Frequently Asked Questions (FAQ)
Q What is PM VSD technology and how does it save energy?
PM VSD (Permanent Magnet Variable Speed Drive) technology automatically adjusts the motor output speed to match actual demand in real time. Unlike fixed-speed conventional pumps that run at full power constantly, the PM VSD system only consumes the energy needed at any given moment, resulting in significant savings in both energy and water consumption.
Q How much longer is the lifespan compared to traditional vacuum pumps?
Thanks to non-contact rotor design and robust construction, this screw vacuum pump delivers a lifespan up to 10 times longer than conventional pumps. It supports 7×24 continuous operation with a failure rate that is 90% lower than traditional pump systems.
Q What vacuum pressure range can the PGV series achieve?
All PGV series models achieve an extreme pressure of 0.35 mbar(a), making them suitable for a wide range of rough vacuum industrial applications. The advanced pressure control system ensures stable and consistent vacuum levels throughout operation.
Q How does the Deman Cloud Intelligent Control System work?
The built-in cloud control system enables 24/7 remote monitoring of the pump's operational data. When any data deviation is detected, the system automatically sends real-time early-warning alerts to operators, allowing prompt action to be taken and significantly reducing unexpected downtime and production losses.
Q What is the Three-Stage Vacuum Separation System and why is it important?
The three-stage separation system ensures exceptionally clean exhaust air. Stage 1 uses cyclonic centrifugal force for initial oil-air separation. Stage 2 uses impaction separation on wall surfaces to further remove oil droplets. Stage 3 employs imported multi-layer micro-glass fiber media to eliminate the finest oil aerosols, protecting the environment and downstream equipment.
Q Can the PGV series operate in high-temperature environments?
Yes. The high-performance cooling system — featuring a high-airflow low-noise axial fan and an advanced plate-fin heat exchanger with separate oil and air circuits — is designed to ensure stable equipment operation even in high-temperature ambient conditions. The system is regulated automatically by the central control unit to meet varying operational requirements.
