Frequently Asked Questions
What is PM VSD technology and how does it save energy in these vacuum pumps?
PM VSD (Permanent Magnet Variable Speed Drive) technology automatically adjusts the motor output speed to match the actual vacuum demand in real time. Instead of running at a fixed full speed, it reduces energy consumption and water usage by only delivering the power required at any given moment, resulting in significant savings compared to conventional fixed-speed pumps.
How does the non-contact rotor design reduce the failure rate of these screw vacuum pumps?
The non-contact rotor design eliminates mechanical friction between moving parts inside the pump. This means there is no wear from direct contact, which drastically reduces the chance of mechanical failure. As a result, the failure rate is up to 90% lower than traditional pumps, enabling reliable 7×24 continuous operation.
What makes the Three-Stage Vacuum Separation System more effective than a single-stage design?
The three-stage system combines cyclonic separation (centrifugal force), impaction separation (wall contact), and a high-efficiency multi-layer micro-glass fiber oil-air separator. Each stage progressively removes finer oil aerosols, delivering exceptionally clean exhaust air that a single-stage design cannot achieve alone, protecting downstream equipment and improving process quality.
What are the available power and flow rate options for the PGV series vacuum pumps?
The PGV series covers a wide range of applications with power options from 5.5 kW to 37 kW and nominal slip rates ranging from 450 m³/hr up to 2,200 m³/hr. All models operate at an extreme pressure of 0.35 mbar(a) and are designed for intake air temperatures between 0°C and 46°C.
How does the Deman Cloud Intelligent Control System help reduce downtime?
The built-in Cloud function enables 24/7 remote monitoring of the pump's operating data. When any parameter deviates from the normal range, the system automatically sends real-time early-warning alerts to operators. This allows maintenance teams to respond proactively before a fault escalates, significantly reducing unexpected downtime and associated production losses.
Can the PGV series vacuum pumps operate reliably in high-temperature environments?
Yes. The pumps are equipped with a high-performance cooling system that includes a high-airflow, low-noise axial fan and an advanced plate-fin heat exchanger with separate oil and air circuits. This design ensures stable operation and effectively protects internal components even when ambient temperatures are elevated, maintaining consistent performance within the specified 0–46°C intake air temperature range.
