VSD-Specific Vacuum Intake Valve：

· Coordinating with the PM VSD drive, to manage airflow during startup to ensuring rapid attainment of the target vacuum level.

· Preventing air backflow during shutdown, thereby protecting the vacuum pipeline system.

Vacuum Pump-Specific Screw Rotor Air-end：

· A dedicated design for rough vacuum applications and delivers exceptional performance.

· Featuring a rotor with large diameter and lower rotational speed for more stable operation.

· Its optimized profile and structure achieve a 12% improvement in sealing, a 15% reduction in internal leakage, and a 30% increase in overall efficiency.

· Precision machining technology ensures high sealing and low leakage in the compression chamber.

High-Performance Cooling System：

· A high-airflow, low-noise axial fan with a customized motor are regulated by the central control system to meet operation requirements.

· The advanced plate-fin heat exchanger provides an extra-large dissipation area with separate circuits for oil and air.

· This superior design ensures stable operation and protects components even in high-temperature ambient conditions.

· Ensures stable equipment operation even in high-temperature environments.

Three-Stage Vacuum Separation System：

· Stage 1: Cyclonic Separation — Utilizes centrifugal force for preliminary oil-air separation.

· Stage 2: Impaction Separation — The airflow's contact with the wall surface to further separate oil droplets.

· Stage 3: High-Efficiency Oil-Air Separator — Employs original, imported multi-layer micro-glass fiber media to remove finest oil aerosols, ensuring exceptionally clean exhaust air.

Frequently Asked Questions

• What makes the PGV series vacuum pump more energy-efficient than conventional pumps?

  The PGV series uses PM VSD (Permanent Magnet Variable Speed Drive) technology that automatically matches motor output to actual demand. This eliminates unnecessary energy consumption during low-load operation, resulting in significant savings in both energy and water usage compared to fixed-speed conventional pumps.

• How does the three-stage vacuum separation system work?

  The system separates oil from air in three progressive stages: Stage 1 uses cyclonic centrifugal force for preliminary 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 with imported multi-layer micro-glass fiber media to remove the finest oil aerosols, delivering exceptionally clean exhaust air.

• What is the expected lifespan of the PGV series compared to traditional pumps?

  Thanks to its robust construction, non-contact rotor design, and optimized screw rotor air-end, the PGV series is engineered to deliver a lifespan up to 10 times longer than conventional pumps, while supporting 7×24 uninterrupted continuous operation.

• What is the Deman Cloud Intelligent Control System and how does it help operations?

  The Deman Cloud Intelligent Control System is a built-in IoT-based monitoring platform that enables 24/7 remote surveillance of the vacuum pump's operating status. It sends real-time early-warning alerts whenever data deviations are detected, helping operators respond proactively, minimize unexpected downtime, and reduce maintenance costs.

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

  The PGV series is designed to operate with an intake air temperature range of 0–46°C. Its 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 and reliable operation even in demanding high-temperature ambient conditions.

• How easy is it to maintain the PGV series vacuum pump?

  Maintenance has been simplified through smart-positioned consumables design. The oil separator features a dedicated maintenance panel on its top cover, allowing quick and easy replacement of the oil separation element. This design significantly minimizes downtime and reduces overall service costs during routine maintenance.
