Frequently Asked Questions
QWhat 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 speed to match the actual vacuum demand, eliminating energy waste from running at fixed full speed. Compared to conventional pumps, it significantly reduces both energy and water consumption, resulting in lower operating costs.
QWhy does this screw vacuum pump have a lower failure rate than traditional pumps?
The pump uses non-contact rotors, meaning the internal rotating components never physically touch each other during operation. This eliminates mechanical wear at the core, enabling 7×24 continuous operation and reducing the failure rate by up to 90% compared to traditional pumps that rely on contact-based mechanisms.
QWhat vacuum pressure levels can these pumps achieve?
All models in the PGV series are engineered to achieve an extreme pressure of 0.35 mbar(a), making them suitable for rough vacuum applications that require stable and precise vacuum pressure control across a wide range of industrial processes.
QHow does the three-stage vacuum separation system work?
The three-stage system progressively cleans the exhaust air: Stage 1 uses cyclonic centrifugal force for initial oil-air separation; Stage 2 uses impaction separation where airflow contacts wall surfaces to remove oil droplets; Stage 3 uses a high-efficiency oil-air separator with multi-layer micro-glass fiber media to capture the finest oil aerosols, ensuring clean exhaust output.
QWhat is the Deman Cloud Intelligent Control System and what does it offer?
The Deman Cloud Intelligent Control System is a built-in IoT-based monitoring platform. It enables 24/7 remote monitoring of pump performance data and automatically sends real-time early-warning alerts when any data deviation is detected. This proactive approach helps prevent unexpected downtime and reduces maintenance costs.
QWhich model should I choose based on my required flow rate?
The PGV series offers models ranging from 450 m³/hr (PGV 6e-450, 5.5 kW) up to 2,200 m³/hr (PGV 37e-2200, 37 kW). Select a model whose nominal slip rate meets or slightly exceeds your process requirement.
