    Frequently Asked Questions

    Q What is PM VSD technology and how does it save energy in the PGV series vacuum pump?

    PM VSD (Permanent Magnet Variable Speed Drive) technology continuously adjusts the motor speed to match the actual vacuum demand. Instead of running at full power constantly like conventional pumps, the PGV series only consumes the energy needed at any given moment, resulting in significant energy and water savings during operation.

    Q Why does the PGV series vacuum pump have a much lower failure rate than traditional pumps?

    The PGV series uses non-contact rotors in its screw rotor air-end, which eliminates mechanical wear between moving parts. This design supports 7×24 continuous operation and reduces the failure rate by up to 90% compared to traditional contact-type vacuum pumps, drastically lowering maintenance costs and unplanned downtime.

    Q How does the three-stage vacuum separation system ensure clean exhaust air?

    The system uses three progressive stages: Stage 1 applies cyclonic centrifugal force for initial oil-air separation; Stage 2 uses impaction separation as airflow contacts internal wall surfaces; Stage 3 employs 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 output.

    Q What is the operating temperature range and can the PGV pump handle high-temperature environments?

    All PGV series models support an intake air temperature range of 0–46°C. The high-performance cooling system — featuring a high-airflow axial fan and an advanced plate-fin heat exchanger with separate oil and air circuits — ensures stable operation even in high-temperature ambient conditions, protecting internal components from heat-related damage.

    Q What remote monitoring capabilities does the Deman Cloud Intelligent Control System offer?

    The built-in Deman Cloud system provides 24/7 real-time monitoring of the pump's operating data. When any parameter deviates from the normal range, the system automatically sends early-warning alerts, allowing operators to take preventive action before a failure occurs. This significantly reduces unexpected downtime and associated production losses.

    Q Which PGV model should I choose based on my required flow rate and power?

    The PGV series covers a wide range of capacities from 450 m³/hr (5.5 kW) up to 2,200 m³/hr (37 kW). For smaller applications, the PGV 6e-450 or PGV 8e-580 are suitable. Mid-range needs are served by the PGV 11e-730 through PGV 22e-1300, while high-demand industrial processes should consider the PGV 30e-1800 or PGV 37e-2200. All models maintain an extreme pressure of 0.35 mbar(a).
