Frequently Asked Questions
Q
What is PM VSD technology and how does it save energy in these vacuum pumps?
PM VSD (Permanent Magnet Variable Speed Drive) technology continuously adjusts the motor's output speed to match actual vacuum demand. Unlike conventional fixed-speed pumps that run at full power regardless of load, the PM VSD system only uses as much energy as needed — significantly reducing electricity consumption and water usage in daily operations.
Q
How much lower is the failure rate compared to traditional vacuum pumps?
Thanks to non-contact rotor design, the failure rate is up to 90% lower than that of traditional vacuum pumps. The pump is engineered for 7×24 continuous operation, making it ideal for demanding industrial environments where unplanned downtime is costly.
Q
What makes the screw rotor air-end design unique for vacuum applications?
The vacuum pump-specific screw rotor air-end is purpose-built for rough vacuum applications. It features a large-diameter rotor with lower rotational speed for stability. Its optimized profile achieves a 12% improvement in sealing, 15% reduction in internal leakage, and 30% increase in overall efficiency — all backed by precision machining technology.
Q
How does the three-stage vacuum separation system ensure clean exhaust air?
The system works in three progressive stages: Stage 1 uses cyclonic centrifugal force for initial oil-air separation; Stage 2 employs impaction separation by directing airflow against wall surfaces to remove 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 monitoring features does it offer?
The built-in Deman Cloud function provides 24/7 remote monitoring of the vacuum pump's operating data. When any parameter deviates from normal ranges, the system sends real-time early-warning alerts to operators — enabling proactive maintenance and significantly reducing unexpected downtime and associated production losses.
Q
What power and flow rate options are available in the PGV series?
The PGV series offers a wide range of configurations to suit various industrial needs: from the compact PGV 6e-450 at 5.5 kW with a nominal slip rate of 450 m³/hr, up to the high-capacity PGV 37e-2200 at 37 kW with a nominal slip rate of 2,200 m³/hr. All models operate at an extreme pressure of 0.35 mbar(a) and support an intake air temperature range of 0–46℃.
