 0.35 mbar(a), making them well-suited for rough vacuum applications that require stable and deep vacuum levels across a wide range of industrial processes.
Q
How does the three-stage vacuum separation system work?
The system uses three sequential stages: Stage 1 employs cyclonic separation using centrifugal force for initial oil-air separation; Stage 2 uses impaction separation where airflow contacts the wall surface to remove additional oil droplets; Stage 3 uses a high-efficiency oil-air separator with imported multi-layer micro-glass fiber media to capture the finest oil aerosols, delivering exceptionally clean exhaust air.
Q
What is the Deman Cloud Intelligent Control System and what benefits does it offer?
The Deman Cloud Intelligent Control System is a built-in cloud connectivity feature that enables 24/7 remote monitoring of the pump's operating data. It automatically sends real-time early-warning alerts whenever data deviations are detected, allowing operators to take preventive action before failures occur and significantly reducing unexpected downtime losses.
Q
Can this vacuum pump operate reliably in high-temperature environments?
Yes. The pump is equipped with a high-performance cooling system featuring a high-airflow, low-noise axial fan and an advanced plate-fin heat exchanger with separate circuits for oil and air. This design ensures stable operation and protects internal components even under high-temperature ambient conditions, with an intake air temperature range of 0–46°C across all models.
