Frequently Asked Questions
What does PM VSD technology mean and how does it save energy?
PM VSD (Permanent Magnet Variable Speed Drive) technology adjusts the motor speed in real time to match the actual vacuum demand. Instead of running at a fixed speed, the pump only consumes the energy needed at any given moment, resulting in significant energy and water savings compared to conventional fixed-speed pumps.
Why does the screw vacuum pump have a much lower failure rate than traditional pumps?
The pump features non-contact screw rotors, meaning there is no mechanical friction between internal components during operation. This eliminates a primary cause of wear and failure, enabling 7×24 continuous operation and reducing the failure rate by up to 90% compared to traditional pump designs.
What is the expected service lifespan of the PGV series vacuum pump?
Thanks to its robust construction, optimized rotor design, and high-performance three-stage separation system, the PGV series delivers a service lifespan up to 10 times longer than conventional vacuum pumps, significantly reducing total cost of ownership over time.
How does the Deman Cloud Intelligent Control System work?
The built-in cloud module connects the pump to a remote monitoring platform that operates 24/7. It continuously tracks key operating parameters and automatically sends real-time early-warning alerts whenever a data deviation is detected, allowing maintenance teams to respond proactively and minimize unexpected downtime losses.
Can the PGV series pump operate reliably in high-temperature environments?
Yes. The pump is equipped with a high-performance cooling system featuring a high-airflow axial fan and an advanced plate-fin heat exchanger with separate oil and air circuits. This design ensures stable operation and component protection even under high ambient temperature conditions, with an intake air temperature range of 0–46 °C across all models.
What models are available and what are the key differences between them?
The PGV series is available in seven models ranging from PGV 6e-450 (5.5 kW, 450 m³/hr) to PGV 37e-2200 (37 kW, 2,200 m³/hr). All models share the same extreme pressure rating of 0.35 mbar(a) and intake air temperature range of 0–46 °C. Models differ primarily in nominal slip rate, power consumption, inlet/outlet pipe diameter, and overall dimensions to suit different application scales.
